本研究主要開發一套RC房屋結構梁、柱配筋施工圖自動化電腦軟體,將RC房屋建築結構圖之圖面上相關資料如梁、柱構件材料、尺寸及鋼筋配置等結構設計參數,輸入梁、柱構件設計參數圖視窗,以建立梁、柱構件設計資料庫,依據RC結構之材料性質及設計規範建立之基本資料庫,利用Access資料庫系統、VB.NET程式語言及AutoCAD等軟體,可自動建立梁、柱構件電腦資料檔及圖檔,由VB.NET程式語言所開發之程式,可自動產生某一多跨連續梁及多層柱之詳細配筋施工圖及料單。因係依據規範自動計算鋼筋錨碇彎鉤長度、搭接位置與長度,故可精確控制鋼筋用量,並可自動檢核鋼筋間距及保護層厚度,不但有助於施工,而且避免錯誤,以達到高效率省時及省工之自動化要求。為尋找一種最佳主筋搭接型式及最佳訂尺,減少訂尺用量,以達到省料之目的,本文提出一種簡單且規律之裁切方法,以不同長度之整數訂尺,求得最小訂尺用量之情形,並以線性規劃法之數學模式加以印證結果之一致性。
The purpose of this paper is to develop an automation platform particularly emphasizing on the beam/column reinforcements of a continuous beam/column of a RC building, and it can automatically check all the designs to ensure the arrangements of reinforcements comply with the ACI code. The platform can establish the types of location patterns of lap splices (called as lapping patterns) for the longitudinal reinforcements, calculate every reinforcement’s length, arrange same size reinforcements by length in decreasing order, choose proper stock lengths for bar cutting, and finally determine the best lapping pattern with its optimal stock length by the Trial and Error Method or by the Linear Programming Approach, which would yield the most economical way to supply a proper stock length for cutting. Finally the platform can automatically generate the shop drawing and schedule of the reinforcements which might be very useful for a building construction and management.
