RISA-3D has two ways of automatically generating seismic-related Basic Load Categories (BLCs) which can be later referenced in the Load Combinations (LCs):   Creating seismic BLCs (ELX, ELZ, etc) from the Seismic Load Generator Creating seismic BLCs (SX, SZ, etc) from Response Spectra Analysis In addition to the automatic generated seismic loads, users can always […]

Due to the nature of seismic brace design per the AISC Seismic Design Manual, the design loads for a seismic vertical braced connection are not always based on the input loads or the imported load combinations from RISA-3D integrated model. Seismic vertical brace connections must consider several possible envelops of loading. This is necessary to […]

RISAFloor designs the gravity system and then integrates with RISA-3D to design the lateral system. Only the lateral members are taken from RISAFloor over to RISA-3D. The loading is automated in this integration so one of the most common questions is: what loads are transferred when switching from RISAFloor to RISA-3D? Below is the brief […]
