Article Citation :Anisrosyidah ,Fauzrifahimuddin ,Rahmawatiayudia , (2016 ) " The Development Length Of Steel Bars For Precast Concrete Connection Using Grouting " , International Journal of Mechanical and Production Engineering (IJMPE) , pp. 19-22, Volume-4,Issue-2

Abstract : The connection of precast concrete with steel bar can be strong if there is no slip between each other. Need a good development length and grouting to improve bond strength between concrete and steel bar. The slip behavior can be obtained with experimental testing in laboratory or making simulation modeling using software. This paper conducted by software simulation approach to compare the laboratory experiment. The methods of research are divided in two steps, first step is to find out the bond strength between concrete and steel bar using Masterflow 810 grout and the second step to find out the failure pattern of specimens. The result is the bond strength of the specimen models using Masterflow 810 was 6,292 MPaand the bond strength of the specimen models without Masterflow 810 was 6,223 MPa. The result of the development length of the specimen models using Masterflow 810 was 193,434 mm and the development length of the specimen models without Masterflow 810 was 194,662 mm. Average development length of first step result was 200 mm (ld). The failure pattern of three models variation, less than ld (120 mm and 160 mm), equal to ld (200 mm), and more than ld (260 mm). The result of the failure pattern is the steel bar reach yield condition. There were two types failure, they are: yielding and broken at steel bar. The results of specimen models output were well matched with the experimental investigation. The greater the development length, the better the bond strength will be. Keyword—Bond Strength, Development Length, Precast Concrete Connection, and Steel Bars.
