Abstract |
Earthquakes are reported that building structures have been colossal damaged, but before 1998 designed structures which were not applicate seismic design code have no seismic performance. Especially, for the apartment structures were indicated that it have no resist wall element of earthquake before 1988 designed structures. We have to evaluate for seismic performance evaluation for model structures by MIDAS which is general structure analysis software. In this study, it was performed shaking table test to evaluate model structure which is reinforcement concrete and 5 floors for seismic performance index. We made specimens by similar's law and tested shaking table test. In the shaking table test, it is mot performed prototype model test because of space and equipment condition. So we had made scale-down model for 1/5 by similar's law. That's why it needs for the evaluation of performance. However, it is not possible to do an experiment of prototype owing to the shortage of space and the limit of an experimental instrument in the shaking table test. Then, modeling and reducing the part of prototype do the experiment. In this experiment, a shaking table test is done and seismic performance of model structures is evaluated by using similitude laws for scale down specimen. As a result, it is proved that non-seismic design structures meed to retrofit since seismic performance shows life safe grade in 0.12g of an earthquake.
