摘要:
方钢管混凝土柱的抗震性能与钢管的局部屈曲有关,柱端设置约束拉杆可以提高钢管的局部稳定,从而增强方形钢管混凝土柱抗震性能.采用三维有限元法,分析方钢管混凝土柱在竖向及水平荷载联合作用下的抗侧力-位移关系,有限元分析的结果得到试验结果验证.利用有限元模型分析轴压比、钢板宽厚比,以及内填混凝土抗压强度对方钢管混凝土柱抗震性能的影响.完成柱端设置约束拉杆的方形钢管混凝土柱在竖向及水平荷载联合作用下三维有限元分析,与试验结果相比较并作分析.
Abstract:
The aseismic behavior of square steel tube concrete filled column is related to the local stability of steel tube,the stability can be improved by installing confining rods at the end of column,thus the aseismic behavior of the column can also be strengthened.Using 3D nonlinear finite element method(FEM),the authors analyze the relationship between the horizontal force and its displacement of the column under vertical force.The FEM results are in agreement with experiment ones,indicating the validity of FEM analysis.The influences of axial compressive ratio,width-thickness ratio of steel plate of tube,and the strength of filled concrete on the aseismic behavior of the column are discussed.Furthermore,the analysis of 3D nonlinear FEM on the square steel tube concrete-filled column with confining rods under both vertical and horizontal forces,are carried out,its FEM results are also compared with the experiment ones.
