中文摘要 | 本研究以設施安全及用材經濟兩設計原則,探討最常用於生物生產用的簡易式隧道型輕構架溫室之結構設計,以建立本土化設施設計用的基本資料。運用模矩及開放建築概念,設計三種不同高跨比、三種構架尺度、三種主構架配置 間距及二種桁條配置間距角等組合成54組構架,在安全承受十二級風力、五級地震力及構造物自重下,運用結構分析電腦程式STADD-Ⅲ模擬計算所需用鋼量。再探討構成室內單位體積空間,構成室內單伅面積、室內高度等所需用鋼量最少的設計模組,並檢核基礎容許支承力及抗拉拔力,以供設計建造之參考。結果得知高跨比1:3,主構架間距1m,桁條配置間距2-度之平均單伅體積用鋼量最低,為2.44kg/□,較高跨比1:2模組減少33%。較高跨比1:4模組減少46%;其創造1□室內空間量之材料平均成本為114.7元/□,較高跨比12之材料成本減少32%,也較高跨比1:4節省54%。設施所構成的室內可用面積所需用鋼量也可以高跨比1:3最經濟。故建欺棟長度以10m為單元時,設施構成室內的空間量在195□至550□間、室內面積在90□至150□間,以高跨比1:3、主構架間距1m、桁條配置間距20度設計最經濟。 |
英文摘要 | The research presents a tunnel type pipe structure designed for bioproduction. Under the principles of safety and economy, the data bases of the design were estimated. The research also illustrates the comparison of 54 modeling structure including 3 different height and span rations, 3 structure scales, 3 frame spacing and 2 truss pitch angles. The computer program STAAD-Ⅲ, with the demanal of 12th degree wind force and 5th degree earth quake force resistance, calculates and estimates way of constructing while checking the fundamental allovable force. The results find theat the minimum material needed is 2.44 kg/□ with height and span ration equals 1:3, frame spacing is 1m, trust allocation pitch is 20 degree. This saves 33%of the material than module with height and span ratio is 1:2 or 47% than it is 1:4. The average cost of the material to create a 1v inner space is NT$114.7/□, while is 32% less than the height and span ration is 1:2, or 54% less than the height and span ratio reaches 1:4. When the height and span ratio is 1:3, the inner area extends to its maximum and the cost is most economical as well. It is recommended that the buildings stays 1- meter long with inner space between 195 to 550 □ and inner area between 90 to 150□. height and span ratio keeps 1:3. main truss spacing is 1 meter and trust allocation inter remains 20 degree. This combination is the most efficient and safe design founded in this study. |
