Dear Silvia,

How can I specify correct rayleigh coefficients for a ten story concrete building with moment resistant frame?
by the way, the building does not have any dampers.

Hi silvia i have modeled a one story building which has one bay in each direction. i want to do pushover analysis.unfortunately i get different reaction in each base. and the sum of the base reactions are much more than base shear according to Etabs model. wipe model basic -ndm 3 -ndf 6 #######Units...

Hi silvia, i have modeled a 1 story building which has one bay in each direction.I want to make diaphragm rigid. I create a point in the center of mass and use rigidDiaphragm command to joint all other nodes to that point. like : rigidDiaphragm 3 105 101 102 103 104 i get different results when i us...

i have never worked with building tcl. where can i download it? I correct some mistakes, but pushover analysis stops in 43th stage in y direction and 38th in x direction. there are narrow difference between x direction result and y direction result that is not sensible can i send you my code, and wa...

Dear silvia I have modeled a 10 story symmetric RC building.when I want to run pushover analysis i face some problem. 1)although building is symmetric, i get different period for 1st and 2nd mode 2)when i want to push in x direction, it fails and can not reach maximum disp. (Error : fail to get comp...
