摘要

為落實本土化農用設施設計目標，本研究從結構安全與經濟探討台灣地區生物生產簡易式設施的合理設計。採用單斜式構造以輕型鋼材進行設計，考慮室內生物生產需求棟高，在1.36至2.50間取四種跨高比，搭配三種主構架間距變化組合成12個模組，以電腦軟體進行安全性與經濟性分析。結果顯示在棟長度以10 m為一單元，室內面積小於33 m2的較小空間需求時，以跨高比1.4以下、主構架間距2m較經濟；而地板面積約33~55 m2範圍內，以主構架間距2.5m較經濟，其經濟跨高比自1.50起可提高至2.50，以有效擴充室內可利用空間體積。可以確認在主構架構件承受12級風力與5級地震力時，各骨架最大應力比愈接近1時，愈能符合經濟設計。

This study discusses the rational design of bio-production buildings in Taiwan. In terms of structure, this study adopts shed roof as building shape and light-gauge steel as material. Four span-height ratios between 1.36 to 2.50 and three main frame space variations are chosen to constitute 12 modules, then computer software is used to analyze safety and economy of each module. The results show that if the building length is an unit in 10m with space requirement under 33m2, it will be more economy when span-height ratio under 1.4 and main frame space under 2m. Furthermore, if the space requirement of the building is between 33 to 55m2, then the most economy way is to keep the frame space in 2.5m that the span-height ratio may raise from 1.50 to 2.50 and the indoor space is increased at the same time. It can find that the stress ratio of every frame member for the economy designs approaches to one at the twelfth wind load and fifth earthquake load.
