| Abstract: |
An analytical study was conducted to examine the differences in design and reinforcement effectiveness in patch plate reinforcement using high-strength bolts and studs. High-strength stud bolts, which were recently developed in Japan, allow for one-sided installation. From the obtained analytical results, it was found that the yield load of the high-strength stud bolt was 13% higher than that of the high-strength bolt because of the absence of cross-sectional defects in the main plate, and the rate of increase in slip load twice as large. In addition, it was shown that the thickness of the patch plate could be reduced by 11 mm, and the ratio of the load transmitted to the patch plate was also higher. It has been concluded that the usage of high-strength studs reinforcement is desired from the viewpoint of mechanical rationality and economical aspects. |
