Computer Program for Reinforced Concrete Bar Bending Schedulling to Increase Efficiency of Reinforcement

Abstract

The construction project consists of several components, one of them is a reinforced concrete. Reinforced concrete construction contributes to 30% of the total budget or 80% of the total civil work. Meanwhile, judging from the proportion provided by the use of steel reinforcement reaches 45% of the contribution of the use of reinforced concrete. The use of steel reinforcement that is not planned well lead to cost overruns and the resulting increase in waste production. The waste is unlikely to be used again because the length does not qualify the existing needs. In terms of environmentally wasteful use of steel reinforcement is not aligned with the slogan green construction. According to the Environmental Product Declaration (EPD) in 2012 the production of steel reinforcement produces CO2 gas 430 kg CO2 eq /ton. On the other hand, local contractors in Surakarta never planning the use of steel reinforcement. Contractors plans and cuts of reinforcement. It increase potential construction waste due to inaccurate planning. Therefore in this study are create a computer program to design a model of bending reinforcing steel. Finally, steel reinforcement planning are better obtained. This program is applied to create a Visual Programming software, ACAD, Crystal Report, and Microsoft Database. Visual Programming is used as a place store of scripts and programs to connect database and Crystal Report. Microsoft database used to store data and Crystal Report are employed to display the results of the program. Furthermore, scheduling program of bar bender can be created. the time of production of reinforcement detailed is faster. By inputing a cross-section measurements and information reinforcement used various bending of reinforcement pieces are produced automatically. Crystal Report output can be made a flexible and attractive form to look at as well as the ability to transfer to other programs such as MS Word, Excel and PDF. Output can display different forms of reinforcement pieces with illustrated picture and the required amount of steel reinforcement in accordance with the dimensions and types.
