Precast Concrete Column Beam Connection Using Dowels Due to Cyclic Load

The beam-column connection plays an important role in the building structure, especially when the load is cyclic. The main problem that must be solved is the beam and column connection panels. The purpose of this study was to analyze the characteristics of the hysteresis loop of the displacement load relationship with the control displacement of the precast beam-column connection due to cyclic loading. The research method used is the experimental method with a measurable object design test and a special testing method. The results of this study indicate that normal concrete has a compressive strength of ۲۶.۴۳ MPa, while grouted concrete has a compressive strength of ۳۶.۹۷ MPa. The findings of this study also show that the bond stress grouted concrete increases by ۱۰۲.۴% from normal concrete for D۱۳ diameter screw reinforcement, while for D۱۶ diameter, the adhesive stress increases by ۵۱.۶۳%. The findings of this study also show that in the ultimate condition, the load obtained in the tensile load is ۱۳.۵۸ kN with a displacement of ۸۷.۵۸ mm, while the compressive load is ۱۲.۶۲ kN with a displacement of ۸۸.۳۰ mm. This study concludes that the behavior of precast beam-column joints with dowels is stronger in resisting cyclic loads.
