Making use of the double control damage criterion and index, the evaluation theory and the collapsemechanism of the structure are put forward.
利用双重破坏准则,确定了结构地震破损度标准,提出了建筑物倒塌破坏的评估理论与方法。

Two real buildings are analyzed to study the failure mechanism of the structures. The models proposed are helpful to study the collapsemechanism of high-rise seismic buildings.
采用建议的数值模型对两个实际结构进行了分析,分析结果对研究结构在地震下的破坏倒塌机理具有参考意义。
3
The earthquake collapsemechanism of structures is discussed, and an earthquake damage model is proposed, in which the degradation stiffness ratio is used as a damage parameter.
