| چکیده | ||
| In this paper, a new approach for nonlinear numerical modelling of the reinforced concrete shear walls with consideration of bar-concrete interaction and shear deformation is proposed. Bar and concrete stress-strain relations, the bar-concrete interaction, the shear stress-strain relation and, also, their cyclic behavior including the strength degradation and stiffness degradation are adopted as known specifications. In the modeling, shear wall is divided into two types of joint and reinforced concrete (RC) elements. In the RC element, the effect of shear deformation is considered based on Timoshenko beam theory. Separate degrees of freedom are used for the steel bars and concrete part. The effect of bar-concrete interaction has been considered in the formulation of the RC element. The reliability of the method has been assessed through the comparison of numerical and experimental results for a variety of tested specimens under cyclic and pushover loading. A good agreement between experimental and analytical results is obtained for both cases of strength and stiffness during the analysis. | ||
