摘要
本文利用非线性有限元分析平台OpenSees建立了十种不同混凝土填充高度的钢桥墩试件纤维模型,并进行数值分析。计算结果表明在不同轴压比下,试件模型均有相对应的混凝土合理填充高度。在实际结构设计的轴压比范围内,混凝土填充0.3~0.5倍的桥墩高度是合适的。
In this paper,10 fiber models of steel piers with different concrete filled height were modeled and calculated using the nonlinear finite element analysis program OpenSees.The results show that each of the specimens with different axial-load ratios has its reasonable concrete filled height correspondingly.Within the practical design axial load ratio range,the reasonable concrete filled height is about 0.3 to 0.5 times of the pier height.
