空氣動力理論的推進及工程計算能力的進步，使得國內的橋梁工程不斷地突破求新，再加上為配合橋梁外觀的美學，及世界潮流的環保概念，於是懸吊橋與斜張橋的跨徑也陸續的增加，因此橋梁斷面的設計趨於細長化發展，亦即橋梁斷面需使用較輕的材質且強度較佳的材料，因此採用輕薄流線的橋梁斷面才是時勢所趨。因長跨徑的橋梁具有較大的柔度，所以其受風力而引發的不穩定現象的機率也大增，伴隨衍生的問題，首重於橋梁的受風反應現象。而一般橋梁風洞實驗分為兩種:(1)斷面模型實驗、(2)全模型實驗，本論文以此兩大實驗為主軸，建構並設計氣動力資料庫提供知識分享的平台。 利用PHP與SQL作為系統的基礎，採用橋梁風洞實驗為核心知識的方式去建置資料庫應用系統，應用資料庫擁有的資料，經由資料擷取和篩選過濾的過程，將查詢出的結果輸出表格化、圖型化，讓使用者能分享到橋梁風洞實驗多樣的研究成果。 The advances of aerodynamic theory and engineering computing keep making breakthroughs and technical innovations in domestic bridge engineering. Moreover, the considerations of bridge esthetics and environmental issues also push for the main spans of cable-stayed and suspension bridges to become longer and longer. The section design of bridges progresses toward long and thin, which draws the need for lighter and better strength material. While the spans of bridges getting longer, the structural rigidity of bridges usually reduces. For these reasons wind-induced instability becomes an important issuefor large-span bridges with high structural flexibilities. General bridge wind-tunnel test can be classified into two types: section model test and full model test. The study based on these two kinds of tests to design and implement a bridge aerodynamic database providing a platform to store and share experimental data. The implementation of the system was based on PHP and SQL. The kernel knowledge that used to development the database management system was from bridge wind tunnel tests. Through data queries and filtering, various results of bridge wind tunnel tests in the database can be shared in the forms of tables and figures. Because of the large amount of data involved, it needs effective data management means to add, modify and delete data in the database. Following the line of reasoning, this thesis developed a web-based data management system to display and share the variety of bridge experimental results.
