A review on progressive collapse study for large-span space structures
摘要
Abstract
Large-span spatial structural systems have huge space volume and cover large open areas, thus in the event of unexpected loading the spatial structures may develop catastrophic progressive collapse, causing a large number of casualties and substantial losses. This raises the demand for studies on collapse of large-span space structures. Up until now, most of the published papers concerning about the progressive collapse focused on frame structures, for which reliable design methods and corresponding codes have thus been established. This paper gives an overall review on numerical analysis, experimental, as well as theoretical methods for the structural progressive collapse of large-span structures based on papers published in the literature and the authors' research work. A general discussion on the progressive collapse was first presented, followed by key techniques that may be adopted in numerical simulation, including the determination of discontinuous displacement field, impact-contact analysis, etc. Multi-scale computational methods and their implementation into collapse analysis were also included. Experimental studies on collapse of large-span structures were reviewed, with recommendations on key techniques including displacement measurement and initiation of failure. Collapse mechanism, evaluation of structure robustness and simplified assessment methods on large-span structures were also covered.关键词
