APPLICATION OF DAMAGE CONSTITUTIVE MODEL FOR CONCRETE TO THE MACROSCOPIC SHEAR WALL MODEL
In the nonlinear analysis for reinforced concrete shear wall structures, the one-dimensional equivalent empirical constitutive model and the modified compression-field theory are generally applied to calibrate the nonlinear spring stiffness of resisting shear force within the macroscopic model. In contrast, in this paper based on the two-dimensional damage theoretical constitutive model for concrete, the calibration for the nonlinear spring stiffness of anti-shear-force within the macroscopic model is discussed. Combining the axial spring stiffness calibrated by the damage constitutive model for concrete and the stress-strain relationship for steel and the shear spring stiffness constitutes the macroscopic models element stiffness matrix. Some examples for numerical verification are provided. The study indicates that this train of thoughts is feasible and correct, and provides some references for further performing multi-dimensional structural analysis.
