摘要
采用滑动支座对RC框架楼梯模型进行改进,通过模型低周反复荷载试验及有限元分析验证改进措施的有效性。最后提出该构造措施可以应用于其他形式楼梯的设计建议,并对日本的两种处理措施进行分析评述,可对今后规范和标准图集的修订提供帮助。
An improvement measure named slipping-foot was adopted for the staircases of RC frame structures. The measure was wrified to he effective by the low-cyclic reversed loading test and finite element analysis. It is recommended that the slipping-foot mcasure can be applied in other types of staircases. Two improvement measures used in Japan were analyzed and discussed. It can provide reference for the revision of code and standard atlas.
