圧縮芯をもつ鋼製橋脚の耐震性能実験

Abstract

Since the Great Hannsin Earthquake, many reaerches had been done on the steel bridge piers but few works had presented for high performance of seismic resistance. In this study, new idea inproving the ductility of steel bridge piers are proposed, in which steel piers have a central core column. Compareing with usual piers, the same number of test specimens are served for seismic repeated loading as pier models with central core columns. The test results show the excellent high seismic performance than the normal ones.
