IFC建築資訊內容應用於結構分析資料擷取

Abstract

IFC是一種開放性資料格式作為資訊的交換以及共享使用於整個營建管理上，採用BIM(Building Information Model)、物件導向等技術，進行資料內容的處理，避免資料傳遞時發生錯漏造成財務和時間上得損失。 本研究的目的為了解IFC資料結構內容，由於IFC資料能用於營造業各生命週期，故冀望於結構分析時，能提供所需求的資料，做為銜接建築與結構分析資訊的傳遞，因IFC資料內容繁雜，本研究針對結構分析所需資料進行擷取，並建立結構分析部分資訊，以節省在結構分析時重複建置模型資訊的時間提高效率。 研究中因結構分析所需求之部分，需抽取IFC資料內容中的結構構件梁、柱位置、長度、斷面及材料資訊。所使用程式為 “JAVA”語言撰寫，推導增加斷面性質、材料參數、節點資訊等，用以結構分析模型建置使用且補充IFC資訊建構不足部份。

IFC is an open information model used to exchange and sharing information for buildings. Via BIM (Building Information Model) concept and OO(Object-Oriented) carry on the data information process to avoid cost and time loss. It use clear text format to store data. Which is easy to accept from computer aided applications. It intends to represent most of the necessary building data through its lifecycle. The purpose of this research is to understand the contents of IFC. Although IFC is arranged to be used in building industry each life cycle phase, some efforts still need to be made within different phases. In this research, data collection from IFC file is proceeded to obtain data for structural analysis. Such information as structure beam and column, position, length, section and material information need to be collected to perform sectional, material, joints and member data. JAVA programming language is utilized to achieve this goal.
