摘要
介绍了现浇钢筋混凝土空心无梁楼盖结构体系的原理、边支承空心楼盖设计原理、刚度计算等方面的问题.依据规程CECS175[1]“当空心楼板顺筒、横筒两个方向的弹性刚度相差不超过10%时,可忽略楼板的各向异性,取与普通实心楼盖相同的内力分析方法”的规定,对边支承楼盖设计在PKPM软件中的实现进行了分析探索,提出了可以在PKPM软件中将空心板按等厚实心板计算的设计思路和方法,并绘制相关表格供设计人员参考.
This paper introduces the design principle of cast -in -situ reinforced concrete hollow floor, the design method of side supporting hollow floor, stiffness account and so on. Based on the stipulation in CECS175 , when the phase contrast between the stiffness along the tube filler and vertical the tube filler does not exceed 10% , the aeolotropism of the floor can be neglected and the same inner force analysis might be used. How to realize the design of side supporting hollow floor in PKPM software is analyzed. The design method that we can compute hollow floor as solid floor in PKPM is put forward. Related table is also presented as references for designers.
