2 ADAPT MODELER TUTORIAL ADAPT-Modeler Examples OVERVIEW This compilation contains several typical examples of floor systems that have been modeled using ADAPT-Modeler. The first example (Shiraz Building) is the same used in the tutorial manual of ADAPT-Modeler. In general, there is more than one way to define load paths for a given floor system. The options presented in the examples presented are viewed to be in line with common industry practice. i

6 1.1 Example 1 - The Shiraz Building EXAMPLES This example is the two-way flat slab used for the tutorial in the previous chapter. The completed model is contained in the Example1.DWG file included in the program CD-ROM. The model file is complete and ready to export data to ADAPT-PT. Below are sample plan outputs for the example. EX - 1

14 1.2 Example 2 - The Prosperity Slab This example is a two-way flat slab with irregular support layout, introduced in the PTI publication Design Fundamentals of Post-Tensioned Concrete Floors. Drop caps and drop panels have been included at several locations, as well as a wide shallow beam at one edge of the slab. Figures and summarize the model geometry. On the following pages are sample output for the model. FIGURE EX - 9

24 1.3 Example 3 - Slab and Beam Parking Structure This example illustrates a typical beam and slab parking deck. Sample outputs are included below. EX - 19

25 Note, the slab region, including ramp area, has been modeled all on the same level. The cutout in the slab region (between G9 and G10) represents the discontinuity at the ramp. EX - 20

26 Notice that the one-way slab was run so that only a small portion of the slab was covered. This was done with domain splitters as described in the Program and User Interface Manuals. EX - 21

27 Note, support lines along G6 through G10 are split into two support lines to reflect the discontinuity due to the ramp. Other support lines are continuous across the structure. EX - 22

30 Note, splitters are used to define the design strips in the X-direction (two slab strips and one transfer beam strip). The transfer beam loads must be adjusted in ADAPT-PT to reflect the true loading on the design strip (to include reactions of transverse beam). Splitters 1-4 are strip splitters; 5-7 are domain splitters. EX - 25

31 Note, splitter 8 is used to delineate design strips at the ramp into two separate strips at each gridline. EX - 26

32 1.4 Example 4 - The Ramson Building, Irregular Two-way Slab This example illustrates the versatility of using Modeler s splitter and connector features to assign load paths in an irregular two-way slab. The complete DWG file (Example4.DWG) has been included with the software. EX - 27
