アーチの極限解析

Abstract

This paper treats some discussions on the collapse modes and the finalbearing capacities of arches and also shows a practical method of the limit analy-sis of arches. It is shown that the collapse mode of an arch takes several typefrom one to another with the varing rise, and also explained that the mode and thefinal capacity of a flat arch transfer continuously to those of a straight beam whenthe rise of the arch is flatte~ned to zero. The effects of the excentricity of loading.The ratio of section depth to span and the end conditions are discussed.
