本研究設計了六座對台灣低矮型建築具代表性之含開口鋼筋混凝土牆非韌性構架試體，於國家地震工程研究中心（National Center for Research on Earthquake Engineering, NCREE）進行試驗。共規劃三個系列，每個系列各二座試體：單一開窗試體、雙開窗試體以及單一開門試體。實驗結果顯示，開窗寬度較小的試體，因保有翼牆的特性，其翼牆能讓剪力強度明顯提昇。雙開窗試體，於兩開窗中間的垂直牆段，其強度的貢獻，與其高長比有明顯的差異。而單一開門系列的試體，其開門上方所增加的垂壁，對試體的剪力強度提昇效果不大，但會因開門兩側垂直牆段的高長比，明顯影響試體的韌性表現。關於含開口鋼筋混凝土牆的剪力強度計算，ACI 318-14規範中已有明確的計算公式，本文利用ACI 318的建議公式來計算剪力強度並與實驗值作比較，以驗證ACI 318-14規範針對含開口RC牆的剪力強度預測之適用性。

In this study, six specimens of non-ductile RC infilled frames with openings were designed according to the typical low-rise buildings in Taiwan, and these specimens were tested in NCREE. Specimens were categorized into three series, such as single window opening, double window openings and single door opening, and each series has two specimens. Test results indicated that the smaller width of window opening can increase shear strength significantly due to the contribution of wing wall. For the specimens of double window openings, shear strength of vertical wall segments between two window openings is significantly lower as compared with its height-to-length ratio. For the specimens of single door opening, the experimental results showed shear strength only increased slightly by its overhanging wall. In addition, it was indicated that the ductility of the specimen is significantly improved because the larger vertical dimension of door opening can yield higher height-to-length ratio of vertical wall segment. ACI 318-14 building code has equations to predict the shear strength of RC wall with openings. In this paper, ACI 318 building code was used to calculate shear strength and compared with the experimental results to check the applicability of ACI 318-14 code on predicting the shear strength of RC wall with openings applicability.
