In this study the column being modeled is the lowest column, the bottom of which is pinched and the other end free, by adding fiber to the concrete mix mixture. The addition of fiber as much as 1% -3% of heavy cement. The fiber used consists of a fiber tie wire with a diameter of 1 mm, a length of 60 mm and the two ends are bent. While the steel used in this study was 112,903 mm in diameter, 1,450 mm thick and 700 mm long.The results of the study are a strong test of the composite column pressure on the eccentric and centric loads ie on specimens without fiber material producing average moments and average maximum loads (14720,56250. 103 Nmm and 532,50.103 N), for fiber reserves 1 % (15535,625,103 Nmm and 557.5,103 N), for 2% fiber content (15647,675,103 Nmm and 625,103 N), for 3% fiber content (18235,00,103 Nmm and 650,00,103 N). It turns out that the results of this study indicate that the addition of fiber to the concrete mix increases the strong capacity for centric loading or eccentric loading.
