高层工业厂房人行荷载下振动舒适度研究

A Research on the Vibration Comfort of High-Rise Industrial Plants Under Pedestrian Loading

工业厂房由于人员行走、设备振动等原因,通常采用低层形式。但对于高速建设的中国城市而言,提高产业用地的立体空间利用率已经成为了共识,越来越多的高层工业厂房拔地而起,“摩天工厂”应运而生。而对于高层工业厂房,振动舒适度的研究就显得更为重要。以实际正在施工的高层工业厂房为背景,采用理论分析、现场实测及有限元模拟三种方法,分析高层工业厂房在人行荷载下的楼板振动峰值加速度,通过理论分析、现场实测结果与有限元模拟结果对照,验证有限元模型的准确性;根据现场实测结果并结合有限元模拟结果,分析振动响应在同层楼板及不同层楼板之间的传递规律。

Due to the reasons such as personnel walking and equipment vibration,industrial plants usually adopt the low-rise form.However,for the high-speed construction of Chinese cities,it has become a consensus to improve the threedimensional space usage and the efficiency of industrial land.More and more high-rise industrial plants are built,and"skyscraper factories"have emerged as they are needed.For high-rise industrial plants,the study of vibration is even more important.Based on the actual high-rise industrial plant under construction,this paper adopts three methods of theoretical analysis,field measurement and finite element simulation for evaluating the peak acceleration of floor vibration of high-rise industrial plant under pedestrian loading.The simulation results are compared to verify the accuracy of the finite element model.According to the field measurement results combined with the finite element simulation results,the transmission law of vibration response between the same floor and different floors is analyzed.
