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 […]

RISAFloor is the RISA Building System’s floor design software which allows users to design with composite decks, elevated concrete slabs and more.  When paired with RISA-3D, the two create a complete solution for the analysis and design of multi-story structures, including two buildings on the same podium. Equivalent Lateral Force/Static Force Procedure After the definition […]
