鋼構造柱脚部の終局耐力に関する実験的研究 (その1)

Abstract

Two series of experiments were carried out to investigate the ultimate load carrying capacityand failure mechanism of steel column bases. First, five simple specimens composed of varioustypes of steel column bases and a concrete base block were tested under pure compression toexamine the behavior and the failure mechanism of base plate and stress distribution in concreteunder base plate. Secondly, three column base specimens composed of a column of H-shapebase plate with 16 mm thickness and reinforced concrete base block were tested to investigatethe elastic-plastic behavior and the ultimate load carrying capacity and to establish the designmethod based on the ultimate strength, and certified that the additive method for a design pro-posed by the first author would be available with a sufficient accuracy.
