為了方便結構設計及現場施工下，高強度鋼筋的使用需求日益漸增，過去幾年國內外均有許多學者致力研究高強度鋼筋於不同鋼筋混凝土構件使用的可行性，然而實驗大多以靜態方式進行測試，對於承受動態作用下之行為並不清楚，為能更了解使用高強度鋼筋之鋼筋混凝土構件於地震下的反應，本研究設計並測試兩座使用不同降伏強度鋼筋之單跨單自由度構架試體，先於振動台上同時進行十六組動態的地震歷時測試，接著移至反力牆進行靜態往復載重試驗。動態試驗結果顯示使用降伏強度為717 MPa(104 ksi)之高強度撓曲鋼筋試體H1所得最大變形量在所有地震歷時下均大於使用降伏強度453 MPa(65.6 ksi)之普通強度試體C1，整體而言試體最大變形量比介於1.33 到 2.27之間。兩座試體的側向勁度隨著地震反應下最大位移增加而降低，試體C1的殘餘側向勁度可以透過地震反應下最大位移和對應在兩個加載方向上的基底剪力所形成的割線斜率來估算，相同的方法應用於試體H1時僅有在經歷小至中等地震下適用。當試體進入非線性反應後，測試結果顯示使用割線勁度之Shimazaki與Sozen模型合理提供試體C1非線性最大位移評估的上限值，但該模型所得結果對試體H1並不適用。

To facilitate the on-site construction without compromising the structural strengths or section sizes, the demand of using high-strength steel reinforcement has increased substantially in the past few years. The past experimental works to study the potential of using high-strength reinforcement in different reinforced concrete (RC) elements were mostly conducted under cyclic or monotonic static loading. Dynamic test on RC elements using high-strength reinforcement is very limited. In order to further understand the dynamic response of reinforced concrete structures using high-strength longitudinal reinforcement, two RC frame specimens were tested in this research. The columns of specimen C1 and H1 were designed to have the same nominal flexural strength using longitudinal reinforcement with yield strengths of 65.6 ksi (453 MPa) and 104 ksi (716 MPa), respectively. Specimens were subjected to a total of 16 ground motions on the shake table, followed by quasi-static test. The dynamic test results indicated that specimen H1 consistently exhibited larger drift than specimen C1 when subjected to a similar ground motion. Overall, the ratio of maximum drifts between H1 and C1 ranged from 1.33 to 2.27. The lateral stiffness of the two specimens decreased as the maximum drift induced by the ground motion increased. The residual lateral stiffness of specimen C1 can be reasonably estimated as the slope between the maximum positive and negative drifts on the foundation force-drift response. However, the residual stiffness in specimen H1 tended to be lower than the secant stiffness from the foundation force-drift response after a few ground motions. For nonlinear drift estimation, the model proposed by Shimazaki and Sozen (1984) using the secant stiffness provided an adequate upper limit for nonlinear displacement of specimen C1, but underestimated the nonlinear displacement of H1 for some ground motions.
