无梁顶盖圆形蓄水池目前仍被广泛采用。当考虑壁与盖或壁与底为弹性联结时,重要的是先算出联结处的弯矩。过去,借助于结构力学中的力法原理计算这些弯矩,需求基本体系的各种变位,然后解含有未知力的位移方程,计算较繁。应用弯矩分配原理能使计算工作得到一定简化,而其精确性可与前者相当。本文先通过对等截面池壁的分析,说明弯矩分配原理、计算公式和计算算例。再导出变截面池壁时的公式。一、主要符号和计算前
No beam cover circular reservoir is still widely used. When considering the wall-to-lid or wall-to-bottom elastic coupling, it is important to first calculate the bending moment at the joint. In the past, with the help of the principle of force method in structural mechanics, these moments were calculated, various displacements of the basic system were required, and then the displacement equation with unknown forces was solved, which was calculated more frequently. The application of the principle of moment distribution can make the calculation work a certain simplification, and its accuracy can be comparable with the former. In this paper, through the analysis of equivalent section cell wall, the principle of moment distribution, calculation formula and calculation example are described. Then derive the formula of variable section pool wall. First, the main symbols and calculations before
