崙坪文化地景園區擁有豐富森林綠帶，在永續循環發展理念下，從森林中樹的落葉為概念，讓此落葉歸根的構想，輕輕地落在崙坪文化地景園區的一角。透過可永續循環的木材成為本案最核心的結構系統與材料，並運用先進營建膠合木構技術的特殊工法，詮釋嶄新的開放性木構棚設施，促使使用者可以透過五感體驗，感受到空氣、陽光及雨水的開放性公共空間，並與周邊的大樹林相融合，成為本園區的地景入口地標。
本案主體結構採用木鋼混合構造，以「短向主圓拱、長向龍骨」作為主要之抗側力系統，垂直力方向則考量長向桿件上下交疊之結構加成效果。
設計力考量
依木構造建物設計規範規定，考量地震力與各向風力載重組合最大需求，並依據結構分析所顯示之受力分布進行區域性加強，以達到設計之經濟性。
風力設計
本案屬開放式建築，依據耐風規範，應詳加計算建築物側向、向上及向下設計風壓同時組合作用之最不利工況。
屋面設計與變形控制
屋面由柳杉塑化木與檁條組成，其中檁條採用柳杉實木條，為達成結構特殊造型曲線之精準，減少實際結構變形之不利影響（前端懸臂跨度達約7.6米，中段簡支跨度達約十九米），主要構件施予預拱及無重力全支撐方式施工，以使結構最終造型能符合建築師要求。此外，結構外圍懸臂樑區域特別針對局部檁條（purlin）進行再加強，以避免變形過大。
基礎設計
以聯合基腳為主，以三處聯合基腳承載上部結構之受力，考量拱形結構外推力，增設繫樑或加大承受被動土壓結構牆，增加結構之穩定性，將受力有效傳遞至土層。
接合細部設計
上部主結構落地與基腳接合採螺栓接合，木構與鋼板儘量採用隱藏式接頭，確保鋼構轉換有效性，以達到木構外觀保持最大完整性與一致性。
Lunping Cultural Park boasts a green belt with diversified forestscape. Grounded on the principle of sustainable development and circular economy, the concept is that of a fallen leaf from the forest returning to the ground as it gently descends on a corner in the Park. Wood, a sustainable material, is the dominant material used throughout the project including in the structural system. Advanced laminated wood technology is applied to represent the novel open-style canopy, where the user is treated to a sensory experience of the air, sunlight and rain in the open public space. The structure, complemented by the surrounding forest, forms the entry gesture to the Park.
The primary structure combines wood and steel components. Lateral resistance is predominantly provided by the central arch in the short axis and the backbone in the long one, while vertical overlapping of the longitudinal bars provide synergetic forces in the vertical direction.
Loading force design
The design code for wood structures is followed, maximum requirements from the combination of seismic forces and wind loads in various directions are considered, and local reinforcement is added according to load distribution from the structural analysis in order to achieve economics in design.
Wind resistance design
This project is categorized as an open structure, and according to the code requirements for wind resistance, worst-case scenarios must be calculated by considering the simultaneous combination of lateral, upward and downward wind pressure.
Roof design and distortion control
The roof is composed of plasticized wood and purlins made from common cryptomeria wood. To achieve precision for the special curvilinear structure and reduce negative impact from structural distortion (the front cantilever is approximately 7.6 m, and the central span is approximately 19 m), the main structural members are pre-cambered and constructed with gravity-free full support so as to ensure the final structural form matches the architect's requirement. In addition, purlins near the exterior cantilevered areas are specially reinforced to limit distortion.
Foundation design
The primary design is combined footing, with three combined footings bearing the forces from the structure above. In consideration of the outward pushing forces of the arch structure, a tie beam is added or the structural wall bearing the passive pressure from earth is increased to enhance the structural stability and effectively pass the forces down to the ground level.
Joint detail design
The primary structure above is connected to the footings using bolts. Concealed joints are used wherever possible for the wood structure and steel plates to ensure effective conversion in the steel structure, achieving maximum integrity and consistency in the appearance of the wood structure.
