The Research On The Performance-Based Strengthening Of Shangyu Administrative Office Building

Based on shangyu administration building reinforcement project,the author proceededseismic performance optimization of reinforcement under the more severe earthquake andthe rarely met earthquake, in order to acquire corresponding various reinforcement schemeswhich met the various performance levels and recommended the best solutions. First of all,the original structure model is established using finite element software, the author proceededseismic performance evaluation for the original structure with the pushover analysis undermore severe earthquake and rarely met earthquake at8degree, combined with the original structureof the submission process, the author put forward5kinds of reasonable reinforcement schemes,then respectively set up model and assess seismic performance for the structure afterreinforcement under rarely met earthquake at8degree. Finally the author used the interlayerdisplacement angle performance quantitative indicators to judge the seismic performance levelwhich could reached of structure after reinforcement, and compared their economy and easeof construction, recommended the best seismic strengthening scheme.
