摘要(Abstract):
研究钢结构建筑爆破拆除工艺技术,选择DDA方法作为计算机模拟方法,叙述了钢结构爆破拆除计算机仿真软件的数据输入系统、预处理程序、静力分析或动力分析程序、图形后处理程序等的功能和流程。本文还对一个钢结构简例的爆破拆除进行计算机模拟,主要模拟研究了爆破缺口高度对倒塌效果的影响。
The technique for blasting demolition of steel construction is discussed in this paperThe Discontinuous Deformation Analysis Method (DDA) is adopted to simulate the processThe function of original data input system,the preprocessing program,the static or dynamic analyzing program and the graphic postprocessor is presentedA simple example is introduced to demonstrate the effect of the blasting cut height on collapsing condition
