Effect of Vibration from Highway Vehicle Load on adjacent Buildings and Its Assessment

Abstract

This paper studies the influence of highway vehicle loads on the vibration of nearby buildings, and both the vehicle induced vibration of ground and adjacent residential are analyzed. Firstly, testing points are arranged on both sides of a highway named Xiongchu Avenue to measure the ground vibration caused by vehicle loads. Secondly, the corresponding vibration response of a nearby residential building is measured. The natural frequency of this building is identified by NexT/ERA method. The results show that the influence of the traffic load on the frequency of the building is mainly between 8Hz to 20Hz. The acceleration level of each storey and influence of vibration on human comfort are calculated, and it is concluded that all the degree of vertical vibration are belong to the requirements in the Chinese code. This paper provides corresponding technical support for solving the problem of such traffic system.
