abstract
The determination of seismic demands on a structure are based on several assumptions concerning the structural parameters and modeling. The response of any structure depends on careful selection of those parameters so as to capture the significant effects of the structure. The focus of this study is to evaluate the effect of selected parameters on the demand estimation of a controlled structure under severe seismic demands. The parameters investigated here are: 1) the level of nonlinear modeling and analyses of the structure, 2) the initial stiffness of the structure, and 3) the strain-hardening assumptions in force-deformation relationships of the elements.
