RISA-3D has the capability to automatically generate seismic loads and wind loads per ASCE 7 as well as a variety of international codes.

The applied loads in a response spectrum analysis (RSA) are the applied masses times the accelerations in the response spectra. Each mode of vibration produces its own set of joint reactions.

The applied loads in a response spectrum analysis (RSA) are the applied masses times the accelerations in the response spectra. Each mode of vibration produces its own set of joint deflections.

If you are using the Director tool to take your RISAFloor model into RISA-3D, the program will automatically calculate Seismic Mass for the RISA-3D Seismic Load Generator.

In RISA-3D, there are many different applications that require you to define Member Type in your model including AISC 13th Edition steel design, Seismic Design and Concrete design.
