【 摘 要 】

This paper presents a new type of brace system to strengthen transversal connection of T beam bridges. A nylon T beam bridge was made to study the strengthening effect. Braces were installed in the mid span and the load was symmetrical. The results show that the reduction of the maximum deflection of the bridge with the brace system was 14.9% in experiments and 19.1% in finite element analysis, which show that the transversal connection of T beam bridge can be improved efficiently by the proposed brace system.
