变壁厚矩形水池有限元分析及经济性研究

Finite Element Analysis and Economic Research of Rectangular Water Tank with Variable Wall Thickness

对于平面尺寸很大、池壁为竖向单向受力的钢筋混凝土矩形水池,工程设计一般对池壁采用变壁厚以达到节约造价的目的。依据工程实例通过对多个变壁厚矩形水池模型进行有限元分析,总结变壁厚池壁的内力特点。对变壁厚矩形水池进行经济性分析,总结矩形水池通过采用变壁厚降低造价的使用条件。

For the reinforced concrete rectangular water tank with large plane size and vertical unidirectional force on the tank wall,variable wall thickness is generally adopted in engineering design to achieve the purpose of cost saving.In this paper,the internal force characteristics of tank wall with variable wall thickness are summarized by finite element analysis of multiple models of rectangular water tank with variable wall thickness based on engineering examples.This paper analyzes the economy of the rectangular water tank with variable wall thickness,and summarizes the application conditions of the rectangular water tank with variable wall thickness to reduce the cost.
