Performance Based Assessment of Seismic Response Factor for SMRF Staging Elevated Water Tank
RC staging water tanks are essential facilities that are expected to remain operational even after sever earthquakes. The seismic design codes/standards of most countries incorporate the nonlinear response of a structure through a ‘seismic response factor’ (R). This factor permits a designer to use a linear elastic force based design while accounting for nonlinear behavior and deformation limits. In this paper orderly approach is deputed to determine the seismic response factor of elevated water tank having different soil flexibility. For nonlinear static pushover analysis finite element method is used. The capacity curve of each model is generated and the ‘R’ factors are obtained such wise. The impact of soil flexibility on seismic response factor of RC framing tank is evaluated. ‘R’ factors are determined for existing tanks at two performance level.
