Abstract

Abstract

Combination strengthening RC beams with CFRP and steel plates is a new method. Through the test of one reference beam and six strengthened beams,it is indicated that the flexural capacity and ductility of combination strengthened beams are superior to carbon fiber strengthening and steel-bonded reinforecment and the initial load has not obvious effects on its load capacity. Furthermore,the failure mode and the increased limit value of the flexural capacity in combination strengthened beams are analyzed based on experimental results. The analysis shows that the increased limit value of combination strengthened beams is much more than 40% of concrete specifications,and combination strengthened statisfying the requirements for its service performance. Therefore if there is a need to both enhance bearing capacity to a greater extent and statisfy service performance of a flexural member,it is recommended that combination reinforcement should be used.
- combination strengthening,
- carbon fiber,
- steel plate,
- flexural capacity,
- improve limit value
