I am using the seismic load generator for the first time. Can you please verify that I have applied it correctly? This is a viaduct with a long through-truss span. CRT ped LL straight PRATT TRUSS w MBTA ELEV.std

Dear All, I am trying to consider vertical component of seismic load using National building code of Canada NBCC. I assume 70% of acceleration is vertical direction (see below), but I am getting errors. I would appreciate if you tell me where is the…

for Seismic design category A structure, 10% of story dead load is required to consider (refer 11.7.2 of ASCE7-05). Does STAAD apply 1% of story dead load as Seismic load or it will calculate as per prescribed procedure based on chapter 12~15 of ASCE7…

Hi Good Day! I would like to raise my concern in my STAAD model regarding the distribution of seismic forces. Currently, I can't find a way to achieve my desired mode shape which is translational for Mode 1 and 2, and torsional for Mode 3. Though I…

Hi, 1. Does STAAD take into account the ductile detailing provisions of CHAPTER 21 of ACI 318M-11, while arriving at the reinforcement area and stirrup area ?? 3. If those provisions are available, how does STAAD identify a SMRF or IMRF or OMRF in…

Hi, I am facing a problem with reference to the Staad pro v9i SS6. Please help in solving the same if its a known bug or a workaround is available. I have imported the load data for seismic in all 6 directions (+/-X,+/-Y, +/-Z ) This is a Z up model…

Good Day! Does anybody knows how to Load Seismic using SNiP Code? Using STAAD Generated Loads (Load Definition), what parameters shall be considered in loading seismic? Step by step procedure may help :) Thank you!

I am performing a seismic analysis of a 15m steel tower structure, which supports a large boiler at a height of around 10m. I am currently using the IBC code input parameters (S DS , S 1 etc.) where STAAD utilises the equivalent force procedure. The…
