Dear All, Please your kindly help about this problem. I create a modeling of a building where the main and primary beams are having 8m span. The secondary beams are at the midpoint of primary beams. It means each beam in my modeling is 4m length…

Is there any way to automatically have Frame check the members for the amplified seismic load cases (i.e. Omega*E)? Given that the equations essentially replace rho with Omega, I think I could just change the pho in the load case generator, but I wondered…

I've been asked to provide seismic calculations on some mezzanine stairs. I built a model of the stairs in RAM Elements, but have been having some issues trying to confirm that it is running the seismic analysis correctly. Elements seems geared toward…

Dear All, Does StaadPro provide the seismic load definition based on IBC 2009 and or ASCE 7-10? I checked but I only found IBC 2006 (which refer to ASCE 7-05). And the default is using Zip Code to determine the Ss and S1, is this Zip Code based…

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…

Hi Sir, I have made the groups of beams and slabs that would help me to simplify the name of each members. Can you help me to check my UBC Seismic Load Command wheter is already correct or not? And the load combination also? Please your…

I know when I input seismic UBC/IBC seismic loads I should type Perform Analysis and Change after each load case. The problem is, I am using National Building Code of Canada to generate seismic loads in my model and STAAD Pro still gives me the warning…

Hi, I have spectrum loading data to be considered in STAAD analysis, the data table have acceleration (g) in both horizontal and vertical diretion vs. time periods. My question is how to deal with such issue as all the STAAD example showing horizontal…

In lieu of using the response spectrum analysis in RAM Elements could you use the X and Z multipliers under the generate tab to perform an analysis similar to equivalent lateral force procedure? Thanks, Scott B.

Hi, I am curious about a couple of things on the way STAAD handles response spectrum analysis, and below are my questions. I would be very glad if you can provide me some answers . I'm using build 20.07.05.15, by the way. Due to the client…

My question is regarding carrying out a response spectrum analysis in STAAD Pro. This is what I have done so far. I have set up the model in kN and METERS units. I have allowed for the joint weights in the form of udl loads on the beams in all three…

Hello, I am new to STAAD Pro and am pursuing a project on seismic design. I want to know whether I can have a simulation of the seismic design that I have created in STAAD Pro. The version is v8i. Moreover, I would like to know if STAAD Pro can help…

1.) I am using RAM Concept to model a seismic footing under a shear wall. This wall is carrying high seismic shear and moment but has relatively low axial load, so it is tending to overturn. One option is to make the footing larger and pick up nearby…

Does Staad have a option to design steel structure addressing the requirement AISC 341-10 (i.e. Seismic Provision of AISC 360)
