摘要:
选择合理的建模方法,建立衬塑钢管海水海砂混凝土短柱轴压有限元分析模型,对构件的破坏形态、轴压荷载-变形关系、内力分配进行研究,并以承载力折减系数的形式提出构件的极限承载力简化计算公式.结果表明:衬塑钢管海水海砂混凝土短柱的外钢管与内衬塑料层可较好共同工作,构件的轴压荷载-变形曲线可分为3种类型,由约束效应系数决定;随着塑料层厚径比的增大,轴压荷载-变形曲线形状相似,但极限承载力近似呈线性降低.
Abstract:
A reasonable modeling method is used to establish the finite element analysis model of seawater sea sand concrete-filled plastic-lined steel tube stub columns. The failure form, axial compressive load-deformation relationship and internal force distribution of the member are investigated, and the simplified calculation formula of the ultimate bearing capacity for the member is proposed by a reduction coefficient of bearing capacity. The results show that the outer steel tube and the inner plastic lining of seawater sea sand concrete-filled plastic-lined steel tube stub columns can work well together, and the axial compressive load-deformation curves of the member can be categorized into three types, determined by the confinement factor. With the increase of the plastic lining thickness to diameter ratio, the shapes of the axial compressive load-deformation curves are similar, but the ultimate bearing capacity decreases approximately linearly.
