摘要:

基于地铁车站的有限元模型,通过非线性时程分析得出不同抗震设计方案下中柱柱顶的轴压比演变规律,并进行数值量化; 基于量化后的变轴压比演化方式,采用经试验验证的中柱模型,探究了变轴压比的变化频率、变化幅值和变化相位对中柱滞回性能的影响,并讨论了中柱的混凝土损伤。结果表明:中柱柱顶的水平位移和竖向轴压比变化具有明显的异步性,后者变化频率更快,后者的变化频率约为前者的1.4倍～3.8倍,竖向轴压比的变化幅值为0.08～0.68; 相较于施加竖向恒定轴压比,在中柱柱顶施加的高变轴压比对柱的承载力、能量耗散和刚度退化产生了显著的不利影响,并加剧了柱的混凝土受压损伤; 竖向变轴压比的变化频率为3和幅值变化大的工况损伤尤为明显,承载力和能量耗散分别降低约50%和74%。

Abstract:

Based on the finite element model of subway station, the evolution law of axial compression ratio of central column top under different seismic design schemes was obtained through nonlinear time history analysis, and the numerical quantification was carried out. Based on the quantified evolution mode of variable axial compression ratio, the influence of variable frequency, amplitude, and phase of variable axial compression ratio on hysteretic properties of central column was explored through the experimental verified central column model, and the concrete damage of central column was discussed. The results show that the horizontal displacement of the central column top and the vertical axial compression ratio change asynchronously, the latter change frequency is faster, the latter change frequency is about 1.4-3.8 times of the former, and the vertical axial compression ratio change amplitude is 0.08-0.68. Compared with the vertical constant axial compression ratio, the high variable axial compression ratio applied on the central column top has a significant adverse effect on the bearing capacity, energy dissipation, and stiffness degradation of column, and aggravates the concrete compression damage of column. When the frequency of vertical axial compression ratio is 3 and the amplitude is large, the damage is particularly obvious, and the bearing capacity and energy dissipation are reduced by about 50% and 74% respectively.
