On analysis of shear lag effect of thin-walled Box Girder
2020Co-Authors: Fang JuAbstract:The paper introduces the shear lag effect of the thin-walled Box Girder and its variation calculation methods,illustrates the process of the shear lag effect of the Box Girder of the variation calculation by combining with the cantilevel Box Girder of the factual bridge,and proves by the results that the influence of the shear lag effect can not be neglected in the bridge structure of the thin-walled Box Girder,so it can be the important factor influencing the design.

THE CONDITION OF WARPING CONTINUITY OF THIN-WALLED Box-Girder
Mechanics in Engineering, 2020Co-Authors: Zhang YuanhaiAbstract:On the basis of the theory of thin-walled member,the continuity of warping in analysis of bending shearing flow and warping shearing flow in thin-walled Box-Girder is studied.With the continuity condition of warping,the formula of warping shearing flow in restrained torsion of thin-walled Box-Girder is established.The error in relevent references is pointed out and corrected.The warping shearing flow in a cantilever Box Girder under restrained torsion is calculated.

ON ULTIMATE STRENGTH OF HORIZONTALLY CURVED Box Girder BRIDGES
1992Co-Authors: Hiroshi Nakai, Toshiyuki Kitada, Yasuo MurayamaAbstract:Presented in this paper is an experimental and analytical study on the ultimate strength of the thin-walled Box Girder with the longitudinal stiffeners subjected to bending and torsion. An experimental apparatus for applying both the bending and torsional moments to Box Girder specimens was newly developed. Through this experimental apparatus, the behaviors up to the collapse and the ultimate strength of these thin- walled Box Girder specimens with the longitudinal stiffeners were investigated. An interaction curve for the combined actions of bending and torsion at the ultimate state of curved Box Girders were also proposed. (A) For the covering abstract see IRRD 864118.

experimental study of full process of cfrp stress increment of prestressed concrete Box Girder
Natural Science Journal of Xiangtan University, 2011Co-Authors: Chi ShaojinAbstract:In this paper,the full process of concrete thin-walled Box Girder prestressed with external carbon fiber reinforced polymer sheets was tested.The regularities of stress increment variation of the external prestressing CFRP of concrete thin-walled Box Girder under different load levels are studied in details.Based on the analysis of the test results,the calculation methods for the stress increment of the external prestressing CFRP of the concrete thin-walled Box Girder at different loading stages are developed.The analytical results of the full process of the test agree fairly well with the field measurements.The reliable experimental basis will be helpful to the application of externally prestressed CFRP in concrete thin-walled Box Girder,which has important theoretical and practical value.
