Safety Evaluation of Reinforced Concrete Girder Bridge after Strengthened with Pasting Technology
This paper examines the load capacity and safety of reinforced concrete beam bridge strengthened with pasting steel plates and carbon fiber polymer technology, taking the Longwanggou Bridge built in Jungar Qi in 1980s,a coal-rich area in Inner Mongolia, for example, in accordance with the Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts (JTG D62-2004), and the Code for Design of Highway Bridge Strengthening (JTG /T J22-2008). The girders in superstructure of this bridge were strengthened by using pasting steel plate technology, while the capping beams of piers and abutments using combined technology of sticking steel plates and carbon fiber reinforcement polymer (CFRP). At the same time, the deck pavement and the expansion joints were replaced, with adjusting the continuous form of the bridge, to improve the integrity and its driving comfort. The results from the theoretical analysis and dynamic and static load tests on the bridge after strengthening have shown that it is safe and good in the integrity and reliable in the load capacity.
