Existing Concrete Girder Bridges' Bending Stiffness Assessment Based on Crack Characteristics Parameters
A lot of existing reinforced concrete girder bridges appeared cracks in the service phase. Because of the beam's cracks existing, the sectional bending stiffness of the beam decreased. It would reduce the structure's bearing capacity, so the bridges' structure performance urgently needs to be assessed by effective methods, so as to study further measures. In this paper, based on the indoor model test results of four pieces of model beams, regression analysis of the crack characteristics parameters and test's load-displacement curves has been carried out. The relationship between crack characteristics parameters and girder bridge's bending stiffness has been established. The qualitative assessment of structure crack's appearance inspection is transmitted to quantitative assessment, so it will make the assessment more objective and scientific.
