Abstract

Abstract

In order to study initial stress and ring force transfer between steel plates and concrete in the numerical analysis of RC beam strengthened by bonding steel plates, 8 scale-down models of RC beam were manufactured, their loaded whole processes were analyzed by using surface-surface contact analysis method and "birth and death" element method, and a numerical analysis method of strengthening RC beam with initial stress was proposed.Numerical analysis result shows that the deflection variation rule is consistent with its test rule, the deviation is within 11.5% in ultimate load case.Obviously, it effectively solves the problems that retrofitting structure and steel plates don't act together and how does the force transfer between concrete and steel plates in preloaded case.
