| Abstract: | This paper compares the bending performance of U-type steel-encased concrete composite beam,H-shaped steel beam and steel reinforced concrete composite beam through ABAQUS,points out the difference of bending bearing capacity among three kinds of composite beam,discusses the influence of concrete strength,steel yield strength and thickness of steel plate on the bending performance of composite beam and puts forward methods of matching of materials of different grades.On the basis of these,we can obtain the using of condition of three kinds of composite beam and control parameters reasonably to achieve the purposes of economics and fitness. |
