Effect of U-Shape Thickness on Upgrading Capacity Momen of Precast Beam Column Joint Using CFRPS

Research to investigate the possibility of CFRPS to be a connecting material of beam column joint had been presented [1]. This paper present the effect of U-shape thickness to upgrade the capacity momen of joint. Three specimens were prepared and tested so far. One of them was monolith connection that used as a control specimen (MN). The others were C1S1, joint with one layer of U-shape using one belt and C2S1, joint with two layer of U-shape using one belt. Performance of the three specimens are present in this paper. Results indicated that upgrading twice of CFRPs thickness had increased 2.1 times the momen capacity of joint. The C1S1 reached 15 kN, just 62.5 % of capacity momen respectively to the control specimen, but the C2S1 was 31.5 kN, 131.3 %. . s Beam-column joint, U-shape, U-shape thickness, belt, CFRPs, capacity momen
