<p>This paper proposes reinforcing methods for bolt holes defects in SC grade beams. The strength of SC grade beams decreases by about 30% due to bolt holes defects in column base joint. Two types of reinforcing method are devised: One is reinforcement by L-shaped steels and the other is by channel steels and deformed bars. The availability of proposed methods was confirmed by full-scale tests. The strength of the reinforced SC beams is almost equal to the SC beam without defect. The calculated strength by cross-section analysis agrees with the experimental results well.</p>
