"Nonlinear Static Analysis (push-over analysis) and its Applications on the Effect of Improving Soft Soil on Increasing the Performance of Seismic Resistance Concrete Frame"

This research includes the procedures of applying the nonlinear static analysis (pushover analysis) on seismic resistance concrete frame systems by modeling the foundation system (soil + footing) down the structure as an elastic springs and rocking stiffness and comparing them with premise of fixed support in terms of the deformation and displacement, load and stress distribution in frame elements and accordingly clarifying the effect of improving soil on foundation system stiffness and on the responding of frame to lateral loads which helps in moving the structure performance from low level to a higher level that we need from structure to reach following the design strategy that we choose for the structure.
