摘要
在试验研究的基础上,就采用填充抗震墙或带框钢支撑加固含有薄弱层的RC框架的实用抗震验算方法问题,提出了采用改进的楼层综合抗震能力指数的方法,并给出了楼层受剪承载力的计算公式。按本文方法计算的楼层综合抗震能力指数、楼层受剪承载力与模型试验及有限元分析的结果相吻合。还给出了填充抗震墙、带框钢支撑与原有框架构件连接构造示意,使两项加固技术进入了实用设计阶段。
Based on the test results, practical seismic checking and calculation methods were studied on the RC frame with weak story strengthened by filling seismic shear wall or steel frame brace. The advanced story integrated seismic capability index method was put forward and the calculation formula of story shear bearing capacity was also given. The results of story integrated seismic capability index and story shear bearing capacity calculated according to this method quite agree with those of tests or FEM numerical analysis. The connection details of the filling seismic shear wall, steel frame brace and existing RC structural members were given, which means that the two seismic strengthening techniques can be used in practice.
