Seismic Design of Concrete Walls using ACI 318-14 Chapter 18 now Available


In RISA-3D we now have the ability to design concrete shear walls for seismic forces.

Seismic Design of Concrete Walls1

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.
Seismic Design of Concrete Walls2
  • Coupling Beam Design: ACI 318-14 Section 18.10.7 defines the coupling beam design parameters.
Seismic Design of Concrete Walls3
  • 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 18.10.6.3.

These results are then condensed into a single code spreadsheet view complete with code checks.
