Concrete Structure Performance Assessment Of The Damage Mode

According to the pure flexural experimental result of model girder, This paper has analyzed beck beams girder and T girder which are ordinary adopted in bridge construction, founded experiential formula between cracking statistical parameter and sectional formula press area height, sectional curvature. Then we can calculate the steel ratio and stiffness of cracking section ,establish calculation model and analyze the structural ultimate carrying capacity, estimate the structural capability correctly. We hope this paper can speed up assessment of structural capability for highway bridges.
