Help!

hi, ETABS professional:
Another questions to add on;

a) I'm testing with seismic loading.. How come the maximum displacement is increased after i add on Shear Wall? Suppose to be decrease right? What has gone wrong?

Thanks so much.

depends, if you're adding lots of mass in a rather small shear wall then your shear resistance capacity will be overcome by your extended inertia forces.

JV91:

If your shearwall layout is not balanced, then you could be CAUSING ADDITIONAL TORSION and your model could twist more than it did before the new shearwall.

Thanks!
