Dear all, I am trying to design shearwalls through ETABS with temperature load applied over shell. At various location, spandral section fails in Shear due to temperature and piers (sometime in shear, mostly in flexure). (See Attached Image) Certainly all the problem in Shearwalls are due to temperature. I don't want to increase cross section of spandral or pier at some location just due to temperature load case as it will appears non-uniform with rest of the wall. I have seen stiffness modifier affect distribution of forces and also rigid/semi rigid daiphragm assumption. Can anybody guide how to properly design the shear wall with temperature load applied in ETABS or share any similar experience. Thanks in Advance.

Hi Abid, I am not clear about your first question. For your second question, please see the attachment. Ritz analysis vs Eigen Analysis.pdf Cheers!

welcome yaseen!!!admin will work on this if it will be feasible forum will be available at tapatalk. forum is available at facebook page "https://www.facebook.com/SEFP.Pakistan/?fref=ts" check if you can access it from your android.

For braced frames, the beams are intentionally kept pinned as you don't need to have a moment connection for load transfer as brace takes care of it.

Otsruc.com is very good site to learn structural software ETABS/SAFE/SAP etc. developed by esteemed fellow Rana Waseem he is very good practicing structural engineer with excellent command on software. Along with joining courses you have to work with the software and only software is not the structural engineering you must work on the basics of structural engineering. Just modelling on software and getting results is not engineering. this exercise can be easily done by a matric pass student as well if he is trained to use the software. Engineers are required to grasp knowledge behind the software. Engineering judgment comes with practice and working under kind seniors who guide you through the design process. All young engineers are suggested to be attached with seniors and request them to guide and mentor you through the process. And seniors are requested to mentor at least 1-5 freshers:-)
