摘要
对于焊接组合工字形截面轴心受压构件,根据等稳原则,结合局部稳定、刚度条件和施工构造要求,推导出构件轴压力与其长细比之间的关系表达式,从而快捷得到轴心受压构件的最佳长细比。最后根据局部稳定的要求得到相应的截面参数,截面设计准确、简捷。
For axial compression structural member of welded Lshape section,according to the stability bearing capacity of the structural member about two main axises be equal, local stability, rigidity condition and structural requirement of the structural member, the relation between the load on the structural member and the best slenderness ratio can be obtained. Finally,according to local stability, the parameters of section can be obtained. The design of section is exact and forthright.
