Plastic Performance Test and Finite Element Analysis on the Concrete Continuous Beams Strengthened with CFRP Sheets
摘要
Abstract
In order to study the plastic properties of the concrete continuous beams strengthened with CFRP sheets, three two-span continuous beams were fabricated and the control sections in the mid-span of the test beams were strengthened with CFRP sheets.Static test was carried out on the test beams with two-point loading type.The test data such as load, crack distribution and deformation were obtained in different loading stages.Based on the test data, the finite element analysis on the continuous beams strengthened with CFRP sheets was carried out by ANSYS software.The variations for steel stress and deflection of control section in the intermediate support as well as the bearing capacity in different stages were obtained.The results show that the bearing capacity of the continuous beams strengthened with CFRP sheets has not been distinctly improved under elastic state while the ultimate bearing capacity has been significantly increased under plastic state, and the continuous beams displays internal force redistribution obviously.关键词
