    摘要
  • 摘要: 比较了在美国ANSI/AISC3602005，英国595012000，加拿大CAN/CSAS162001，澳大利亚AS41001998，日本AIJ2002和我国GB500172003七本钢结构设计规范中，受弯构件稳定设计的计算公式，介绍了许多学者关于这一问题的理论分析和试验研究成果，着重介绍了用有限单元法、有限差分法等数值法给出的，在多种横向荷载作用下非均匀受弯构件等效弯矩系数b的表达式。对于线性非均匀简支受弯构件的等效弯矩系数b，在我国钢结构设计规范中，从TJ1774至GB500172003，一直沿用了由M.G.Salvadori在1956年用瑞利-里兹法得到的两端简支受弯构件的等效弯矩系数b曲线中的下限值，此值与其他几个国家的钢结构设计规范中采用的b的计算公式不同。在参考他人研究成果的基础上，提出了一个简明的，计算任意弯矩分布和任意支承条件的，受弯构件等效弯矩系数b的表达式。此式连同经修改的梁的弯扭屈曲设计公式，可供下一轮修订我国钢结构设计规范时参考。
    Abstract: It is given the comparison of specifications for the stability design formulas in American ANSI/AISC 3602005,British 595012000,Canadian CAN/CSAS162001,Australian AS 41001998,Japanese AIJ2002 and Chinese GB 500172003.The theoretical analyses and experimental researches are given.The equivalent moment factors of non-uniform bending beams,on various loading cases by finite element and finite difference methods are presented.From Chinese specifications of steel structures TJ 1774 to GB 500172003,the equivalent moment factor _b for the simply supported beam,under linear non-uniform bending,is adopted,which is its approximate minimum value and is derived by M.G.Salvadori,taken from L.Rayleigh,W.Ritz,method at 1956.The value _b is different from that in other specifications for design of steel structures.Referring the academic researches,a closed-form expression of calculating equivalent moment factor for any moment distribution and end support conditions is presented.This expression together with the revised flexural-torsional buckling design formula of beam may be provided for next cycle revision of Chinese Code for Design of Steel Structures.
