| Abstract: | Taking the engineering of strengthening a simply supported T-shaped beam bridge as an exam-ple, the paper analyzes the mechanical property of T-shaped beam bridge by the finite element software named Midas Civil, as well as the changing rules of the stress of diaphragms and main beams, the structur-al improvement factor and the transversal uneven amplifying coefficient of T-shaped beam bridge with the different location of additional diaphragms. Finally, the optimal location of diaphragm is confirmed. |
