【摘要】 结合震害调查与经验总结,通过选取具有一定代表性的八个多层现浇混凝土框架结构电算模型,探讨了楼梯对多层框架结构的整体刚度和层间位移角的影响,研究中发现:楼梯的斜撑作用使得多层框架的实际刚度有所增加,在结构设计工作中应在建模时尽量模拟实际状况考虑楼梯斜撑对结构的影响。更多还原

【Abstract】 Combining with the investigation of earthquake disasters and the experience summery,the paper explores the influence of stairs on the general stiffness and the angle of floor displacement of multi-floor frame structure by selecting the electric accounting model of some representative eight multi-floor cast-in-place concrete frame structure,and finds that the sprag can increase the factual stiffness of the multi-floor frame,and the sprag of stairs on the structure should be considered in the simulation of the model in the structural design.更多还原
