1332 Measurement of three dimensional displacement using image processing system : Application to a collapse experiment of a detached wooden house

Abstract

The shaking table tests using real scale structure have been carried out in recent years. It is difficult that the dynamic response displacement of such test model by using existing displacement transducer, specially, it is severe problem to measure the fracturing or collapse process of real scale model using contact type displacement transducer with good accuracy. This study has developed the measurement method of three dimensional displacement using image processing system. This paper describes the measurement result of collapse process of real scale wooden house model in E-Defense.
