Abstract

This study investigates the effect of certain parameters on the magnitude of plastic hinge length of RC shear walls and proposes an analytical expression for estimating the plastic hinge length. A finite element model was analyzed and validated with experimental test results for an existing study and a parametric study was performed for it. The established results were according to several parameters such as axial load ratio, slenderness ratio and wall length. The numerical results showed a different impact of these parameters on the formation of the plastic hinge length. In this study, a new simple expression was derived based on those parameters using statistical package software. Proposed plastic hinge expression was compared with the results of the plastic hinge length obtained from FE analysis. Finally, the accuracy of the proposed equation was validated by using the shear wall results from the literature researches.
