Video: Using Various Diaphragm Types in RISAFloor

RISAFloor supports the three fundamental types of diaphragms used in structural analysis: rigid, semi-rigid and flexible. Watch this video to learn how to consider each of these diaphragm types within the same model and same floor plan.

WEBINAR: Design of Cold-Formed Steel Buildings in RISA

More and more, commercial buildings are being designed as combined-use structures that handle everything from parking and retail, to apartments and other living spaces. With these requirements, structural engineers are asked to provide a safe, strong and non-combustible framing system that can also achieve the desired overall building height. Combining non-combustible materials such as cold-formed steel with masonry and hot-rolled steel results in higher building heights for these structures at an economical price. The RISA Building Suite now includes robust features aimed at designing these building types that rely heavily on cold-formed steel. In this webinar, attendees will: Understand the benefits and efficiencies of using cold-formed steel for multi-story buildings Learn to layout a multi-story building utilizing cold-formed steel walls, hot rolled steel framing and masonry walls using RISAFloor. Learn to design cold-formed steel wall panels for gravity and shear loading according to appropriate building codes with RISA-3D. To register, click the button below: Register Tags:…

What Loads Transfer from RISAFloor to RISA-3D?

RIAFloor 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 explanation to answer this question. Gravity Loads: The lateral members that become part of the RISA-3D model bring over their gravity loads. This also includes the beam reactions from the gravity only members that were not transferred in to RISAFloor. The load categories in RISAFloor are automatically converted into Basic Load Cases in RISA-3D. The exception to this are the Load Categories that deal specifically with construction loads (DL Const and LL Const), which are not converted. Wind Loads: The wind loads are automatically calculated as the RISAFloor model gets integrated into RISA-3D. The wind load parameters are located in the Wind tab of the Global Parameters in RISAFloor. However, these settings may also be changed when the wind load dialog pops up when transferring to RISA-3D: The option to generate roof wind loads are only present in RISA-3D models that are integrated with RISAFloor…
