| Abstract |
This study conducted the steel plate reinforced experiment considering decay and damage of hip rafter in the traditional wooden structure building and found the following behavioral and reinforcement effects. As a result of hip rafter experiment, it was found that steel plate reinforced specimen applicable to the decay and damage of hip rafter showed generally the increase of yield load by 80.5～222.5% and that of initial stiffness by 8～40%. Reinforcement using inserted 'T'- or double 'T'-shaped steel plate was more effective in enhancing structural reinforcement than using ‘一’ letter form in upper part of hip rafter. To sum up the experimental results of this study, it is expected that the reinforcement using inserted 'T'- or double 'T'-shaped steel plate to the hip rafter of traditional wooden buildings can result in effects of enhancing initial stiffness, yield load and deflection control. In addition, further studies on mitigating stress concentration due to the combination of steel plate and bolt in steel plate reinforcement of the traditional wooden structures will be required. |
