铁路桥梁新型柱板式高墩双柱模型的抗震性能
|
摘要
采用往复荷载下的钢筋和混凝土本构,用非线性有限元分析法研究铁路桥梁新型柱板式高墩双柱模型在低周往复荷载作用下的滞回特性、延性及耗能等抗震性能,研究墩柱截面形式、腹板厚度、墩柱配筋率对这些特性的影响。通过对4个缩尺模型的拟静力试验,进一步研究轴压比、腹板厚度和水平加载制度等对柱板式高墩破坏性状的影响。研究结果与数值模拟结果吻合较好,说明本文采用的分析方法结果可靠,新型柱板式高墩具有较好的抗震性能。
Hysteresis constitutive laws of concrete and steel reinforcement were adopted to study the hysteretic characteristics,ductility behavior,energy dissipation capacity and seismic performance of the late-model column-slab high piers in double-column model under cyclic loads.And the influences of column cross-section forms,wall slab thickness and reinforcement ratio of columns were also taken into account.Based on the pseudo-static test conducted on 4 reduced scale model,the effect of axial compression ratio,web thickness and horizontal loading system on the failure behavior of the column-slab high piers was further studied.The test results are agreed well with the numerical simulation results,which shows that the analysis method used in this work is reliable.The late-model Column-slab high pier has a better seismic performance.
