Abstract
This paper introduces several new damage states for shear walls with flexural behavior damaged in an earthquake. These damage states are deducted by carefully interpretation of reported available test results of shear walls in the literature. Moreover, two methods for obtaining the plastic hinge modification factors of strength, stiffness and ductility capacity of the damaged shear walls with the flexural behavior are presented. A method based on secant stiffness at maximum displacement of each cycle of observed damage and the second method uses the reloading stiffness of the hysteresis curves consistent with damage levels. The later method introduced in this research is more reasonable for obtaining modification factors among the introduced methods. Using these factors, a reliable residual capacity for damaged structures can be assessed and the proper seismic retrofitting method can be followed. In this research, the effects of damages caused by various experimental tests have been studied on 43 reinforced concrete shear walls with flexural behavior. By introducing and describing the bending performance's damage levels, given the shear wall's observable condition such as cracks' width, concrete spalling and crushing, conditions of longitudinal and transvers rebars, 10 damage levels are introduced. The factors of modification of stiffness, strength, and the acceptable range of ductility of the member (𝜆k, 𝜆Q, and 𝜆D) were proposed for each level of damage. The results show that almost across all damage levels, the damage grew with increased drift. Nonetheless, stiffness and ductility modification factors are constant during the first damage states; they decrease dramatically after the third damage state (DS4). However, the reduction of the strength decreased gradually as of the fourth damage state. the results presented in current research are more reliable estimation of reduction factors in comparison with current approaches.
