Abstract: It was conducted the construction monitoring and load test of the national first highway concrete bridge externally prestressed with CFRP tendons,the test results show that concrete cracks can be eliminated or reduced significantly produced at the stage of frames removal,and thus the service behavior of girders are improved due to tension of CFRP tendons.In each test case,girders performed elastically with its strain varying at a linear phase;moreover,the testing force increment of external CFRP tendons was consistent with the theoretical values.All these suggest the concrete girder and external CFRP tendons may serve together in a good pace.In addition,no wear signs and any other defects have been founded at the shift block as well as the anchors.Therefore,all these proved that external prestressed CFRP tendons with a fold line layout can be applied for concrete girders with a good performance.
