| 摘 要： | 钢压弯构件的空间失稳包括单轴受弯压杆的弯扭屈曲和双轴受弯压杆的失稳。目前各国钢结构设计规范对空间失稳计算的规定出入比较大。为了促进不同规范相互接近并探索统一的可能性,本文从典型截面选择、简单线性相关方程、单轴对称压弯构件和双轴受弯压杆四个方面进行了分析并指出采用简单线性相关方程来消除规范差别的可能前景。

| Abstract: | Spatial instability of steel beam-columns consists of the lateral-torsional buckling ofuniaxially bent beam-columns and the instability of biaxially bent beam-columns wheretwisting generally accompanies deflection. The provisions for checking these kinds of instabil-ity differ quite a lot in Various specifications of steel structures design. In order to atteriuatecode differences and seek the possibility of unification, the following aspects of instabilityproblem havd been investigated: (1)choice of typical cross-section, (2)simple linearinteraction equation, (3)beam-columns of monosymmetric sections and,(4)beam-columnsunder biaxial bending. It is concluded that simple linear interaction equation seems to be aprospective solution to attenuate code differences for both cases or the spatial instability ofthe beam-columns. |
