The Effects of Micro-Vibration Excited by Traffic Vehicles on Xi'an Bell Tower
Publication: International Conference on Transportation Engineering 2009
Abstract
In order to inspect to the influence of micro-vibration excited by vehicles on timber structure of Xi'an Bell Tower, dynamic response test had been carried out. The vibration model of timber structure has been established and the security evaluation of timber structure has been accomplished based on GB/T50452-2008. The results indicated that the differences of vibration levels in timber structure are extraordinary obvious during the different interval time. Comparing the vibration levels of the column foundation, the vibration levels of upper floor are enlarged obviously. The differences of vibration levels in timber structure in the horizontal vibration velocity (in the NS and EW directions) are also obvious. It is shown that the vibration velocity at top of timber structure column exceeded limited value of GB/T50452-2008 during the interval times with high volumes and speeds of traffic vehicles.
