The Pushover Analysis of R.C frames Based on SAP2000

摘要

The pushover analysis had been done for a R.C frame model, vertex displacement,base shear, appear order and development situation of plastic hinges of the model had been get in different steps of pushover analysis, The pictures of basal shear-vertex displacement and response spectrum displacement-accelerated speed had been studied. The analysis results show that ,the R.C frame model correspond with the seismic design principle of stronger column weaker beam ',and meet the seismic requirements of the first stage and the calculating resistance to collapse of the second stage.
