• Staad.PRO Seismic Response Spectrum (CQC)

    Hi. I am working on a steel structure and i have some issues with the seismic loads. That are the flexure MZ diagrams for the pure seismic load case in X direction (longitudinal). It caught my attention the results for the beam element marked in…
  • Live Load Reduction in Seismic Load as per IS 1893 : 2016

    Hello Team, I've understood that certain percentage of live load (25% or 50%) as per live load intensity shall be considered for seismic mass calculation as per IS 1893 : 2016, But nowhere it is mentioned in this code, about live load reduction in seismic…

    Hi all, I need to check the seismic load definitions regarding to mass source and other load sources for the attached model for a steel tank 18m diameter and 16.1m height rested on the ground. thanks in advance, ............................…
  • Purpose of adding selfweight under seismic definition

    Hello forum, I have one doubt regarding defining the seismic weight / lump mass / joint weight under the seismic load definition. What is the purpose of adding selfweight under seismic definition as highlighted in attached image IMO, it indicates…
  • Defining seismic mass (weight) of area/floor loads. IBC 2006

    Hi I am using IBC2006 on a project and have a newbie question I have defined the seismic parameters and converted the nodal and member loads into *weights* to go with the selfweight that I need to. So how do I convert my floor/area loads into *weights…
