摘要

In recent years, the importance of the fracturing test using the full-scale model is recognized in order to upgrade an earthquake resistant design. It is, moreover, important to develop a new measurement method which can measure a complex three-dimensional behavior in such fracturingtest. This study has been doing research and development of three-dimensional measurement method using an image processing technique for a measurement of dynamic displacement in shaking table test without any contact. This measurement system is a very convenient system because it can measure the three-dimensional dynamic displacement in the simple experimental condition that the several makers are only attached to the surface of an experimental structure. The system therefore is the most suitable measurement system for an evaluation of complex three-dimensional behavior of test model. This paper describes the measurement results of shaking table test using actual scale wooden house model in E-Defense that is the largest shaking table facilities, and evaluates synthetic measurement performance of the developed new measurement system.
