2 General ACI code General Euro Codes : BS EN with UK, Malaysian and Singapore Annexures The ACI and Euro (EN) design codes have been incorporated in the new V5. Euro codes with National Annexures of UK, Singapore and Malaysia are currently supported. More National Annexures will be will be added in the near future. RCDC now gives the option to design and detail in IS , BS 8100, CP 65, ACI 318 and EN 02 codes. General Enhanced click and edit options in Graphic window The graphical user experience has been greatly enhanced. Many new options including the ability to window select, Ctr+ select, grouping and un-grouping, ignore, design, set properties etc. have been added across modules.

3 General Rebar Mark Manager The narration of the rebar mark in drawings can be controlled by using the Rebar Mark Manager. This functionality can be accessed from: 1. Detailing and Drawings Settings for Beams and columns 2. Detailed Drawing option in Footings and Pile Caps 3. Design Settings in Slabs Any prefix to the rebar will also be reflected in the design output tables and the design calculations. Eg. If instead of the default T20, a different prefix Y20 or #20 is used, this will be visible in the outputs and the reports. Using this functionality the narration of each reinforcement of each type viz. longitudinal, transverse and face (edge) reinforcement can be defined. A number of pre-set styles are provided for quick access. Any number of new styles can be created by the user. The styles crated will be saved with the RCDC file and the configuration (*.rcps) file facilitating the use of these styles in other files.

4 Column & Wall Generation of Interaction Surface for axial force and bi-axial bending The computation of the interaction diagrams for members subjected to axial loads and biaxial bending has been enhanced. RCDC will now compute the actual interaction surface for all IS, ACI and EN code design. Columns will be designed and checked to ensure that the actual resultant bending moment in a given load combination will be within the moment capacity of the column for the axial load in the said load combination. The approach will replace the earlier interaction ratio based design that was required computation of the interaction curves for two orthogonal axes only. Column & Wall Design and detailing of columns of any shape Columns of any shape regular or otherwise can be designed and detailed in V5. Facility to define the shape has been provided in RCDC. Alternatively if the section designer has been used in analysis to model the exact shape of the section RCDC will import it.

5 Column & Wall Treatment / Detailing of connecting walls as a single entity Shear walls that are connected to each other creating a combined wall, will be identified and treated as a single entity for design, detailing and drawing. RCDC will identify the consolidated geometry, detail the junctions and create a single design and drawing. Column & Wall Computation of actual effective length factor for slenderness RCDC will compute the actual effective lengths for slenderness as per approach defined in annexure E of IS 456. The actual type of frame, whether sway or non-sway will be determined and respective graph used to compute the effective length factor. Similar rigorous procedure will be used for all other codes as well. The values computed by RCDC can be edited by the user if desired.

6 Column & Wall Option to detail walls with equi-spaced reinforcement When walls are detailed in RCDC zones are created. These zones have different spacing and potentials different rebars, with the spacing increasing from the outermost to the mid zone. This new option allows the user to maintain the same spacing of bars across zones. The rebars may change across zones but the spacing will be uniform. The length of the zones will be adjusted to ensure that the bar spacing in maintained. Column & Wall Optional check for Modulus of rupture for columns with axial tension The feature to check the modulus of rupture for columns with axial tension is now optional. User can set this option in the Design Settings form. Column & Wall Option to edit detailing and drawing settings from drawing forms This feature is available in all modules.

7 Beam Auto grouping at floor level in addition to across level grouping Auto-grouping feature has been introduced for beams. RCDC will identify sets of beams with similar spans, support conditions and reinforcement and suggest that these may be grouped. Beam Option to provide just 2 bars in zones with no bending moment The maximum bar spacing criteria apples to sections subjected to bending tension. At sections where there is no tension in any load combinations this check can be by-passed and only 2 rebars provided. This option is available in the Preferred Rebar Spacing window.

8 Beam Enhanced drawing options Footing SBC varying with footing width and plan proportions The feature to define SBC varying with the width and plan proportions of the footing has been provided. These can also be defined separately for various load combinations as per code specifications. Footing Design for columns with axial tension Columns with axial tension in any load combination will be designed as Pad footings. RCDC will size footings of columns with axial tension to ensure that sufficient counterweight is provided to counter the upward force. The top steel for such footings will be designed for bending considering the overburden and the surcharge. The shear checks in these combinations are performed at the face of the column. Footing Top Steel Options 1. Provide top steel as per depth of footings. This setting can be done in the General Settings Window 2. Top steel can also be provided for selected footings by selecting the option from the Design Settings form during redesign.

9 Footing Buoyancy, sliding and overturning checks Buoyancy, sliding and overturning checks can be separately defined. The load combinations for which each of these checks need to be done can also be uniquely defined. Pile Caps Pile Shear Capacity Check
