Abstract


Composite beams with corrugated steel webs is a new type of steel - concrete composite structure , has been widely used in Japan and Europe and the United States due to its good performance of the force , which is characterized in that it takes full advantage of the material advantages of concrete and steel . This structure can achieve the main beam of light , and thus reduce the number of the lower part of the structure of the project . This paper first describes the overview of the development of the box girder bridge with corrugated steel webs , the structural system structural features (including the shape of the corrugated steel webs and shear connector type , etc.) , as well as the structure of the force characteristics . According to the structure of the research status at home and abroad , the main content of this paper . Corrugated steel webs this paper abroad analysis results and built bridges , steel webs under the real bridge trapezoidal waveform behavior , including corrugated steel webs axial deformation and local buckling the mechanical characteristics of the overall buckling , synthetic buckling stability . Finite element software ANSYS, the paper analyzes corrugated steel webs PC combination of curved box girder bridge mechanical characteristics : ( 1) by an instance of the finite element calculation results with the experimental results compared to verify the correctness of the modeling analysis method in this paper . ( 2) the use of finite element analysis software ANSYS, contrast curved box girder bridges , corrugated steel webs PC combination with traditional PC curved box girder bridge mechanical properties . ( 3 ) analysis of different radius of curvature , the bearing eccentricity diaphragms arrangement Corrugated Steel Web PC Composite curved box girder bridge deformation force .
