摘要:
为探讨设置低屈服点加劲耗能壁板对箱形钢墩柱受力性能的影响机理,采用有限元法对3类设置加劲耗能壁板的新型箱形钢墩柱轴压性能进行数值分析,并探讨设置加劲耗能壁板对箱形钢墩柱的荷载-位移曲线、位移延性系数及承载能力的影响规律.结果表明:耗能壁板高度及宽度对箱形钢墩柱的承载能力和延性影响较大;构件承载能力随耗能壁板高度增大而增大,但随耗能壁板宽度增大而减小;构件延性随耗能壁板高度及宽度增大而增大;加劲肋的厚度、宽度及设置数量均对箱形钢墩柱的承载能力和延性有一定影响.
Abstract:
In order to investigate the effect of the low yield point stiffening energy dissipation plates on the mechanical behavior of steel box piers under axial compression, three types of the new steel box piers with different stiffening energy dissipation plates were analyzed using the finite element method. The influences of stiffening energy dissipation plates on load-displacement curves, displacement ductility coefficient and bearing capacity of the steel box piers were discussed. The results show that the height and width of the energy dissipation plates greatly influence the load capacity and the ductility of those steel box piers. The load capacity of the steel box piers is positive correlated to the height of energy dissipation plates, but is negative correlated to the width of the plates. The ductility of the steel box piers is positive correlated to both the height and width of the energy dissipation plates. The effects of the thickness, width and the setting numbers of the energy dissipation plates on the loading capacity and ductility of the steel box piers are obvious.
