The objective of this study is to clarify the load carrying and the deformation capacities of circular hollow section steel members, reinforced with carbon fiber subject to compression or combined bending and sheering. In order to this, stub column and beam-column tests are carried out. The test parameters are the width-to-thickness ratios, reinforcement ratios, and reinforced length. The results obtained are as follows; 1) Due to the effect of carbon fiber, the local buckling mode in the area, reinforced with carbon fiber, is diamond-type. 2) The load carrying and the deformation capacities of circular hollow section steel members reinforced with carbon fiber increased when reinforcement ratio increased. 3) In case of beam-column, the reinforced length has influence on the position which occurred local buckling. In addition, it has influence on the deformation capacities of beam-columns
