框架结构附建式防空地下室抗倾覆问题的探讨

Discussion on the Problem of Accessorily Built Air-raid Basement with a Framework Resisting Overturn

附建式防空地下室抗倾覆是防空地下室建设中的重要问题。根据建筑物的结构性能和力学特点 ,针对框架建筑在冲击波作用下的各种可能破坏形态进行分析 ,提出“断融安全破坏”原则 ,依据罗文豹提出的核爆炸冲击波作用下高层建筑防空地下室的稳定性分析[1] ,建立框架结构下的附建式防空地下室在冲击波荷载作用下的稳定计算方程 ,提出结构构造措施。

Accessorily built air raid basement with a framework is an important question of the air raid basement construction. According to the function of the structure and the mechanics characteristic of the building, the principle of break melt safely destroy is presented by analyzing every possible destroyed patten of the structure with a framewok. According to the document 1, in this paper the stability calculating equation of accessorily built air raid basement with a framework under the load of shock wave is set up, and some measures to bulid structure are put forward.
