本研究旨在探討使用高強度鋼筋於低矮型鋼筋混凝土剪力牆的可行性，以及規範對低矮型鋼筋混凝土剪力牆之特殊邊界區圍束箍筋要求之有效性，本論文共測試五組低矮型鋼筋混凝土剪力牆，試體斷面積一致為8 in. "×" 80 in. (200 mm "×" 2000 mm)，試體以單曲率單向往復載重方式測試，其中剪力跨距與試體長度的比值均為1。本研究使用的高強度鋼筋為SD785，其標稱降伏強度約為115 ksi (805 MPa)。實驗結果顯示使用高強度鋼筋之試體，其強度及位移能力與符合ACI 318-11規範之普通強度鋼筋(Grade 60)試體相當。根據規範ACI 318-11所設計之試體，無法避免剪力主控的破壞模式。試體的極限變形能力和剪應力強度成反比；當剪應力需求上升，變形能力則會下降。此外，邊界特殊構材的箍筋間距對高剪力需求試體的極限剪力強度及極限變形能力的影響有限。

This study investigates the potential of using high-strength reinforcement and effectiveness of confinement required in the special boundary element by ACI 318-11 in reinforced concrete (RC) squat shear wall subjected to cyclic displacement reversals. A total of five specimens are tested. All specimens have an identical cross section of 8 x 80 in. (200 x 2000 mm) and a shear span-to-length ratio of 1.0. The selected high-strength steel has specified yield strength of 115 ksi (805 MPa). Test results indicate that specimens using high-strength steel exhibit comparable strength and deformation capacities as specimens using conventional Grade 60 steel. Shear capacities based on the code provisions cannot prevent the shear wall specimens from shear-governed failure modes. Specimen ultimate deformation decreases as the induced shear stress level increases. Additionally, strength and deformation capacity are not greatly influenced by the reduced amount of confinement in the special boundary region.
