Ultimate Flexural Bearing Capacity Research Based on Carbon Fiber Sheet to Reinforce Rough Sleeper Beam

摘要

In this paper, it makes a preliminary study on the material of carbon fiber sheet to reinforce rough sleeper beam in order to enhance the magnitude of ultimate flexural bearing capacity.Considering the actual construction technology and environment, four reinforced concrete sleeper beams are used to experiment simulation to study the influence of carbon fiber sheet to ultimate flexural bearing capacity of reinforced concrete structures.Experiment results show that pasting two layers of carbon fiber sheet under reinforced concrete beam can have about a 25％ increase in flexural bearing capacity.
