供試体寸法と骨材粒径の異なるコンクリートの塑性変形挙動と応力度-ひずみ度曲線の表示式

Abstract

The purpose of this study is to propose the mathematical expression of the inelastic stress-strain relationships of concrete prisms made with different maximum size of aggregate and different size of specimen up to large Commpressive strain. These are based on experimental data obtained by using a stiff compressive testing machine. Compressive strength and the inelastic stress-strain behaviors are examined in terms of the size of specimen and maximum size of aggregate. The last is that the stress-strain curves of concrete based an experiments are subsequently compared with those calculated by the mathematical expression.
