Abstract
臺灣地區已廣泛使用溫室進行花卉及蔬果作物栽培，然地理環境影響常有強風侵襲，對於結構耐風能力不足情況下，常使設施損壞，因此適度提昇設施結構耐風能力，降低固定資本之損失。本研究以建築物耐風設計規範及有限元素分析軟體，進行溫室結構耐風能力分析，作為適度耐風能力提升之設計參考，以對照組及補強模組進行分析，結果顯示，內部無橫向桿件支撐外部結構情況下，在承受側向風力作用時，僅由主骨架組及桁條向骨架所承受，變形量皆較補強模組為大，而內部增加補強結構時，三種補強模組之試驗結果顯示，V形補強模組變形量為最低，抑制幅度可達39.3 %，山形模組為三種補強模組中次低，抑制降幅約33.4 %，倒T形模組，抑制降幅約20.9 %，為補強模組中最低，三種溫室設施內部補強模組，可分擔及傳導受風應力，並且可提升溫室結構整體的鋼性，減少骨架位移的發生，皆可有助於耐風能力的提高。
Greenhouse is widely used to grow crop, Low wind-resistance capacity may be damaged by gale in Taiwan. To improve the structural resistance of the greenhouse to reduce the natural disaster loss. In this study, TAIWAN CPAMI greenhouse structure specifications were included in the analyses of wind-resistant performance of greenhouse. Three improved design models and a control structure was under comparison, the deformation of the control structure was high deformation. Deformations of the three improved type : T-type, Hill-type, and V-Type, V-type obtained the best wind-resistance capacity, The restrain of deformation was 39.3 %. Hill-type obtained the second lowest wind-resistance capacity was 33.4 %. T-type obtained the Lowest wind-resistance capacity was 20.9 %.
