矩形断面鋼製橋脚の耐震性能に関する実験的研究

Abstract

Several types of rigid frame are utilized according to the conditions of location in the highway in a city. The rectangular section with the long side toward a bridge axis is generally used in rigid frame pier. Researches on the steel piers with oblong section have not been done, so far. Then, experimental study is conducted to investigate the seismic performance of rectangular steel section piers, with and without concrete inside the pier bottom. Making α as the aspect ration (length, width ratio) of oblong section, ten values of this parameter are used in the test. A square section pier with taper steel plate is also examined in order to investigate efficacy of the taper plate.
