This paper describes a method of performance evaluation and remaining life prediction for an aged reinforced concrete (RC) T-girder bridge by J-BMS RC version via close visual inspection data, and also verifies the assessment results obtained as outputs from the Bridge Rating Expert System (RC-BREX) which is a subsystem of the J-BMS, to evaluate the effectiveness of the system. The Bridge Manag...

Evaluating the aerodynamic instability of a bridge girder fitted with attachments such as handrails is critical for wind-resistance design long-span bridge. However, effects detailed configuration on performance have not been sufficiently studied. In this study, heaving vortex-induced vibration (VIV) box-girder was evaluated nongrid and grid-like handrail cases by free wind tunnel tests. The VI...

Aiming at the problem of cable breakage an asymmetric single-tower cable-stayed bridge by taking a that has been in operation for more than 20 years as engineering example, spatial finite element model reflected actual stress state structure was established and method solving time point proposed. The results show strength main girder, pylon could meet requirements vibration caused successive br...

This manuscript studied the effect of U-CFRP wrapped sheet anchorage on flexural performance unbonded post-tensioned PC members subjected to partial strand damage and strengthened using CFRP Near-Surface Mounting techniques. The program includes six girders as a control girder, girder with 14.2%, four by laminates NSM technique without anchorages. testing results show that 14.2% has reduced str...
