BUCKLING CONTROL METHOD USING UNBONDED FRP FOR STEEL PLATE

Abstract

In this study, a stiffening method to improve the buckling resistance of steel plates under compressive loading was investigated using an unbonded FRP, which is an effective method against buckling and unstable phenomenon in structures. The buckling behaviors of the steel plates were analyzed by experiments and mechanical modeling. As the results, it was made clear that the compressive strengths of the steel plates with unbonded FRP stiffener can be evaluated by the design method. Moreover, it was shown that the post-buckling load-deflection behavior can be reasonably estimated by the proposed mechanical model.
