摘要:
:采用平衡法或能量法对设有二至四道弹性支撑杆的轴压钢柱的稳定性能进行分析, 得出不同屈曲波
形的柱弹性临界荷载的简化计算公式.和弹性临界荷载相对应的计算长度系数可以用于轴压和压弯钢柱的
设计计算.综合以上结果, 进一步导出有多道弹性支撑杆的柱弹性临界荷载的统一近似公式, 既可用于二至
四道弹性支撑杆的工况, 也适用于道数更多的工况.此外, 还讨论了支撑杆应满足的要求, 包括刚度、承载力
和隅撑设置, 并强调考虑杆件几何缺陷的必要性
Abstract:
The stability o f axia lly compressed steel co lumns w ith tw o to four braces a re investig ated using equilibrium a ppro
ach o r e nerg y approach .Simplified fo rmulas o f the elastic critical lo ad of the se columns are obtained fo r different buckling
co nfigura tions.The coefficient of effectiv e leng th deriv ed f rom this ela stic c ritical lo ad can be used in design calculation
of steel co lumns and beam-columns .By investig ating the abov e re sults, unified approx ima te formulas are pro po sed
for elastic critical lo ad of columns pro vided w ith multiple braces .These fo rmulas no t only apply to the case of tw o to fo ur
brace s, but also to that o f mo re than fo ur br aces.Moreover, requirements to be fulfilled by braces are discussed, including
stiffness , strength and installation of knee braces , emphasizing the necessity of considering the geometrical imperfection.
