本研究主要建立一套包含前處理、分析引擎與後處理功能的圖形 使用者介面軟體,可以讓使用者簡單與效率地操作介面平台,使用三 維結構與固體動力分析程式,探討橋梁之耐震性能。在圖形使用者介 面中,使用者參照視窗的文字提示與彈出式對話框的訊息,建立分析 所需之輸入檔,再進行分析程序,在圖形使用者介面的輔助下,能夠 節省大量建立輸入資料所需的時間,且可以有效降低輸入文字檔格式 錯誤的可能性。完成程式分析之數據,可藉由介面提供之繪圖函式庫, 將輸出數據圖像化,並且透過介面提供使用者基本操作功能。圖形使 用者介面開發過程全程使用物件導向程式語言Python 來設計前處理 與後處理,並聯結分析引擎,完成一連貫的圖形使用者介面工作平台。;The research is aimed to develop a graphical user interface program to integrate system. The program includes preprocessing, analysis procedure and post-processing for 3D dynamic analysis of structure and solids, which makes user can design model of structures in an efficiently and intuitively way to discuss the nonlinear behavior of bridges subjected to extreme earthquakes. In the interface, user just needs to follow the guide in the windows and the information of pop-up dialog to finish building input data file. With the help from the interface, it can save a lot of time and greatly declined the format error in building input data file. After analysis finished, the interface offers user plot library which makes output data visualized. And though the interface, user can also manipulate the figure. This research use Python which is an object-oriented programming language with many standard libraries to develop a complete graphical user interface work platform connecting with 3D dynamic analysis of structures and solids.
