RISAConnection Version 8.0 now offers weak axis moment connections with beams framing into the web of a wide flange column. Previously, connections were only permitted to frame into the column flange. This additional feature will allow users to change the orientation of their wide flange column. This option currently applies to beam/column moment connections that […]

RISAFoundation now has the capability to consider seismic loading for retaining walls. The Mononobe-Okabe formulation has been implemented, though direct input of the maximum pressure at the top of the wall can also be defined to create the inverted triangular loading. For details on the Coulomb calculations and the variation due to the Seed & […]

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. […]
