摘要:
基于有限元程序ABAQUS,建立双金属复合管海水海砂混凝土(SSCFBT)短柱构件的精细化有限元模型,对轴压状态下模型的破坏形态、荷载-变形关系、内力分配和钢-混凝土界面接触作用进行研究,并开展参数分析。结果表明:双金属复合管与内填混凝土之间的共同工作性能良好,其荷载-变形曲线可分为3种类型,由双金属复合管对混凝土的约束效应系数决定。通过参数分析,得到了不同参数对SSCFBT短柱轴压承载力的影响规律,并验证了已有相关计算公式用于预测SSCFBT短柱轴压承载力的可行性。
Abstract:
Based on the finite element program ABAQUS, a refined finite element model is established on seawater and sea sand concrete-filled bimetallic tube(SSCFBT)short columns. The failure mode, load-deformation relationship, internal force distribution, and steel-concrete interface contact of the model under axial compression are studied and parametric analysis is conducted. The results show that the co-working performance between the bimetallic tube and the concrete infill is favorable. The load-deformation relationship curves can be divided into three types, which are determined by the confinement factor of the bimetallic tube on the concrete. Through parameter analysis, the influence of different parameters on the axial compressive bearing capacity of SSCFBT short columns is obtained, and the feasibility of related calculation formulas for predicting the axial compressive bearing capacity of SSCFBT short columns is verified.
