一、前言已知,在细长的柱中,在破坏瞬间,柱将产生很大的侧移f_p使这时实际偏心距增大而导致承载能力显著降低,因此在计算时必须考虑长柱的纵向弯曲影响,图1示柱的承载能力(用承载能力系数n=N_p/R_abh_o表示)和偏心率(e_o/h_o)的关系曲线。图1是根据偏心受压构件研究小组提出的综合报告中建 I. Introduction It is known that in the slender column, at the moment of destruction, the column will produce a large lateral displacement f_p so that the actual eccentricity increases and the bearing capacity is significantly reduced. Therefore, the long column must be considered in the calculation. Longitudinal bending effects, Figure 1 shows the load capacity of the column (represented by the load capacity coefficient n=N_p/R_abh_o) and eccentricity (e_o/h_o). Figure 1 is a comprehensive report proposed by the research group of eccentric compression members.
