某钢筋混凝土水池破坏过程模拟与分析

Damage analysis and simulation of a RC water pool

本文采用数值分析方法对某实际钢筋混凝土水池破坏过程进行模拟与分析,探讨了其发生破坏的主要原因。首先,采用SAP2000软件对该钢筋混凝土水池进行弹性承载力分析,计算结果表明该水池中间拉结钢筋混凝土系梁配筋严重不足,存在安全隐患;其次,基于LS-DYNA软件对该水池进行非线性破坏分析,结果表明,由于中间系梁的受拉承载力不足,系梁发生断裂最终造成整个水池变形过大而发生破坏,模拟结果与实际破坏结果相符。

In this paper, progressive damage simulation of an actual RC water pool wascarried-out by using numerical computing method. The key failure reasons of this pool were discussed. First, elastic analysis of the pool＇s carrying capacity was studied based on SAP2000 software. The results showed that the connected beams in the middle were far more lacking with reinforcement areas. Then, nonlinear damage analysis was also issued for this RC pool by using LS--DYNA software. The analysis told that the connected beams in the middle were broken first for lacking of carrying capacity. The whole pool ended in failure due to large deformation. The simulated results were coincident with the actual accident.
