The assessment formula for shear capacity was established as well, and in which various impact factors of shear strength was considered comprehensively.3. Directed against the main forms of transverse connection in concrete beam bridges, model test and finite element analysis were carried out to find the impact laws of damage on concrete T-beam bridges, in which the three ways of hinged joint, flange rigid connection and cross slab rigid connection were considered. Transverse distribution and degenerate state of transverse connection were studied under various damage conditions. Based on the analysis of test and simulation results, the rule of live load adjustment coefficient of T-beam bridge was put forward, as well as the calculation formula.4. In view of the influence of the damaged transverse connections to load effect, the load effect model was amended by live load adjustment coefficient.
