应用有限元和DDA模拟框架结构建筑物拆除爆破

Applying FEM and DDA to Simulate the Demolition of Frame Structure

针对建筑物拆除爆破设计中失稳和倒塌范围，提出了采用有限元和 ＤＤＡ进行建筑物拆除爆破的 数值模拟方法，并以框架结构建筑物为例，进行了实例研究，得到了一系列有实用价值的研究成果。

According to the two key questions in the demolition of frame structure, the loss of stability and the collapse range, this paper proposes the methods of applying FEM and DDA to simulate the demolition of frame structures. As an example, a frame structure is studied in applying the above methods, and a series of useful results are gotten.
