When modeling building structures using steel or composite steel floors, engineers typically utilize rigid diaphragms to distribute lateral loads (wind and seismic) to lateral load resisting elements such as shear walls, moment frames and braced frames.  Rigid diaphragms represent a plane of very high rigidity and distribute load to elements which connect to them solely […]

When using semi-rigid diaphragms in a RISAFloor/RISA-3D model, it is possible to see negative moments at the ends of pinned beams as a result of the link between the semi-rigid diaphragm and the beam-column connection. In RISAFloor, semi-rigid diaphragms utilize internal rigid links to create a 12in by 12in “rigid zone” around the column location […]

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 […]
