摘　　要：讨论了混凝土实测总应变与温度之间、应力应变与应力之间的相互关系,强调了在温度变化的情形下实测总应变因结构型式及约束条件的不同可能呈现出不同的变化形态,认为混凝土应变和应力的关系与线性弹性材料特性有可能截然不同,不能进行简单类比。The relationship between the total strain and the temperature of concrete and that between the stress-strain and the stress of concrete are discussed.It is stressed that the variation of the total strain with the temperature depends on the structural types and the constraint conditions.It is clarified that the relationship between the strain and the stress of concrete is different from that of linear elastic materials.They cannot be simply compared with each other.

关 键 词：混凝土 总应变 应力应变 应力 变弹模
