Abstract
The purpose of this thesis was to study the pushover analysis in software of Sap2000 almost distributed the base shear in fixed proportion. In order to press close to the result of nonelinear dynamic analysis when the floor bearing the earthquake force is yielding,we changed the load distribution proportional to displacement in sequential steps to simulate the dynamic response.So we writen fixed distribution codes and modified distribution codes by using capacity spectrum method to get the ductility of every floor and ground acceleration when whe building is faulire.And we compared the fixed distribution with the modified distribute.At last,we run the dynamic analysis to verify the nonlinear stastic analyses.
In the analysis,we created different floor of the building models to change period,and the floor of the building used the single particle to simplify simulation to analysis,then linking the particles by nonelinear and bilinear linking type we called stick models.Building designs in general, its higher floor may be over designed. A building is larger, its stiffness after yield is larger.So we used several parameters to estimate which model is sensitive by modifying the distributed load.
