The collapse of structure under earthquake is the most important and direct cause of casualties. At present, structural collapse has become a hot research topic in the field of seismic engineering. With the rapid improvement of seismic theory level, the study of earthquake collapse has also developed rapidly. The present research status of structural collapse damage under rare earthquake was summarized, and the systematicness and uncertainty of structural collapse damage were emphatically analyzed. The main criteria and analysis methods of collapse damage at home and abroad are discussed in detail, and their advantages, disadvantages and applicability are analyzed. The research results show that strong randomness is one of the main characteristics of collapse failure of structures. The establishment of overall failure criteria and damage assessment methods of structures needs to fully consider the characteristics of collapse failure of structures. Restricted by the test conditions, the existing test methods cannot fully and deeply reveal the mechanism of structural collapse, and the definition of critical state of building collapse is relatively vague. The developed analysis methods can complete the collapse analysis of a certain structure, but it cannot avoid the problems caused by unfavorable factors such as random effects. Whether the method is suitable for the large degree of non-linearity or the collapse stage still needs further study. The development of earthquake collapse is discussed in order to provide reference for future research. |
