【Abstract】 Studies on buildings and structures subjected to aircraft impact have been of greater concern,because malicious aircraft crash is one of the major means adopted in terrorist attacks due to the disastrous consequences and extremely bad influences involved.As the aircraft impact is related with multiple scientific issues,in this paper,the latest developments in the study of buildings and structures subjected to aircraft impact at home and aboard are summarized from three respects covered by test study,theoretical analysis,and numerical simulation,with special focus on difficulties and problems in research as well as the future research direction and trend,including firstly the system research and validation for scale model test,secondly the impact force model and local damage calculation formulas research,thirdly the establishment of the refined model of aircraft,buildings and structures,fourthly the vibration characteristics of buildings and structures subjected to aircraft impact,fifthly the coupling damage effect of impact load and fire load,and finally the comparative analysis of results calculated by the general model and the refined model,decoupling and coupling method,and various numerical simulation programs.更多还原
