本論文為利用國產柳杉集成材，進行足尺集成材單柱與續接集成材單柱之耐震性能研究，其中木構造接合系統機制為楊書河學長於2024年攻讀博士期間，在劉光晏副教授的指導下所提出，包括單柱系統、單柱續接系統、單層構架系統、雙層構架系統，並於2025年提出專利申請，之後由BEER Lab研究團隊進行實驗與驗證。
本研究驗證一種具備大變位承受能力，與自復位性能之創新木結構接合機制，不同於傳統螺栓接頭通常將螺栓垂直於受力方向安裝，本研究將全牙螺栓之鎖固方向與受力方向平行。系統在受側向力作用下，藉由金屬組件優先於木材發生降伏與變形，建構穩定的抗力機制並維護木材構件之完整性。此外，本研究驗證此新型單柱續接方式，透過全牙螺栓與結構膠結合以確保有效之應力傳遞。實驗結果顯示，續接試體在大變位條件下仍能維持結構完整性並展現穩定之遲滯響應，確保損傷受限於可更換之金屬零件。
試驗結果顯示，本系統具備優異之變位容許量與穩定之消能行為。當層間位移角達到3.89%時，結構強度未出現明顯退化，且損壞集中於可更換之金屬組件內，有效維護木材構件之完整性。在自復位性能方面，殘餘位移角普遍控制在1%以內，證實系統具備良好之自復位潛力。此外，續接試體之應變分佈與遲滯迴圈與連續試體高度重合，證實該續接界面能確保有效之應力傳遞，具備支撐垂直增建之潛力。
本研究共製作6組足尺試體，進行9次試驗，包含模擬餘震情境之重複加載。研究證實，透過更換金屬組件，結構性能具備高度可恢復性。此接合機制不僅克服了傳統木構造接頭易因局部劈裂而導致勁度降低，更為國產材之永續應用與耐震韌性建築提供具備實務推廣之價值。

This thesis investigates the seismic performance of full-scale and spliced glulam columns using Taiwanese-grown Cryptomeria japonica. Based on a connection mechanism proposed by the BEER Lab research team, this study introduces an innovative joint that aligns fully-threaded bolts parallel to the loading direction, rather than the traditional perpendicular orientation. This design facilitates a "damage shielding" effect where metal components yield before the timber, maintaining the structural integrity of the wood members. A novel splicing method utilizing fully-threaded bolts and structural adhesive was also developed to ensure effective stress transfer.
Experimental results from nine tests on six full-scale specimens, including repeated loading scenarios, demonstrate superior displacement capacity and stable energy dissipation. At an inter-story drift ratio of 3.89%, the system exhibited no significant strength degradation, with damage concentrated solely in replaceable metal parts. The system showed excellent self-centering potential, with residual drift ratios maintained below 1%. Moreover, the hysteretic response and strain distribution of the spliced specimens highly coincided with those of the full-scale specimens, confirming the splicing interface's efficiency and its potential for vertical structural extensions.
The research concludes that structural performance is highly restorable through component replacement. By overcoming the local splitting and stiffness degradation common in traditional timber joints, this mechanism offers practical value for the sustainable use of domestic timber and the advancement of seismic-resilient construction.
