Making a Time History Animation Video

Time history analysis solves for normal analysis results (joint displacements, member forces, code checks, etc.) based on loading that varies with time. For some analyses it may be useful to view an animation of the deflected shape of the structure as a function of time. This blog topic serves as a...

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...
