Research Progress and Trends in Fire Resistance of Large-Span Spatial Structures
摘要
Abstract
Under fire,large-span spatial structures may experience local damage and overall collapse.With the acceleration of urbanization,large-span spatial structures are increasingly used in various large-scale buildings,fire safety issues have attracted much attention.In recent years,scholars worldwide have focused on fire resistance of large-span spatial structures and conducted in-depth research on the fire response and design methods for different structures,achieving many representative results.In this paper,the main progress in fire resistance research on large-span spatial structures in terms of experimental research,numerical analysis,theoretical analysis and performance-based design is elaborated.Then,existing deficiencies in complex configuration designs,new material properties,simplified analysis methods and refined experimental plans are pointed out.Prospects are discussed for refined structural simulation models,improved design methods,intelligent monitoring and early-warning systems.Finally,key scientific and academic problems requiring further study are proposed,providing a reference for fire resistance design of large-span spatial structures in China.关键词
