| 摘 要： | 阐述了中国抗震设计规范的多次变化和在不同时期建造的砌体房屋在抗震性能上存在的差异.选择西安市20世纪90年代初期低洼棚户改造工程中有代表性的6层砌体结构住宅作为研究对象,用不同抗震规范对该房屋进行抗震计算和分析;指出墙体局部尺寸过小,大洞口两侧没有构造柱加固,墙段水平剪力分布不均与构造柱、圈梁数量及配筋率偏低等抗震薄弱环节,最后提出了解决小墙段抗震承载力不足问题的方法.

| Abstract: | Many changes of code for seismic design of buildings were discussed,and the differences of performance for masonry structures in the different periods were pointed out.Meanwhile,authors analyzed the representative six stories masonry structures house that was the research object in low-lying shanty's improvement project in the beginning of 1990s in Xi'an.Authors found that the local size too small,no metabolite reinforced big hole,unsymmetry shearing force of level,the number of metabolite and ring beam and reinforcement too low were the weak links for seismic.Finally,the methods of improving the seismic capacity in small wall were presented. |
