摘要

本文通过PKPM结构设计软件对三层砖混结构加固前后的抗震性能做了对比,并选取较为典型的底层抗震薄弱部位作为研究对象。研究了结构加固后结构抗震承载能力和弹塑性变形能力的改善程度,并对两种加固方法进行了比较分析。结果表明,两种加固方法对结构的整体抗震性能均有不同程度的提高。
Using the PKPM software,comparisons among the masonry buildings before and after retrofitting to improve the seismic performances was presented in this paper.Some weak locations on the first floor were chosen to study in very details.According to this research,it is shown that two different strengthening methods in this paper would enhance the seismic bearing capacity of the structure as well as its deformation capacity to some extent.Thus,both of them can be applied to the practical engineering.
