高强度钢材钢结构研究进展综述

OVERVIEW OF RESEARCH PROGRESS FOR HIGH STRENGTH STEEL STRUCTURES

高强度钢材钢结构在结构受力性能、建筑使用功能以及社会经济效益等方面具有显著优势,近几年开始在国内外多个建筑和桥梁结构中取得了成功应用。该文全面综述了国内外学者针对高强度钢材钢结构在材料和构件层面受力性能方面取得的研究成果,包括材料的静力拉伸力学性能和韧性、断裂以及疲劳性能,构件的受压稳定和抗震性能,以及连接节点的力学性能等内容,为此类新型钢结构进一步的研究工作及设计方法制定提供参考,同时促进其在我国钢结构工程的应用。

High strength steel has been applied in many modern building and bridge steel structure constructions in recent years, due to their advantages in structural, architectural and economic benefits. Recent researches on mechanical performance of high strength steel structures in the level of both materials and members were comprehensively reviewed, including the static tension mechanical property, toughness, fracture and fatigue performance of high strength structural steel, the compression buckling and seismic behavior of high strength steel members, and the mechanical property of high strength steel connections. This literature review may provide a valuable information for both further relevant investigations and a proposal for design methods, and also promote the engineering application of high strength steel structures in China.
