摘　　要：针对传统机场建筑结构防灾性能分析方法存在动力加载性能较差且耗时较长的问题,该文提出一种机场建筑结构防灾性能分析方法,首先获取机场建筑的具体建筑结构数据,对机场建筑结构进行网格划分与灾害区域计算,从而构建机场建筑结构的FDS信息文件。然后对机场建筑结构进行灾害模拟,根据模拟结果得到机场建筑结构灾害下的荷载传递,从而获取机场建筑结构灾害传力途径,在此基础上构建机场建筑结构灾害动力响应模型,对机场建筑结构实施动力响应分析,实现机场建筑结构防灾性能分析。In view of the problem of poor dynamic loading performance and long time-consuming in the traditional airport building structure disaster prevention performance analysis method, we propose an airport building structure disaster prevention performance analysis method. First, obtain the specific building structure data of the airport building, grid division and disaster area calculation of the airport building structure, so as to build the FDS information file of the airport building structure. Then, the disaster simulation of the airport building structure is carried out. According to the simulation results, the load transmission under the disaster of the airport building structure is obtained, so as to obtain the way of the disaster transmission of the airport building structure. On this basis, the dynamic response model of the airport building structure is constructed, and the dynamic response analysis of the airport building structure is carried out to realize the disaster prevention performance analysis of the airport building structure. Finally, a comparative experiment is set up. The results show that the dynamic loading performance of this method is better, and the experimental time is shorter, which can effectively achieve the analysis of the disaster prevention performance of airport building structure.
