中文摘要 | 直交集成材(Cross Laminated Timber,簡稱CLT)是新興的建築材料,對於其機械性質之準確的評估十分的重要。雖然製作實尺寸的試材進行試驗是了解機械性質最為理想的方式,但所需要的時間及金錢成本相當高昂。相較之下,若利用積層理論於機械性質之評估,可以快速的得到材料製成CLT之機械性質理論值。本研究利用積層理論建立數值模型,模擬不同構成之柳杉CLT的機械性值。模擬結果顯示,不同的集成元厚度對CLT縱向與橫向之壓縮與引張性質並無影響,而增加CLT的層數可以縱向、橫向的機械性質差異。表層使用相同等級的集成元之下,同等級與異等級的CLT機械性質並無顯著差異。 |
英文摘要 | Cross laminated timber (CLT) is a novel construction material, therefore it is of great importance to determine its mechanical property accurately. Although mechanical properties are best determined by constructing and testing full scale specimens, such experiment often requires a lot of space and is costly to conduct. In contrast, mechanical properties can be quickly determined using lamination theory. Mechanical properties of CLT panels with different configuration is determined and analyzed with lamination theory. The experimental results show that the thickness of lamina has no effect on the longitudinal and lateral elastic properties, and that increasing number of ply decreases the orthotropy of CLT. Also, mechanical properties between a homogenous layup and a non-homogenous layup is not significant when the same lamina is placed on the surface. |
