摘要: 本論文嘗試將整個房屋結構初步設計的流程自動化。首先由結構技師將欲分析之房屋結構物藍圖上傳至本研究之房屋結構設計平台,然後將會剖析此工程圖檔,擷取出所需要之工程資訊(本研究之系統僅能剖析矩形平面柱線圖),並存入資料庫中。接著透過Unsupervised Fuzzy Neural (UFN)的輔助設計,在初步設計時,可以透過案例假設此結構物桿件的斷面尺寸。最後當房屋結構物設計完成後,平台會產生與實體結構物比例相同的虛擬實境3D結構物模型,也就是此結構物之VRML視覺化查詢介面,透過此介面可以查詢此房屋結構物之相關工程資訊。 整個系統的雛形是以全球資訊網(WWW)的三層架構網站(3-Tier Web)來建構房屋結構設計平台,並以LAMP(Linux、Apache、MySQL 、PHP)為軟體環境架構;其中以C語言撰寫型鋼資料庫之轉檔機制(轉成VRML檔案);再以VRML建置3D的視覺化查詢介面。研究成果將可提供營建相關從業人員一個視覺化(Visualized)及網站化(Web-Based)的房屋結構設計平台。
The thesis tries to automate the process of the building structure design in Civil Engineering. First , a structure engineer uploads the blueprint of the building to the building structure design platform. The platform derives the engineering information from the blueprint and stores the associated engineering information to the database. In this work, the uploaded blueprint is limited to the rectangle plane building structure. Then, Unsupervised Fuzzy Neural(UFN)is employed to determine the cross-section size of the elements in the building. Finally, when the building structure design is finished, the platform will produce a virtual 3D building model which is proportioned to the real building. The model is also viewed as the visualized interface that is used to look up the engineering information of the building. The platform of this research is established on a 3-Tier World Wide Web(WWW) and the software environment is constituted through Linux , Apache , MySQL , and PHP. The mechanism which transforms the formed steel database into the VRML files is implemented by C program language. Finally , the visualized interface of the building is established via VRML. The proposed model of the research provides constructer a visualized and web-based building structure design platform.
