十字形钢异形截面压弯构件的滞回性能研究
RESEARCH ON THE HYSTERETIC BEHAVIOUR OF CROSS-SECTION SPECIAL-SHAPED STEEL COLUMNS
【摘要】 利用大型通用有限元分析软件ANSYS分析了十字形钢异形截面压弯构件受常轴力、循环弯矩作用下的滞回性能、强度、变形、延性及破坏特征,得到其滞回性能的主要影响因素及影响规律,可为抗震设防区采用十字形钢异形柱设计提供依据。
【Abstract】 Using the finite element analysis software ANSYS,it was researched that the hysteretic behaviour,strength,deformation,ductility and damage features of the cross-section special-shaped steel columns forced by regular axial compression and cycle moment.And found the main factors effecting the hysteretic behaviour and the influence laws.Which provided a basis for the design and use of the cross-section special-shaped steel columns in strong earthquake defensive zones.
