Bearing Capacity Evaluation of RC Beam Bridge Based on Crack Index

Abstract:

Using crack to evaluate the bearing capacity of RC Beam Bridge is an effective method. This paper puts forward using the crack spacing, width, height and their statistical weights to characterize the structural crack index and using Analytical Hierarchy Process to get crack index expression. After a lot of survey analysis of actual cracks, get corresponding relation between crack index and the checking coefficient of their bearing capacity, then through structure resistance expression to check structure, finally the assessment of the bearing capacity of the bridge was got. With a simply supported T beam bridge as an example, the result shows that this method is reliable, simple and economical.
