【摘要】 钢结构因具有强度高、质量轻等优点,在工程中得到广泛应用。压弯构件是钢结构中应用较为广泛的一种构件形式,其稳定性和承载力对整个工程的安全性具有重要的影响。GB 50017-2003《钢结构设计规范》对于钢结构压弯构件稳定性的规定,主要针对的是普通钢钢结构构件,且有些条款存在设计不合理的情况,有待完善。高强度钢材构件有众多优点,但在承载力计算等方面,现行GB 50017-2003对高强度钢材的工程应用表现出较大的限制性。为此,对国内学者所进行的普通钢压弯构件稳定性的理论研究,以及国内外学者对高强度钢材压弯构件的研究进展进行总结,并对高强度钢材压弯构件的研究与应用提出展望。更多还原

【Abstract】 With the advantages of high strength and light mass,steel structural members have been widely applied in many engineering projects.Beam-column is a widely used structural member,and its stability and bearing capacity have important influences on the safety of the whole structure.The design provisions for the stability of bending members in Code for Design of Steel Structures(GB 50017-2003)are mainly for ordinary steel structural members,and some unreasonable design provisions are needed to be modified.High strength steel has many advantages,but its engineering application has been restricted by the existing design codes.Therefore theoretical research on ordinary steel bending members in China and research progress of high strength steel bending members at home and abroad were summarized,and prospect of study and application of high strength steel bending members was proposed.更多还原
