内容記述 | In this study, the analytical evaluation was conducted in order to evaluate the mitigation effect resulting from various retrofitting methods on ASR expansion. Through the investigation by means of Finite Element Analysis, ASR expansion model proposed by authors was applicable to evaluate the ASR expansive behaviors of RC columns retrofitted by steel plate bonding method and PC confined method. The parametric analyses were also conducted in order to evaluate the mitigation effect retrofitting on ASR expansion. As the results, it was quantitatively confirmed that the introducing lateral force such as PC confined method was more effective for mitigating ASR expansion than the retrofitting with high reinforcement ratio. | |||||
