摘要:
国内外的高层民用建筑及多层的工业厂房多为框架结构。当火灾发生时,框架结构会发生连续性倒塌的现象,造成大量的人员伤亡及经济损失,已成为威胁公共安全的重要问题。本文概述了国内外受火后钢框架结构和钢筋混凝土框架结构连续性倒塌的研究现状,对直接与间接设计方法进行了区分,对各种设计方法的适用情况作出解释,并从单个构件到整体抗连续性倒塌性能的角度进行数值模拟以及试验研究分析,用试验成果验证理论的正确性,为后续的结构设计提供设计依据。最后,对框架结构连续性倒塌的发展态势进行展望。
Abstract:
High-rise civil buildings and multi-storey industrial plants at home and abroad are mostly frame structures. It has become an important issue that the frame structure may collapse continuously when the fire occurs, which can cause a large number of casualties and economic losses and threaten public safety. A summary about progressive collapse of the steel frame structure and reinforced concrete frame structure after fire was concluded in this paper. The direct and indirect design methods were distinguished, and the application of various design methods was explained. In addition, the numerical simulation and experimental researches were carried out from a single component to the overall resistance to continuous collapse performance. The test results were used to verify the correctness of the theory and to provide a design basis for subsequent structural design. Finally, the development trend of progressive collapse of frame structure was discussed.
