摘要

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.
