| 摘 要： | 针对中小学砌体结构教学楼的受力特点,提出横墙和开洞纵墙的等代框架模型,分析了模型的抗弯、抗剪和轴向刚度计算方法;结合国内外对钢筋混凝土结构性能水平的划分标准,将砌体结构的性能水平划分为正常使用、中等破坏和生命安全三个阶段,并通过对大量砌体墙片试验数据的统计,得出其各性能水平对应的层间位移角限值。最后利用所提模型对一砌体结构教学楼进行Pushover分析,将其实际层间位移与所提性能指标进行比较,结果表明结构在不同地震水平下均满足预定的性能目标。

| Abstract: | The equivalent frame model of cross wall and longitudinal wall with holes are proposed based on stress characteristics of masonry structures for primary and middle school buildings,and calculation methods of bending rigidity,shear resistance and axial stiffness about the model are analyzed.Performance levels of masonry structures,combining with division standards for the levels of reinforced concrete structures at home and abroad,are divided into three levels with corresponding story drift angle limitation ... |
