Abstract
A strengthening method for old steel railway bridges by using rubber-latex mortar, GFRP plates, lightweight rapid hardening concrete, and reinforcing bars was introduced in this paper. The present method was used to strengthen an old steel railway bridge that has been used for 61 years, and field tests were performed on both strengthened and un-strengthened bridges to confirm the real effects of this strengthening method. Both experimental and numerical results indicate that the present renovation method can greatly enhance the stiffness and reduce the stress levels of steel members, resulting in the extension of the residual service life of the old steel railway bridge.
