THE STUDY OF BEAM CONNECTION WITH DIAGONAL MODELS

The Technology of precast concrete growing rapidly. The concrere research has been aimed to create an innovation simplify and to reduce weaknesses of concrete include precast concrete. This study aims to research the connection of precast beams with combination notches type. This study used precast beams which dimensions were 20x30x270 cm, f'(c) was 25MPa. The precast beams which connection by diagonal types, the length of connection was 15 cm and 20 cm. The samples used 3(three) beams ie. 2 (two) of beams precast as BM-15 and BM-20 which are connected by diagonal types with grouting 0MPa and 1 (one) of monolith beam as BN. The results of researches that the strongest beam precast was BM-20 on 44,05 kN or 30,41 % than monolith beam (BN).
