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。
The anti-overturning of the attached air defense basement is an important issue in the construction of air defense basement. According to the structural performance and mechanics characteristics of the building, we analyze various possible failure modes of the frame building under the action of shock waves, and propose the principle of “breaking and failing safety destruction”, based on the stability of the high-rise building air defense basement under the action of the nuclear explosion shock wave proposed by Luo Wenbao. Sex analysis [1] establishes a stable calculation equation for the attached air defense basement under the frame structure under the action of shock waves, and proposes structural construction measures.
