摘要
本文阐述了损伤理论的发展情况,分析了Loland损伤模型和Marzars损伤模型的优缺点。提出了将Loland模型和Marzars模型修整后的损伤模型运用到纤维混凝土中,并导出应力应变全曲线方程。
The development of damage theory of concrete is expounded, and Loland＇ s damage model and Marzars＇ s damage model is analyzed. The modified model through Loland ＇ s model and Marzars ＇ s model is applied to the steel fiber reinforced concrete. The cured equation of relationship between stress and strain can be deduced from modified model.
