摘　　要：为研究不同受力状态下的钢筋混凝土构件等效弹性模量的取值问题,基于刚度等效原理,计算了轴心受压构件、受弯构件和4种不同偏心距下偏心受压构件的等效弹性模量。结果表明:尽管构件的受力状态不同,等效弹性模量也有差异,但等效弹性模量与构件的配筋率都呈现较明显的线性关系。For the study of the equivalent elastic modulus of reinforced concrete members under different stress states, based on the e- quivalent stiffness principle, the equivalent elastic modulus of the Axial compression member, the bending member and four kinds of ec- centric compression members with different eccentricity were calculated.The results show that the equivalent elastic modulus of the mem- bers are different owing to different stress states, but there is a linear relationship between the equivalent elastic modulus and the reinforce- ment ratio no matter what member.
