• in mass participation factor i need to increase the z direction value its not sufficient because its below 65% how to increase and i hve attached my model here

  • i have doubt regarding mass participation i got 65% in X direction and in Z direction 60% i couldn't increase in Z direction i have increased column size also even though i couldn't attain

  • time history analysis - mass participation with floor diaphragm

    When I specify a floor diaphragm in my time history analysis model, the mass participation in the x direction exceeds 100%. What is the issue behind this? Are my results reliable? If not, how do I work around the issue? Thanks! Time History - diaphragm…

  • Frequency Check between Structure and Paddle Mixer

    Hi, I really need you help on this problem. We have a paddle mixer with Frequency at 1800rpm. We have extended the existing structure to accomodate the paddle mixer. Now we run a frequency check and compared it with the limits of 80%-120% of the…

  • Seismic Loading

    Can someone please give me the STAAD input text for seismic to UBC and to BS EN 1998 - I find the STAAD help editor difficult to follow. I am assuming that I will use CQC for the modal analysis, but what about SRSS etc. In the example I have pulled…

  • RE: Response Spectrum Analysis and Base Shear

    First one comment. As part of the mass definition for the response spectrum load case 3, you should add the udl in the X direction as well as shown below. This is to ensure that vibration of masses in all possible directions are considered for the eigensolution…

  • STATIC AND DYNAMIC ANALYSIS OF STRUCTURE

    Please share a realistic example of seismic analysis using STATIC and DYNAMIC inputs in a single run and explain why the said model is now ready for design (like the mass participation ratio in dynamic analysis is now accepted and show also how to scale…
