Abstract
The research on the retrofitting method using the concept of integral abutment bridge to solve the durability problems of simply supported bridges was carried out. The general retrofitting process adopted by real projects and the mechanical properties increment after retrofitting were summarized. A simply supported bridge in Italy was analyzed numerically using finite element model built by SAP2000 with inclusion of soil-structure interaction. The influence of old and new Italian codes on the mechanical properties of different static schemes, including simply supported, semi-integral and fully integral, was investigated.
