In my etab model, I have defined two grid systems; first grid at 0 degree angle and second grid inclined at 45 degree angle. To consider eccentricity effects, I am displacing mass of the structure by 5% in x and y direction. But I am confused as to which grid system will etab displace the mas...

I am involved in project where I urgently need to have good answers to following questions related to response spectrum analysis for my clear understanding and to assert to client that my approach is right. I am not designing shear walls under RSA load cases but only for static cases. Scale fac...

I am not getting this statement , that how to check torsional irregularity . Please Help . "Torsional irregularity shall be considered to exist when the maximum story drift, computed including accidental torsion, at one end of the structure transverse to an axis is more than 1.2 times the average...

Hello everyone!! I have tried to understood the every step of etabs analysis for simple two story irregular building by manual calculation. But i got stuck when the centre of rigdity and the amount of torsion does not match. How can we calculate these things manually? . As well as i want to know fu...

Some one asked me abt dynamic analysis and when we need to perform dynamic analysis and what about seismic irregularities and how to base our design on that. I couldnt reply but right now there is power shut down in my office (im enjoying it). So thought to share the reply on sepakistan.com so its...
