开孔式双钢管屈曲约束支撑承载力和滞回耗能的有限元分析
|
摘要
采用ANSYS建立了12个在支撑内核钢管轴向上开设单排长条孔的开孔式双钢管屈曲约束支撑有限元模型,通过低周往复轴向位移加载分析方法,研究了支撑的压(拉)承载力和滞回耗能性能受横截面上不同总开孔角度和开孔个数的影响,得到了开孔参数对压(拉)承载力和耗能指标的影响规律.
This paper establishes 12 models of double-tube buckling-restrained braces with their inner steel tubes perforated in single row in their axial direction using ANSYS.And then it discusses the impact of the different total angles and number of holes in the cross-section of the inner steel tubes on both compressive(tensile) bearing capacity and hysteretic energy behavior using the analytical method of low cyclic repeated axial displacement loading.This paper draws out the rules of the impact of perforated parameters on energy consumption indexes,and it gives some references to the practical engineering design.
