模块化钢结构关键构件与结构整体性能研究进展
Research Advances on Behavior of Key Components and Overall Structure of Modular Steel Structures
摘要
Abstract
Modular steel buildings represent an emerging structural system composed of factory-fabricated,self-contained modular units that are assembled on-site.Owing to their standardized production processes and flexible assembly methods,they demonstrate outstanding performance in terms of construction efficiency and sustainability.These advantages align well with national policies promoting the industrialization of the construction sector,leading to the rapid development of modular steel buildings in modern architecture.Extensive research has been conducted worldwide on this structural form.However,in China,studies on modular steel buildings are still at a preliminary stage,and several critical issues remain to be resolved.The collaborative load transfer mechanism between key structural components has yet to be clearly elucidated,and research on the overall structural behavior and progressive collapse resistance remains insufficient.This paper systematically reviews the recent research advances in modular steel building systems,and elaborates the discussion according to the logic of progressing from the component level to the system level.Focusing on column components(single columns and built-up columns),laminated beams and the overall structural performance,individual core components such as square steel tubular columns and complex angular section columns are first examined to analyze their independent mechanical performance.On this basis,the discussion is further extended to built-up components,including built-up columns and laminated beams,to explore the collaborative working mechanism and mechanical response characteristics between components.Finally,the overall structural performance level is then further addressed.In the end,based on the comprehensive review of existing research outcomes,potential directions for future studies are proposed to address the identified knowledge gaps and to support the continuous development and practical application of modular steel structures.关键词
