DUCTILITY OF THE PRECAST AND MONOLITH CONCRETE ON BEAM-COLUMN JOINTS UNDER CYCLIC LOADING

The use of precast construction in recent years is increasing rapidly, and therefore has several advantages over conventional constructs which can provide high quality control, efficient in manufacturing of constmction, can save time and costs and can reduce constmction waste resulting from the use of formwork. One important part of the work is the work on the constmction of precast beam-column connections, connection areas need to be designed such that it can meet the criteria of strength and ductility of the main building in case of earthquake loads. This study is an experimental study to investigate the ductility of precast concrete compared to monolith constmction on the beam-column joints structure subjected to cyclic loading. Test specimen consists of 2 beam-column joints, 1 precast constmction (PC) and 1 monolith constmction (MC) is made with a full-scale 1:1. Column dimensions are 300 x 300 x 2600 mm and beam 200 x 250 x 1500 mm. connecting the precast concrete is a straight model, spliced using cement grout. Testing was conducted using displacement control, with the gradual type. The study reveals that PC has higher ductility compared with MC. Ductility of PC, mu = 4,379, while the MC, mu = 2,333.
