Abstract

This paper reports an experimental study on out-of-plane gusset welded joints strengthened with carbon fiber reinforced polymer (CFRP) sheets or plates. Weld toe radius and flank angle were measured with silicon based impression materials before fatigue tension test. Constant amplitude fatigue loadings were applied to 8 specimens with CFRP sheets, 8 specimens with CFRP plates and 5 specimens without reinforcement as the control group. Their fatigue lives and failure modes were observed. All cracks initiated from weld toes on the base plate that are adjacent to longitudinal plate ends. Fatigue lives of all the specimens, which were plotted in S-N graphs, were above the fatigue design F-class curve recommended for steel structures (Japanese Society of Steel Construction). Fatigue life was extended to some extent although scatters were observed in the test results of strengthened specimens. Possible explanations are discussed in the paper and future work is pointed out.
