摘要
对GB 50017—2003《钢结构设计规范》与GB 50017—2017《钢结构设计标准》中与角钢相关的条文进行了对比分析,主要涉及角钢的连接形式、计算长度、容许长细比的确定与复核、设计强度的取值、轴心受压稳定性复核等。通过对比分析,列举了两本钢规(标)在角钢相关规定中的差异,并给出了对相关条文的理解与在应用时的建议。
Taking the test questions of angle steel involved in the national first-class registered structural engineer professional examination over the years as an example,this paper makes analysis and comparison of the relevant main provisions about angle steel in the national standard GB50017—2003 Code for Design of Steel Structures and the new edition of GB50017—2017 Standard for Design of Steel Structures,and the major contents focus on the application of relevant provisions about the connection form of the angle steel,calculated length,review and determination of slenderness ratio,value of design strength,review of axial compression stability,et al,which was illustrated as drawings.Through comparative analysis,the differences of the two versions code or standard in the relevant provisions of angle steel are summarized,and understanding of the relevant provisions and suggestions for application are also proposed.
