| 摘 要： | 现行《钢结构设计规范》(GB 50017-2003)沿用历次钢结构设计规范的规定:轧制普通工字钢简支梁的整体稳定系数φb不能引用等截面焊接工字型和H型钢的整体稳定系数φb的公式计算,而直接给出表格查用。通过分析表明,按《钢结构设计规范》(GB 50017-2003)附录B公式(B.1-1)所计算的φb,与规范GB 50017-2003中表B.2所给出的数据基本一致,因此建议今后规范统一采用公式(B.1-1)的理论公式计算φb。

| Abstract: | The current "Code for Steel Structure Design "(GB 50017-2003)still adopts the stiputations of all the previous codes,i.e.the formulas of overall stability reduction coefficient φ_b for the uniform cross-section welded I-shaped and H-shaped steel can not be used by hot-rolled I-shaped steel simply supported beam in the calculation,but the table is directly given.The analysis indicates that the φ_b calculated by formula(B.1-1) in appendix B of code GB 50017-2003 is consistent with the datas in table B.2 of same code,and it is suggested the same theoretical formula(B.1-1) should be used to calculate φ_b. |
