框架楼房爆破定向倾塌的数值模拟研究

The Numerical Simulation's Discussion of the Structure(Building's) Orientation Incline While Blasting

依据失稳原理,对钢筋混凝土框架结构楼房进行了有限元数值模拟研究,分析了框架结构体的炸毁高度,并对框架楼房的稳定性进行了分析,讨论了定向爆破时框架楼房的重心外移问题和倾覆力矩问题,对框架楼房的爆破拆除有一定的借鉴作用。

The numerical simulation of the finite element are carried out to study the structure building of reinforced concrete frame according to the principle of losing steady. The blasting height of the structure building and the stability to the frame building are analyzed. The moving question and the moment question outside the center of the frame building are discussed in orientational blasting. All of these provide a certain reference to the demolition of the frame building.
