一、引言在1968年十胜冲地震中,由于建成后没有几年的建筑物也受到了严重震害,因此,普遍要求对现有钢筋混凝土建筑的抗震性能进行重新分析。根据调查结果发现,现有钢筋混凝土建筑物的抗震性能有相当大的分散性,并认为其中有些建筑物需要进行抗震加固。二、关于抗震加固方法问题在现阶段,由于对现有建筑物各种加固方法的加固效果、施工方法、经济效果等有关资料还很不够,因此,为了选定合理的加固方法,目前正在进行各种试验研究。
I. INTRODUCTION In the 1968 Shishengchong earthquake, due to severe earthquake damage to buildings that were not completed for several years after completion, it is generally required to reanalyze the seismic performance of existing reinforced concrete buildings. According to the survey results, it has been found that the seismic performance of existing reinforced concrete buildings is quite decentralized, and some of these buildings are considered to require seismic strengthening. Second, on the issue of seismic reinforcement methods At this stage, due to the existing buildings are various methods of reinforcement reinforcement effects, construction methods, economic effects and other relevant information is still not enough, so in order to select a reasonable reinforcement method is currently ongoing Various experimental studies.
