Topic: 43Abstract:
The objective of the research is to understand the behavior of bridge girders upgraded with post-tensioned near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) composites using a novel strengthening method, leading to the world's first field application of its kind. Numerical modeling is conducted to conceptually examine the performance of bridge girders with post-tensioned NSM CFRP in terms of flexural responses, strengthening configurations, and functionality. The feasibility of the proposed method is examined through a laboratory-scale test with an emphasis on anchorage installation, capacity improvement, and interfacial bond. All technical findings are integrated into the rehabilitation of a 40-year-old reinforced concrete girder bridge (L = 50 m, four spans).
