摘    要:综合考虑轴心受压构件整体稳定、局部稳定、刚度条件和构造要求,取组成柱的板件宽(高)厚比值等于局部稳定要求的最大限值,且柱绕两个主轴丧失稳定时的整体稳定承载力相等,由整体稳定条件推导得出柱承受的荷载与了佳长细比之间的关系表达式和数值表,以及柱截面细部尺寸的计算公式,按照所得公式,一次便可确定出用钢经济的截面尺寸。

关 键 词:轴心受压柱  整体稳定  局部稳定  简捷设计

Abstract:The stability,local buckling,rigidity condition,and structural requirement of the column are comprehensively considered.It is assumed that the width(height) to thickness ratio of plates of the column be equal to the required maximum limit of local buckling and the stability bearing capacity of the column about two main shafts be equal,thus,according to the stability condition,the relation between the load on the column and the best slenderness ratio can be obtained and the calculation formulas of the section detail dimensions of the column can also be obtained.According to the formulas,the economical section size of the welded I shape section column under axial compression can usually be determined directly.
Keywords:column under axial compression  stability of column  local stability  forthright design
