Continuous Beam/Slab Design
Design and detailing of reinforced concrete beams and slabs. Cross-sections can include a combination of rectangular, I, T and L-sections, and spans can have constant or tapered sections. You can design a single span (simply supported, fixed or cantilever) or many continuous spans. Spans can be supported on with or without rotational restraints, e.g. columns below and/or above.
The design calculations incorporates automated pattern loading (of dead and live loads). At ultimate limit state, moments and shears can be redistributed to a user specified percentage. Both short-term (elastic) and long-term deflections are calculated. The long-term deflection calculations take account of concrete cracking, shrinkage and creep. For beams and one-way spanning slabs, you can manipulate long-term deflections by editing the steel reinforcement.
Frame Analysis also provides a convenient way for generating input for this program. When you model a building structure, you can use the design links function to select a series if beam elements and export the analysis results (geometry together with the bending moment and shear force envelopes) to Continuous Beam/Slab Design.
You can generate complete bending schedules (main bars and shear reinforcement) for beams and slabs. A 3D picture helps you position the bars accurately and identify conflicts. The program automatically adjusts the reinforcement detailing rules according to the mode selected, e.g. beam or column strip of a flat slab. Using the rebar editor, it is easy to modify the main and shear reinforcement -- diagrams display the entered reinforcement together with the required amounts at ULS and minimum amounts required by the design code. You can open the generated bending schedules in Padds or Probar 2D for final editing (if needed) and printing.
