摘要
提出了一种新的板锥网壳结构计算方法———等代空间杆系法 ,通过能量法和等效刚度矩阵法确定等代杆件的等效面积 ,把板锥单元等代为腹杆和下弦杆系 ,与钢上弦杆 (或包括钢下弦杆 )构成为具有两种不同材料杆系组成的等代双层网壳 ,然后按空间桁架位移法计算其内力与位移 .该法计算简便并具有一定的计算精度 。
A new method for analyzing plate-cone reticulated shell - equivalent space truss system method is put forward. Based on energy method and equivalent element stiffness matrix method, area of equivalent member is attained. Plate-cone reticulated shell is equated to double-layer reticulated shell with two kinds of material members. The internal forces and the displacement of the shell can be calculated by space truss method. The method is simple and accurate, which can be applied for initial design of plate-cone reticulated shell.
