Study on Elastic-Plastic Response Prediction of Parallel Beams

Abstract

Since earthquakes that are heavier than the assumed one have broken out in recent years, the conventional earthquake-resistant plans of plant piping are inadequacy and rational plans by flexible views are searched for recently. This paper describes about elastic-plastic response of a beam of SUS304. The experimental object used in this study has parallel two beams that have narrow parts. The seismic excitation tests by natural frequency were performed with several input levels. Damping ratio and natural frequency were shown by the function of response displacement and the simulation program was made. This simulation showed the tendency of experiments well. Improvement in the precision is a future subject.
