• Modeling a Structure with Wall shear

    Hello, I hope you are very well. 1. Why when I make models with walls (modeled with plates) and I do a spectral modal analysis with the IS1893 2002 standard, the participating mass of the modes does not reach 90% quickly, I have to place about 200 modes…
  • RE: Problem in Response Spectrum Analysis by using IS 1893:1984

    Scale factor is a factor by which the input spectrum data is multiplied when carrying out a response spectrum analysis. Typically when the acceleration spectrum is in terms of “g” ( normalized values), you would use the value of “g” as the scale factor…
