关于钢结构抗震设计中轴心受压支撑长细比问题的讨论
|
摘要
在简要阐述钢结构稳定理论的基础上,结合有关规范和试验资料,讨论钢结构抗震设计时轴心受压支撑构件的长细比限值及抗震承载力验算时不同钢种的长细比修正问题,指出在弹性屈曲范围的长细比不应进行钢号修正。
Following a brief review on the stability theory of steel structures,the modification of slenderness ratio limits and the slenderness ratio in calculating the aseismic capacity of axial compression bracing members for different steel grades are discussed based on relevant codes and experimental results.The analytic results show that the modification of the slenderness ratio for bracing members is not appropriate in the elastic buckling range.
