| 中文摘要 | 钢结构轴心受压构件在板件宽厚比超过一定范围时会发生整体局部相关失稳。介绍美国、欧洲、中国和英国4种钢结构设计规范中关于轴心受压构件相关稳定的设计方法,并以焊接工字型截面轴心受压构件为例对各种规范的设计方法进行对比分析。美国钢结构设计规范通过引入屈曲折减系数Q对强度进行折减的方法考虑板件局部屈曲的影响,欧洲和英国钢结构设计规范均采用有效截面面积考虑板件的局部屈曲,并对构件长细比进行一定程度的折减。我国钢结构设计规范对于轴心受压构件相关稳定的设计方法仍需进一步研究和完善。; The overall buckling of steel axial compression members will interact with the local buckling of steel plates when the plate slenderness is high.It introduced different design methods of several design codes on the interaction of local and overall buckling of steel axial compression members,including the Chinese code GB 50017-2003,the American code ANSI/AISC 360-10,the European code Eurocode 3,and the British code BS 5950-1∶ 2000.And the comparison was made among these codes by taking welded I-section axial compression member as an example.ANSI/AISC 360-10uses the Q-method,while others use the effective area method.This paper also indicated that GB 50017-2003needed more improvement for the design methods on interaction buckling. |
