dc.description.abstract鋼筋混凝土剪力牆為公認之優秀耐震構材之一,能有效增加水平向承載能力,使其在側向更具韌性。傳統型剪力牆系統通常配置在核心部分作為抗側力系統,但是由於美觀或實際需求,剪力牆系統經常需要設置門、窗等,故而對剪力牆開孔,所以剪力牆常使用延展性與能量消散較佳的連接梁(Coupling Beams)做連結,並期望塑角發生在連接梁端部與剪力牆底部,降低剪力牆其他區域損害程度,以維持耐震機制,形成連接式剪力牆系統。但由於美國規範ACI 318-14規定跨深小於2之連接梁需配置滿足規範型式之對角鋼筋籠,因其對角鋼筋籠之型式容易造成施工困難,導致施工品質不佳;且於規範之連接梁標稱剪力強度及上限值有過於保守趨勢,造成工程師不易設計合適之連接梁。另外,為了滿足高樓RC建築所需之高規格的耐震強度,採以部分材料使用新型高強度材料,並嘗試不同對角配筋型式,期望有效的使用高強度材料,藉此減少材料用量,提高環保意識。   本試驗共設計五座跨深比為1.5之連接梁試體,經由雙曲率與零軸壓之狀態下進行反覆載重試驗,在不同之對角鋼筋降伏強度及對角配筋型式變化下,探討新型高強度材料應用於連接梁之情形,並針對美國規範ACI 318-14對於連接梁之對角配筋型式及標稱剪力強度進行探討與檢核其必要性。   試驗結果顯示高強度材料應用於跨深比為1.5之連接梁時仍展現極限層間位移大於6%之位移能力,而對角束筋型式為可行之配筋方案之一,另外,使用高強度對角鋼筋可有效降低鋼筋比,改善施工問題,並展現相當良好之耐震行為。zh_TW
dc.description.abstractDuctile coupled shear wall is the best seismic girders, the results of the seismic is outstanding, making the structure of the building effective against devastating earthquakes. It is advantage is the increase of the building is resistance against horizontal shear force.   Because of the need of underground parking lot, holes are needed to be drilled through ductile couple shear wall for the use of stairwells, passages, and elevators. So the ductile couple shear walls system is needed to be connected by coupling beam to fulfill the needs of space. However, due to the provisions of ACI 318-14, the aspect-ratio of coupling beams is less than 2 must be configured to meet the specification of the design of diagonal bars cage. It will lead to in poor quality of construction because the complex construction of diagonal bars cage. And the nominal shear strength and its upper limit of ACI 318-14 are too conservative, engineers difficult to design an appropriate coupling beams. In addition, in order to meet the seismic intensity of the requirements in high-rise RC building, part of the material use the new high-strength materials, and try different designs of diagonal bars, expect effective use of high-strength materials, thereby reducing the amount of material, and raise environmental awareness.   In this study, five reinforced concrete coupling beams which aspect-ratio is 1.5 are made as specimens. The experiment was carried out through the morph of dual-zone rate and the condition of without applying axial force after cyclic loading test and analytical methods to investigate diagonal reinforcement in different yield strength and design of diagonal bars, and to observe the situation of the new high-strength material used to coupling beams. In addition, this study also checked the type of diagonal bars and nominal shear strength under the specification of ACI 318-14.   The test results show high strength coupling beams which aspect-ratio is 1.5 still show more than 6% ultimate drift ratio, and coupling beams with bundled diagonal bars is one of feasible type of diagonal bars, in addition, the use of high strength diagonal bars can reduce reinforcement ratio, improved construction issues, and show quite well the seismic behavior.en_US
