已有的研究成果已经表明,对于工型钢梁柱,绕二正交轴的弯矩承载能力是非线性的相关关系,事实上这个相关曲线很接近一个四分之一的圆。为了能更好地表达在定值轴力作用下梁柱所能承受的两个方向弯矩的相关关系,已建立有工型截面的长,短梁柱的非线性方程,这些方程经过修正后已被推荐供实际应用,因而1983年美国钢结构学会的荷载抗力因
The existing research results have shown that the bending moment load capacity of the steel beam around the two orthogonal axes is a nonlinear correlation, in fact, the correlation curve is close to a quarter of a circle. In order to better express the correlation between the two directions of moment which can be supported by the beam and column under the fixed axial force, the nonlinear equations of long and short beam columns with working section have been established. These equations have been modified Has been recommended for practical application, thus the 1983 American Institute of Steel Structure load resistance factor
