摘要
通过对L型畀形柱和135度截面异形柱进行数值模拟研究,分析在低周往复荷载作用下两种类型异彤柱在轴压比、加载角度等因素下的抗震性能。结果表明:高轴压下异形柱的承栽力有所提高但延性降低,L型异彤柱的承载能力和耗能能力均优于135度异形柱,斜向加栽构件耗能较大、延性差,在抗震设计中应引起足够重视。
;Through numerical simulation of L special-shaped columns and 135-degree cross section column,two types of special-shaped columns are analyzed under low cyclic loading axis pressure ratio,loading angle seismic performance factors.The results show thai high axial pressure bearing capacity of special-shaped columns has increased with ductility reduced.The carrying capacity and energy dissipation capacity of the L-shaped columns are better than 135 degrees shaped columns.The oblique loading columns appear large energy consumption and poor ductility.Attention should be paid to it in the seismic design.
