Green frame is column-beam structure composed of precast concrete members. Based on Revision of Structural Concrete Design Code, the bottom rebar of beam shall be extend at least 150mm into the support member. However, if the bottom rebar extend to satisfy Revision of Structural Concrete Design Code, the installation fo beam is impossible due to interference between the columns and beams. Thus, the aim of this study is estimation of production length of precast concrete beam by using splice length of bottom rebar. In this study to solve this problem, lap splice were used on the join. This study was calculated length of the reinforcement by the diameter. According to the length of the rebar, the production length of beam concrete was calculated. The results of this study will satisfy the Revision of Structural Concrete Design Code about column-beam connection when green frame will be applied.

Green Frame is a column-beam structure built by steel frame joints embedded in the columns and beams. Here, the steel frame embedded in the columns and beams is not a standardized product, instead it needs to be order-produced. The quantity for each steel frame size should be calculated to estimate the quantity of steel frames to be manufactured. However, it is highly time-consuming and requires a lot of effort in calculating the quantity of steel frames, for there are a wide range of steel frame types that are embedded in the columns and beams. To solve this problem, the study proposes an algorithm for calculation of the amount of steel frames with ease and promptness. When a program is developed using the algorithm proposed in the study in connection to the information on precast concrete members prepared in the design phase, it is anticipated that the manpower required as well as the manufacturing time will be decreased.
