Study on the Dynamic Performance of a Bridge Reinforced with CFRP Plates

Abstract

Using carbon fiber reinforced polymer (CFRP) plates is currently an effective technique for bridge reinforcement. This study fully introduces a dynamic performance test of a bridge reinforced with pre-stressed CFRP plates, including a structural modal test, moving vehicle test, braking test, and bumping test. The dynamic displacement, dynamic strain, and related impact effects of the structure were monitored, which demonstrated the high effectiveness of prestressed CFRP plates in reinforcing bridges. Relevant findings and data provide a reference for the dynamic testing of similar bridges.
