1 PR116. Consulting Company Member POST-TENSIONING INSTITUTE SOFTWARE SYSTEM FOR STRUCTURAL CONCRETE ADAPT_products_ OVERVIEW OF ADAPT PRODUCTS The following is a short overview of ADAPT s programs and design aids. Since 1981, ADAPT s mission has been to develop and distribute the industry s leading concrete design and analysis tools. Over the years, our software products and other design aids have evolved to meet the ever increasing demands of structural engineering design offices. Today, we deliver an integrated concrete design solution that allows structural engineers to develop their projects from the conceptual design phase all the way through the creation of structural drawings and details, using just one slab model. These improvements in modeling, analysis, integrated design, and detailing have led to dramatic increases in the productivity and profitability of ADAPT users. In the near future, we plan on expanding our ADAPT-Builder Platform to supporting the modeling and design of entire concrete structures. Furthermore, we recognize the industry s push towards interoperable, specialized design and analysis tools. We are leading this effort with our open platform strategy. As part of this strategy, we have opened our software s data structures, allowing our users to easily access and transfer information back and forth between their various design programs.

2 ADAPT-Builder Platform A comprehensive and integrated solution for the analysis and design of post-tensioned and conventional concrete floor systems and beams. Developed from the ground up with ADAPT Component Technology, the ADAPT-Builder Platform is a collection of fully integrated design and analysis tools for all of your concrete floor system, foundation, and beam structures, whether with or without post-tensioning. Unlike traditional FEM solutions that rely heavily on the use of nodes and elements to represent structural elements, this solution's intuitive and easy-to-use 3D component modeling capabilities allow you to quickly model any structure using explicit concrete components like walls, beams, slab regions, and drop caps, to name a few. Because your model is based on intelligent sturcural components, modifications and maintenance of your analysis model becomes a cinch. In addition, the Builder Platform is the industry's only solution that gives you the flexibility to analyze the same 3D structural model using either the Finite Element Method (FEM) or the Equivalent Frame Method (EFM). With specialized design tools for concrete beam frames, one-way or column-supported flat slabs, parking structures, mat foundations, ground-supported slabs, and built-in building codes (e.g., American, Canadian, British, European, and Australian), ADAPT's Builder Platform will immediately streamline and improve your concrete design practice. ADAPT-PT ADAPT-RC ADAPT- Modeler ADAPT-Floor Pro ADAPT-MAT ADAPT-SOG ADAPT-Modeler, the platform s modeling engine, is used to rapidly generate 3D structural models of entire floor systems by importing dwg/dxf files, or by user-defined input. Once a slab model has been generated in ADAPT-Modeler, the user has the flexibility of analyzing and designing the entire slab system or individual design strips using ADAPT s integrated programs. This flexibility allows for rapid preliminary design using ADAPT-PT and rigorous design verification and fine-tuning using ADAPT-Floor Pro, without having to recreate input data. The next few pages provide an overview of each of ADAPT-Builder s constituent programs as well as ADAPTs other products. 2

3 ADAPT-Modeler Three-dimensional Modeling Software generates input data for ADAPT analysis and design programs ADAPT-Modeler generates 3D structural models of complete floor systems using Component Technology. Once the model is created, ADAPT-Modeler generates all the ADAPT input files for ADAPT-RC, ADAPT- PT, ADAPT-Floor Pro, ADAPT-MAT, and ADAPT-SOG. ADAPT-Modeler comes bundled with each license of ADAPT-Floor Pro, ADAPT-MAT, and ADAPT-SOG, but must be purchased separately to run with ADAPT-PT or ADAPT-RC. An export step is not required when running ADAPT-Floor Pro, ADAPT- MAT or ADAPT-SOG since ADAPT-Modeler and those programs run in the same environment. ADAPT-Modeler allows the user to either draw a 3D model of the floor system or import and transform an existing dwg or dxf drawing file of a floor system for structural modeling. ADAPT-Modeler s transformation tools convert drawing elements in a CAD file into ADAPT structural components. Next, the user specifies all material properties, loads and other design parameters. After defining the path of support lines, the program automatically divides the structure into design strips, idealizes the geometry of the strips and exports the data directly into ADAPT-PT or ADAPT-RC. Each design strip, with all of its associated input data, is then run in ADAPT-PT or ADAPT-RC, where the user quickly generates optimized design results. The program comes with an easy to follow step-by-step example, tutorial and other helpful aids to guide you through the modeling process. ADAPT-Modeler helps to reduce errors in input data and saves valuable engineering time in noncreative and repetitive data generation and verification. It enables the structural designer to concentrate on the design efforts where time is best spent! ADAPT-PT Industry Standard Post-Tensioning Software for Beams, Slabs and Floor Systems ADAPT-PT is the industry standard stand-alone program for the design of beams, slabs and floor systems post-tensioned with either bonded, or unbonded tendons. For two-way floor systems the user can base the analysis on either the Equivalent Frame Method, or the Simple Frame Method. For the post-tensioning design, the user can select between the Effective Force method and the Variable Force (Tendon Selection) method. In the Variable Force method, the software computes and accounts for the tendons friction and long-term stress losses along the length of the post-tensioned member. ADAPT-PT can handle floor slabs and slab beams with drop caps, drop panels, steps above and below, transverse beams and non-prismatic sections. Selfweight is calculated using actual dimensions and material properties. In addition to the posttensioning amount and profile, the software calculates the location and amount of the nonprestressed steel along the length of the structure for the strength and minimum requirements. The solution is presented in a clear and concise tabular form, as well as in graphical format. Output options also include a graphical summary report of all important design data, ready for transfer to structural drawings and inclusion in structural calculations. The graphical summary includes: Elevation of the member with the post-tensioning tendons in place The post-tensioning profile, elevation of control points and PT-force/number of strands Location, length and number of nonprestressed bars required over the entire member length Punching shear analysis for one-way systems, or for two-way systems Designer s comments DXF output 3

4 Flexibility in selection of cross-sectional geometry makes this software suitable for design of box girder bridges, and I-girders in addition to traditional building and parking structures. ADAPT-PT is fast, easy to master, and is the choice of production-oriented consulting engineers around the world. ADAPT-PT is offered in two versions, a low cost version referred to as Standard and a Plus version. The two programs are identical except that the Standard version is limited to 5 spans and two cantilevers. The Plus version goes up to 20 spans and two cantilevers. ADAPT-PT is a stand-alone program that can receive and process graphically generated input data from ADAPT-Modeler. ADAPT-RC Software for Design and Analysis of Nonprestressed Concrete Beams, Slabs and Floor Systems ADAPT-RC is for the analysis and/or design of reinforced concrete beams, slabs and floor systems. It is based on a single story frame, featuring the Equivalent Frame modeling of the ACI code as an option. In its design mode, the program determines the deflection and reinforcement for a user-defined geometry, material and loading. In its analysis mode, for a given floor geometry, loading and reinforcement, the software determines the capacity of the floor and compares it with the code stipulated demand. In both the design and the analysis modes, the deflections are calculated using cracked sections, with each span subdivided into 20 segments. ADAPT-RC is easy to use, yet thorough and rigorous in its formulation. Its graphical display gives a vivid account of moments, reinforcement and other parameters. ADAPT-RC handles both prismatic and nonprismatic spans, as well as supports with different boundary conditions. A solid model viewer allows the user to examine the input structure for a visual check on the accuracy of data entry. The primary application of the software is in building construction and parking structures. ADAPT-RC is offered in two versions, a low cost version referred to as Standard, and a Plus version. The two programs are identical except that the Standard version is limited to 5 spans and two cantilevers. The Plus version goes up to 20 spans and two cantilevers. ADAPT-RC is a stand-alone program that can receive and process graphically generated input data from ADAPT-Modeler. ADAPT-Floor Pro Three-dimensional Finite Element Software for Analysis and Design of Conventionally Reinforced andpost- Tensioned Concrete Floor Systems. ADAPT-Floor Pro, is a special purpose modeling, analysis and design program based on Component Technology. It performs its analysis and design using the Finite Element Method (FEM). In modeling the entire floor system, ADAPT-Floor Pro faithfully accounts for all openings, cutouts, beams, walls, columns, drop caps and drop panels. Profiled tendons in a slab or beam can be specified with any shape, in any arbitrary location, as either bundled or distributed tendons. Based on Component Technology, the user generates the structural model, using structural components such as beams, slabs, columns, and drop caps. Neither nodes nor elements are used to generate and verify the structural model. Loads can be applied at any location and in any configuration with a click of the mouse. The comprehensive results include deflection of the slab, moments and shears, prestressing and hyperstatic moments due to prestressing. Moments and shears can be summed up over the tributaries, or at user-defined sections for design purposes. 4

5 Using ADAPT s adaptive automatic meshing technique, the program discretizes the structure into an appropriate number of finite elements. The program then analyzes the structure. If desired, the user can view and edit the automatically generated mesh. ADAPT-Floor Pro comes bundled with an integrated version of ADAPT-Modeler. Using its ADAPT-Modeler capabilities, project data can be imported from a dwg or dxf file, or drafted using the drawing capabilities of the program. The software is particularly suited for irregular floor systems, where a closer approximation to the distribution of deflection, moments and shears are sought. ADAPT-FLOOR Pro comes in two versions: ADAPT-Floor Pro for nonprestressed reinforced structures ADAPT-Floor Pro for prestressed and nonprestressed structures ADAPT-MAT For Analysis and Design of Mat Foundations This Finite Element (FEM) program generates a graphical model of a ground supported slab mat with or without grade beams. The model can be generated using either an available DWG or DXF file of the foundation, or through user input. The mat can be of any irregular shape and subject to any kind of loading from above. Using an adaptive meshing and finite elements, the program analyzes the mat and determines the location, amount and length of all the reinforcement needed by computation. Where applicable, under horizontal loading or moments, the program accounts for the separation of a mat from the soil. ADAPT-SOG For Analysis and Design of Post-Tensioned Slab-On-Ground This Finite Element (FEM) program is tailored for the analysis of post-tensioned foundation slabs, with or without ribs, on either expansive or compressible soils. It is based on an Extension of the PTI method (E-PTI). The application of the software is for residential, or light industrial buildings. The program generates a graphical model of the entire foundation slabs, analyzes the foundation and performs stress checks for conformance with PTI specifications. FELT Friction, Elongation, and Long-Term Stress Losses in Prestressing FELT is a computer program for the Friction, Elongation and Long-Term stress loss computation of tendons in prestressed structures. For a given tendon geometry and stressing specification, the software computes the stresses along the tendon length. Tendon geometry can be selected from the program s pre-defined profiles, or, in the case of irregular tendons, the geometry can be input through tendon coordinates. The immediate loss computation includes the friction and seating of tendon (wedge draw-in). The long-term losses include creep, shrinkage and relaxation in steel. The computations are based on the recommendations of ACI Committee 423. The software handles both bonded and unbonded systems. As an option, for shop drawings, friction and elongation calculations can be performed without long-term stress losses. The software comes with thorough documentation, extensive examples and a section on verification. It is an effective analysis/design tool for both 5

6 consulting engineers and prestressing suppliers. FELT is multi-unit and covers the American, SI, and MKS systems of units. PULT ULTimate Strength Computation of Prestressed Sections PULT is a computer program for strength analysis or design of prestressed concrete sections. In its analysis mode, for a known geometry and reinforcement (including both prestressed and non-prestressed reinforcement) PULT computes the moment capacity of the section. In its design mode, for a given geometry and prestressing, PULT determines the nonprestressed reinforcement needed to supplement the prestressing to meet the demand of design moment. PULT can handle rectangular or T-sections with tension and / or compression reinforcement and reinforced with a single tendon. The prestressing can be bonded or unbonded. The software has a comprehensive manual, which explains its theoretical background and offers numerous examples. The software handles one layer of tension bars, one layer of compression bars, and combines the prestressing into one resultant tendon. The software is indispensable for spot-checking and verifications of existing designs of prestressed/post-tensioned members, as well as design of new sections. Fully upgraded to the windows environment, PULT now comes in one version that handle ACI American, SI and MKS units, as well as the ACI, Canadian CAN3-A23.3, and British BS8110 codes. ADAPT Post-Tensioning Details Structural Details for Building Construction The ADAPT Post-Tensioning Details is a compilation of over 80 typical details used on structural drawings for building construction. The details cover one-way and two-way floor slab systems, including the commonly used beam and slab construction in parking structures. They cover both the bonded and unbonded systems for regular and aggressive environments. They follow the latest recommendations of the Post-Tensioning Institute. The details are accompanied by several structural drawings, which describe the cross-referencing of details. The details come in two forms: on paper and in electronic media on a computer CD. The details come in American and SI units. ADAPT-Details on CD In addition to the details on paper and the associated drawings, this item includes a copy of each detail in a separate file on a CD. AutoCAD version 12 is used to save the detail. This allows the electronic files to be used on a wide platform of AutoCad versions. The details on the CD can be readily called, viewed and edited on the screen and added to structural drawings being prepared, provided the user has a software to handle AutoCad drawing formats. 6

7 ADAPT-ABI For Time-Dependent Analysis of Concrete Bridges and Frames, with or without Post-Tensioning ADAPT-ABI is a general finite element program, which performs time-dependent analysis of concrete bridges and frames, during the construction phase and after the structure is complete. ABI can investigate the effect of newly placed concrete, creep, shrinkage, relaxation in prestressing over time, aging of concrete, and variation in temperature. Its excellent graphical interface can display moments, shears, stresses and deformations for various stages of construction. The software can handle nonprestressed concrete, precast, cast-in-place, pre-tensioned or post-tensioned frames. The application of the software is for incrementally constructed bridges and frames; retrofit of concrete frames where new concrete is added, new members are added or existing members are modified; and demolition (reverse construction) of frames. Other applications include composite construction and cable-stay structures. The basic module of the software (ADAPT-ABI Basic) is self-contained and complete. Other modules enhance the capabilities of the Basic program. These are: ADAPT-Gen Module ADAPT-Gen enables the user to (i) break the structure into spans and columns, (ii) display and tabulate the solution in a span-and-column format, (iii) include automatic pattern loading, and (iv) combine different loading conditions and compile envelopes of load cases. Other features are directed toward making the software an effective production tool. ADAPT-Moving Load Module The moving load module is developed primarily for bridge construction. Using the software s library of the most common truck or trainloads, or a user-defined library, the program automatically moves the loading along a user-defined path and generates an envelope of sectional actions for combination with other loading. The moving load module of ABI is general and comprehensive. It is designed to cover all foreseeable conditions in bridge design. ADAPT- Elongation Module (includes friction and stress loss) At the completion of an ADAPT-ABI computer run, and without any additional input data, this module calculates the elongation of each of the tendons at stressing and the associated stress losses. The stress losses include the effects of friction, and the time-dependent parameters of creep, shrinkage and relaxation in prestressing. 7
