Integrated Building Design
RISAFloor, RISA-3D, RISAFoundation and RISAConnection are so tightly integrated they operate as one program on the same building model. Optimize the gravity system in RISAFloor, the lateral system in RISA-3D, the connection design in RISAConnection and the foundation system in RISAFoundation, with a free and complete flow of information both ways.
Integration supported for the following versions: RISA-3D v22, RISAFloor v18, RISAFoundation v16 and RISAConnection v14
Gravity loads are automatically applied & updated
Lateral models created as you define & change floors
Detailed reports for Wind and Seismic load calculations
Combine all gravity and lateral loads in standard load combinations which can be edited by the user.
All member end forces are automatically updated and sent to RISAConnection for complete connection design
All reactions (columns and walls) are automatically imported into RISAFoundation for design and detailing of the foundation system
Rigid & flexible diaphragm analysis and wood diaphragm design
