摘要
为了研究钢板剪力墙抗火性能,本文应用有限元软件ABAQUS,建立一个三层三跨钢框架内嵌钢板剪力墙有限元模型,研究六种工况在ISO-834标准升温曲线下的梁挠度、柱侧向位移和钢板应力变化,对比结果表明:起火源越靠近梁,梁变形越大;柱侧向变形与受火位置和约束条件有关,边跨受火对结构侧向变形最不利;受火结束时应力主要集中在梁柱节点,应加强节点保护。
In order to study the fire resistance of steel plate shear walls,In this paper,a finite element model of steel plate shear wall embedded in a three-story three-span steel frame is established by using the finite element software ABAQUS.The deflection of beam,lateral displacement of column and stress change of steel plate under six working conditions under ISO-834 standard heating curve were studied.Contrast results show that:The closer the fire source is to the beam,the greater the deformation.The lateral deformation of the column is related to the fire location and constraint conditions.The side span is most unfavorable to the lateral deformation of the structure.The stress at the end of fire is mainly concentrated on the beam column joints,and the joint protection should be strengthened.
