摘要
以一既有混凝土简支梁为研究对象,基于损伤力学理论方法,研究老化混凝土的力学性能,建立了老化混凝土本构模型.利用此本构模型,对既有混凝土简支试验梁进行了数值模拟,验证了基于损伤力学理论建立的混凝土本构模型的正确性.
Using a method from Damage Mechanics and putting its engineering background on some existing simply-supported concrete beam, this paper researches the mechanical performance of the aging concrete and then achieves some aging concrete constitutive equations. By means of these equations, the paper analyzes the performance of this existing simply-supported beam with the method of numerical simulation. Results show that the constitutive equations based on Damage Mechanics are correct and justified.
