摘要:

为了考察地铁上盖大底盘-层间隔震塔楼在竖向地震作用下的响应,对大底盘-层间隔震塔楼竖向振型的特点、周期和振型质量参与系数进行了分析。在设防烈度竖向地震作用下,通过振型分解反应谱法和时程分析法考察大底盘-层间隔震塔楼结构的基底剪力、隔震垫反力和转换梁内力,研究塔楼高度、隔震层竖向刚度等参数对大底盘-层间隔震塔楼竖向地震响应的影响。结果表明:大底盘-层间隔震塔楼结构存在塔楼竖向主振型,随着塔楼高度增高,竖向主振型的周期和振型质量参与系数逐渐加大; 在设防烈度竖向地震作用下,塔楼底部竖向地震力与重力荷载代表值之比(垂重比)的平均值为0.35,比非隔震塔楼平均增大4.6%; 隔震垫竖向地震反力与重力荷载代表值下反力之比(反力比)的平均值为0.30; 大底盘转换梁竖向地震下弯矩与重力荷载代表值下弯矩之比(弯矩比)的平均值为0.31; 随着塔楼高度增大,垂重比、隔震垫竖向反力比以及转换梁弯矩比均相应减小。

Abstract:

In order to investigate the response of subway large base-inter-story isolated tower under vertical earthquake, the characteristics of vertical vibration mode, period and mode mass participation coefficient of the large base-inter-story isolated tower were analyzed. Under the vertical seismic action of fortification intensity, the base shear force, vertical seismic force of the isolated supports and the internal force of transfer girders of the large base-inter-story isolated towers were investigated by mode decomposition response spectrum method and time-history analysis method. At the same time, the influence of tower height and vertical stiffness of isolation layer on vertical seismic response of the large base-inter-story isolated tower were studied. The results show that there is a vertical dominant vibration mode in the large base-inter-story isolated tower structure. With the increase of tower height, the period and the mode mass participation coefficient of vertical main vibration mode gradually increase. Under precautionary intensity vertical earthquakes, the average value of the vertical seismic force-weight ratio between vertical seismic force at the bottom of the tower and gravity load representative value is 0.35, and the average increase value is 4.6% compared to non-isolated tower. The average value of the isolated supports' vertical seismic reaction-weight ratio between the vertical seismic reaction and the reaction under the gravity load representative value is 0.30, and the average value of the transfer girders bending moment ratio between bending moment under vertical earthquake and bending moment under gravity load representative value is 0.31. With the increase of tower height, the vertical seismic force-weight ratio, the vertical seismic reaction-weight ratio of the isolated supports and the bending moment ratio of transfer girders decrease correspondingly.
