摘要
近年来,已出现了许多种混凝土的本构方程,哪一种最好尚无一致的答案。由于内时理论能真实地模拟混凝土的多轴本构行为的基本特征,本文对此进行了简要回顾,并将它应用于钢筋混凝土梁的分析中,且就分析结果与试验值进行了比较,理论计算能得出令人满意的精度。
In recent years, a lot of constitutive laws of concret have been published. Which is the best? There has not been a unanimous answer yet. Endochronic theory, being able to model realistically the basic features of triaxial response of concrete, is reviewed and applied to the analysis of reinforced concrete beams in the paper. Analytical results have been compared with test ones, and the calculated values possess satisfactory precision.
