The Study Of Reasonable Durability About Concrete T Beam Bridge

In recent years, with the use of concrete of T beam bridge there appeared a variety of diseases, which largely impacted on transportation safety and bring more to the country's economic losses, so it is very necessary to study reasonable durability of the reinforced concrete T bridge. In this paper, finite element software will be used to simulate the mechanical behavior of concrete T beam bridge, and then to study the durability of this structure in the general atmospheric environment, and last to propose a reasonable structure which combine the economic structure. This work includes the following aspects:(1)Investigate on the disease of concrete T beam bridge, then combine the study of domestic and foreign about durable concrete T beam bridge performance, and provide reference for the paper.(2)Analysis of various diseases about concrete T beam bridge and find reasons that causes the disease, and then find the way to solve the problem.(3)Using the finite element software to analyze and modeling the concrete T beam bridge structure.In-depth analysis of the impact on mechanical behavior of concrete T Beam Bridge by changing the T beam structure of the concrete T Beam, and a reasonable construction area will be got at last.(4)Based on the research of durability results of concrete bridge in the general atmospheric environment, studied the stress state and stress-free state about the durability of concrete T beam bridge respectively, and propose improving measures about the thickness of concrete.(5)Based on the analysis of Concrete T beam bridges'disease, study of other structural measures about concrete T beam bridge and find the deficiencies, and last find the way to improve.
