钢筋混凝土框架结构爆破拆除仿真分析

Simulation Analysis on Explosive Demolition of Reinforced Concrete Framed Structure

基于钢筋混凝土结构爆破拆除基本原理以及理论研究方面上的不足,通过ANSYS/LS-DYNA软件一系列简化求解对钢筋混凝土框架结构爆破倒塌过程进行仿真与计算机分析,并与实际爆破拆除工程进行了对比。研究发现模拟效果与实际吻合很好,利用ANSYS对建(构)筑物倒塌过程进行整体式模拟是可行的,可依据模拟结果预估结构倒塌过程和对周围环境的影响。

The explosive demolition theory of reinforced concrete structure and the shortcoming were discussed firstly,and then the ANSYS/LS-DYNA software was applied to simulate the explosive demolition process.Compared with an actual project,the numerical result was found to fit the actual explosive demolition process well.Therefore,it’s feasible and reasonable to simulate the demolition process of reinforced concrete structure by ANSYS software.The numerical result can be used to evaluate the environmental effect caused by the structure demolition.
