Hi IJR, thanks a lot fot the helpful advice...I will try and let you know then.. thank you s3ndy

Hi Ijr, Thanks for the explanation. It s vertical bracing system. Say for wind or floor weight, I can run as nonlinear static case. But how about moving load? Traffic loading (moving load) will go into my bracings. Can I set the moving load as non linear static case as they are two different...

Dear All, I have some quiries on the SAP moving load and non linear analysis case. Can SAP do non linear moving load analysis case? I have a steel frame with bracing member subject to traffic loading. I assign the bracing as a tension member only and run non linear analysis. But in SAP,what I...

Hi Willis, thanks, can you tell me how to how to define the non linear analysis for my case. Thanks a lot

Hi all, I am modeling a box section (frame elements) which sit on the soil. In SAP 2000 I assigned a line spring (I used subgrade modulus for the spring constant) to the element at the base (base of box section). I meshed the line into a few elements and I chose the ‘compression only’ option in...

Hi zeemas, I have rerun my ETABS model and it gives me reliable base shear result. Thanks for your helpful advice. The story mass at 8-story podium) becomes much smaller that that in the previous model (when rigid diaphragm was still applied)...What is the reason?

Hi zeemas, thanks for the reply. Now I am still rerunning my ETABS model using the flexible(semi rigid) diaphragm at the podium story. How to obtain the response spectrum base shear in ETABS? Should I use the value given in the 'building modal info > RS base reaction' or 'display > story...

Hi everybody, I created a ETABS model of 40-story building with 8-story podium, analyzed with response spectrum case and tried to find out the response spectrum base shear. Should I use the value given in the 'building modal info > RS base reaction' or 'display > story shears (at base)' because...
