AbstractDemand of precast concrete in the building construction is increasing because the precast concrete is faster in construction and higher quality control compared to the site-cast concrete. The weight of precast concrete sometimes must be under consideration due to the reasoning of the erection precast concrete element into the building construction. If the span of reinforced concrete beam is quite long, therefore the beam needs to be divided into two or more segments so that the segment can be easily carried and put in the building construction. This experimental program to study about the capacity of reinforced concrete beam to beam connection. Three beams were cast and tested under monotonic loading. The first beam was the beam without any connection as a reference beam. The second beam had a connection in the middle span using steel plate in top and bottom of beam. While the third beam had a connection in middle span with a connection was using the steel plate which was fully covering the connection. All the beams’ dimensions were (150 mm × 250 mm) and span of the beam is 3000 mm. Four longitudinal bars 10 mm in diameter were used to be tension reinforcements and two longitudinal bars having 10 mm of diameter to be compression reinforcements. Reinforcements with diameter of 8 mm were used as stirrups. The results of the study show that the capacity of load-carrying of the beam with the connection of the steel plate in top and bottom connection (BC-1 beam) was lower compared to the reference beam (BN beam) and BC-2 beam. While the beam with the connection fully covering with the steel plates (BC-2 beam) showed had higher load-carrying capacity and more ductile than the reference beam (BN beam) and BC-1 beam.
