摘要
使用等代框架法或经验系数法计算无梁楼盖时,不易确定倾角托板柱帽的刚域长度,进而影响等代框架法中支座弯矩控制截面的选取以及经验系数法中净跨长度的计算。本文引入近似柱比法解决此问题,并辅以算例计算,可为使用等代框架法及经验系数法计算无梁楼盖提供一定的参考。
In the design of flat slab structures,it is difficult to calculate the rigid zone length of tapered columncup with support plate,which would effect the calculation of clear distance in direct design method and the moment section in equivalent frame method.An equivalent column analogy method is used in the paper to solve the question with some examples,in order to provide convenience to structure designers.
