• A PROPOSAL OF MEASUREMENT AND ANALYSIS METHOD FOR DETECTION OF PLASTIC RESPONSE OF STRUCTURES USING SENSOR NETWORK

抄録

 The simplest structural design such as single column dominates the majority of the viaducts for the railways and the highways. For these viaducts with simple design, i) a method for detection of plastic response of structures under seismic load based on restoring force characteristics, ii) a method for synthesis of restoring force characteristics solely based on acceleration measurement and iii) a method for detection of plastic response of structures using sensor network are proposed in this paper.<br> A pair of time synchronized acceleration data sets obtained from accelerometers installed on the top and the bottom the existing viaduct and the SDOF model for viaducts with relatively simple design plays the significant role in the synthesis of the restoring force characteristics.<br> This paper presents the overview of the measument and analysis method of restoring force characteristics based on acceleration measurement. Then, the applicability and the limitation of the proposed method are discussed based on the results from shaking table experiment.
