| 中文摘要: |
| 我国某些城镇地区,底部框架砌体结构仍然大量存在。这类结构大多呈现出一种"下柔上刚"、"头重脚轻"的结构特性。这种弱底层结构,在地震作用下抗震性能往往表现很差。本文采用有限元分析软件,对一典型底部框架砌体结构进行分析,研究其在地震作用下的抗震变形。根据计算结果,对该结构采取两种加固方式。通过比较得出,在结构底部增加抗震墙的加固效果要优于增加框架梁截面高度,且使得楼层位移减小更加明显。 更多还原 |

| Some urban areas in China，the bottom frame masonry structure still exists. This kind of structure has a structural feature of "the above stiffness is bigger than underside"，"the above weight is heavier than underside". The seismic performance of weak underlying structure under the earthquake is often well poor. In this paper，the finite element analysis software is used to analvae the deformation under the earthquake. According to the calculation results，it takes two reinforcement measures to the structure. Through the comparison，we can obtain that the reinforcement effect of increasing seismic wall is superior to increasing the frame beam section height and the displacement decreases more obviously. |
