Constitutive Relationship of FRP Reinforced Column Plastic Hinge Zone Based on Pushover Analysis

Abstract:

The formation and development of plastic hinge is the basis of the whole process of FRP reinforced concrete eccentricity compression and flexural member nonlinear analysis. The moment-rotation relationship of FRP reinforced rectangular column plastic hinge zone was studied. Its yield and ultimate moment formulas were proposed. The specific values of the moment and rotation were discussed in different modes of failure, retrofitting methods as well as FRP types. A constitutive relationship of FRP reinforced rectangular column plastic hinge zone was established. Based on the constitutive relationship, a pushover analysis of the numerical model is conducted, and the feasibility of its application in Etabs software through cases is verified.
