(1 Liaoning Technical University, Fuxin 123000, China ;2 Dalian University of Technology, Dalian 116024, China; 3 FuXin Power Plant, Fuxin 123001, China)Abstract: The finite element analysis on beams pressed with dead loading of trestle for coal transporting of Fuxin Power Plant was completed by using ANSYS software. The result shows that the carrying power ofbeam reinforced with CFRP is increased and deflection is controlled effectively. At the same time, analysis on respond history of the factory building excited by dynamic shows that the mass of structure increase so little that can be ignored by means of pasting CFRP for reinforcing structure, and resistance to lateral bending stiffness is increased dramatically, so that the structure can resist any loading.
Keywords: CFRP; reinforcement; beam; concrete
