• 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…
  • Response Spectrum Analysis & Design Forces Problem for Shear Wall Design in RCDC

    Hi everyone, I have faced a problem importing analysis forces from Staad Pro to RCDC for a shear wall example. I have performed seismic analysis by using the response spectrum method for a box-shaped and cantilever shear wall in StaadPro. I can determine…
  • No uplift while doing Response Spectrum Analysis

    While analyzing a structure for response spectrum seismic loading the response(base reactions, member end forces, etc.), comes to be in absolute value. This is due to the fact that the responses coming out of several modes are combined by using some predefined…
  • What is the reason for designing of column without considering the worst load case even though I add several load combinations?

    In my model I analyze and design a G+8 RCC Structure, and the column is designed for only the first load case even though other load combinations give maximum axial force and moments. I attached the screenshots of output file below.
