本研究旨在評估國內生產的柳杉製成的直交集成板(Cross laminated timber, CLT)開口剪力牆在耐震補強和新建工程中的應用潛力。考慮到台灣許多現存建築物採用非韌性結構，面對地震時常出現結構損壞。傳統耐震補強方法可提升建築安全，但常對居民日常生活造成干擾。本研究以CLT為基礎的剪力牆系統，特別是設計了具有開口的剪力牆以適應建築物內部空間需求和美觀要求。
本研究係延續先前國產之直交集成板（CLT）進行非韌性RC建築物耐震補強可行性之研究，針對開口CLT剪力牆進行耐震補強及新建工程，檢討結構耐震能力。實驗試體包括四組，分別為中央開口CLT補強試體(編號MR)、柱邊開口CLT補強試體(編號SR)、中央開口CLT新建試體(編號MN)及柱邊開口CLT新建試體(編號SN)。實驗結果顯示，MR試體最大水平剪力為627.55 kN，最大層間位移角為6%，SR試體最大水平剪力為806.56 kN，最大層間位移角為6%，MN試體最大水平剪力為744.20 kN，最大層間位移角為6%，SN試體最大水平剪力為821.45 kN，最大層間位移角為4%，皆滿足含牆結構2%變形要求，雖相較於無開口CLT剪力牆減少了20%-30%水平剪力強度。但仍提供4%-6%層間變位角，有效提供既有建物及新建工程之耐震性能。

This study aims to evaluate the potential application of cross-laminated timber (CLT) shear walls with openings, made from domestically produced larch, in seismic retrofitting and new construction projects. Considering that many existing buildings in Taiwan are non-ductile structures, they often suffer structural damage during earthquakes. Traditional seismic retrofitting methods can enhance building safety but often disrupt residents' daily lives. This study focuses on CLT-based shear wall systems, particularly designing shear walls with openings to accommodate the internal spatial and aesthetic requirements of buildings.
Building upon previous experiments with domestically produced CLT, this research examines the seismic retrofitting and new construction of CLT shear walls with openings. The seismic capacity of the structures was evaluated through experiments on four groups of specimens: centrally opened CLT reinforced specimen (MR), edge-column opened CLT reinforced specimen (SR), centrally opened CLT new construction specimen (MN), and edge-column opened CLT new construction specimen (SN). The experimental results showed that the MR specimen had a maximum horizontal shear force of 627.55 kN and a maximum interstory drift angle of 6%. The SR specimen had a maximum horizontal shear force of 806.56 kN and a maximum interstory drift angle of 6%. The MN specimen had a maximum horizontal shear force of 744.20 kN and a maximum interstory drift angle of 6%. The SN specimen had a maximum horizontal shear force of 821.45 kN and a maximum interstory drift angle of 4%. All specimens met the 2% deformation requirement for wall structures, despite a 20%-30% reduction in horizontal shear strength compared to CLT shear walls without openings. However, they still provided 4%-6% interstory drift angles, effectively enhancing the seismic performance of both existing and new buildings.
