加气混凝土结构的刚度计算

Stiffness calculation of aerated concrete structure

借助大型通用有限元软件ANSYS,对加气混凝土屋面板进行数值模拟计算,主要分析了屋盖的水平位移、墙片远端的应变值。并通过经验公式计算出屋盖水平位移(y)i与空间作用分配系数(m)和屋盖的综合剪切刚度(GA)之间的关系。最后,通过模拟值与计算值相比较,加深了对配筋屋面板刚度性能的认识。

This paper analyzes the numerical simulation calculation of aerated concrete structure by the large-scale finite element software ANSYS, such as, the horizontal displacement of roof and the strain value of distal segment of wall; and calculates the relationship between horizontal displacement of roof（yl） and space effect distribution coefficient（m） and shear stiffness of roof（GA）. Finally,this paper deepens the recognition for the stiffness performance of reinforced roof through comparing the simulated values with calculated values.
