Utilizing RISA-3D for Seismic Design of Concrete Walls
In RISA-3D we now have the ability to design concrete shear walls for seismic forces.
There are 3 main aspects to concrete shear wall design. We will explain them here.
- Pier Design: ACI 318-14 Section 18.10.8 defines the wall pier design parameters.
- Coupling Beam Design: ACI 318-14 Section 18.10.7 defines the coupling beam design parameters.
- Boundary Zone Design: ACI 318-14 Section 18.10.6 defines the boundary zone design parameters. Currently RISA-3D determines whether a boundary zone is required or not per Section 18.104.22.168.
These results are then condensed into a single code spreadsheet view complete with code checks.
For details on the calculations and the additional reinforcement checks please check out the Concrete Walls – Seismic Design topic in the RISA-3D help file.
