Abstract

Cause of regarding many case was difficulted for adjusting between joint of elements, then this research was described about joint of element precast with L shape. L shape that is mean, joint of element precast have shape such as word of L and easier to adjusting. This research have molded two beam of conventional (K1,K2) and two beam of precast (P1,P2). Purpose of this research was determined of deflection and maximum moment occur at tension maximum. Just for question of this research was about deflection and moment maximum occur at tension maximum if any load were applicated. Result of precast L shape concrete beam P1 and P2 and conventional beam K1 and K2 were strength of flexural beam at ultimate and deflection of beam at ultimate. Strength of flexural conventional beam K1 at ultimate was achieved 11,38 T at deflection 138 mm. Strength of flexural conventional beam K2 at ultimate was achieved 11,25 T at deflection 163,9 mm. Strength of flexural precast beam P1 at ultimate was achieved 11,21 T at deflection 28,44 mm and strength of flexural precast beam P2 at ultimate was achieved 11,76 T at deflection 26,71 mm. Average compressive strength of concrete beam was achieved 311,89 kg/cm2. Average compressive strength of sika grout 215 was achieved 421,33 kg/cm2 at 9 day. Conclusion of this research about joint type L for precast concrete beam is having good performance only less for ductility. Conventional beam K1 and K2 were showed ductility du/dy behavior at least approximately 4,29 different with precast beam P1 and P2 was has less behavior ductility du/dy at least approximately 1,17.
