摘要:

为了有效评估地铁运行引起的上盖建筑振动污染对结构舒适度的影响,分析了车致振动下上盖建筑的振动响应规律。采用分离式建模的方法构建了上盖结构的二级竖向振动响应动力模型,用集中质量法对上盖结构的响应规律做了整体分析,基于欧拉-伯努利梁建立了楼层内振动响应模型。基于所建立的二级振动理论模型,利用MATLAB_Appdesigner工具箱开发了结构振(震)动信号分析系统。结果表明:随着楼层的增加,振动响应呈现上升趋势,增幅随着楼层的增大趋于稳定; 随着结构的自振周期延长,动力响应会从高频段向中低频段发生偏移; 板内的振动响应并非单纯发生在基频附近,而应该根据荷载的动力特性与结构自身特性综合考虑; 位移响应体现了荷载全频段的作用效果,加速度响应更加体现荷载卓越频段的作用效果。

Abstract:

In order to effectively evaluate the influence of vibration pollution of superstructure caused by subway operation on the comfort of structure, the vibration response law of the superstructure under vehicle-induced vibration was analyzed. A two-level vertical vibration response dynamic model of the superstructure was constructed by a separated modeling method. The response law of the superstructure was analyzed as a whole by the concentrated mass method. A floor vibration response theory was established based on the Euler-Bernoulli beam. Based on the established two-level vibration theory model, a structural vibration(seismic)signal analysis system was developed using the MATLAB Appdesigner toolbox. The results show that as the number of floors increases, the vibration response shows an upward trend, and the amplitude tends to stabilize as the number of floors increases. As the natural vibration period of the structure prolongs, the dynamic response will shift from the high frequency range to the mid low frequency range. The vibration response inside the plate does not simply occur near the fundamental frequency, but should be comprehensively considered based on the dynamic characteristics of the load and the characteristics of the structure itself. The displacement response reflects the effect of the load in the full frequency range, while the acceleration response further reflects the effect of the load in the excellent frequency range.
