摘要:
作者以混凝土试件外套一钢筒作为刚性元件的方法,测得了强度为200~750kg/cm~2混凝土的应力—应变全曲线。分析了决定混凝土应力—应变全曲线形状的特征值及其与混凝土极限强度的相关关系。根据混凝土应力—应变全曲线的特征和混凝土的破坏过程,将应力—应变全曲线划分为混凝土应力上升段、混凝土裂缝扩展及贯穿段和混凝土破碎段,并提出了相应的表达式。
Abstract:
The complete stress-strain curves of normal concretes of strength from 200 kg/cm~2 to 750 kg/cm~2 are obtained by using a steel tube as a rigid element. The characteristic values of concrete on the key points of curve are discussed, which determine the curve shape. It is found that there are good correlativities between the characteristic values and the ultimate strength of concrete. On the basis of the curve characteristics and the failure behavior of concrete, the curve can be reasonably divided into three portions: stress ascending, crack developing and interconnecting, and concrete disintegrating. The expressions corresponding to each curve portion are presented.
