Investigation of the Accuracy for the Measurement of Micro Vibration

摘要

Traffic-induced building vibration is a major environmental problem specifically for adjacent building hospital and high-tech industries building since it may result in structural damage and malfunctioning of sensitive equipment The Juo Chiun Building and NCKU Hospital are the example of buildings as mentioned that its location adjacent to the highway and are susceptible to vibrations due to traffic load Such vibration described occurs in free field as well The experimental measurements can be performed to determine the traffic-induced vibrations in buildings and free field This study focuses on the investigation of the accuracy of the experimental instruments for the measurement of micro vibration especially the micro vibration induced by road traffic The measurement at three different experimental sites (Juo Chiun Building NCKU Hospital and Chang Rong Rd ) conducts by using of different voltages and sampling rates then the results will be illustrated analyzed visually and compared in this thesis in order to ensure the accuracy Besides the maximum dB-frequency diagram obtained from field experiment in both of the Juo Chiun and NCKU Hospital buildings will be studied The maximum dB-frequency diagram results will be compared with the table of vibration guideline to indicate the appropriateness of the building as the semi-conductor building
