The methods used to improve mass participation in model are essential for understanding and conducting a proper response spectrum analysis in RISA-3D. Read More
RISA-3D allows users to import recorded seismic ground motions for use in time history analysis. Read More
When creating a Time History function for sinusoidal equipment loading the program can automatically adjust the force and frequency at the beginning and end of the time history function. Read More
RISA-3D v14 introduces Time History analysis for use in the dynamic solution. Read More
RISA-3D allows users to view an animation of the deflected shape of the structure as a function of time. Read More
RISA-3D v13 includes a new Ritz Vector Solver for the Dynamic analysis. Read More
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. Read More
