Abstract:
In evaluating the damage observed in the structures can be seen that the beam to the wall connection in the walls with openings has severe damage and repair and reconstruction of the beams at the connection is very expensive and difficult. One way to improve seismic behavior and reduce damage in the beams are using steel fibers. Hence in the present study the effect of different fibers in seismic behavior of coupling beams with different length to depth ratio are investigated. The concrete used in the beams of high strength concrete (C60). Therefore, nine model with length to depth ratio of 1.75, 2.25 and 2.75 first without fiber and then with 1.5 and 3 percent made in ABAQUS software. This model are placed under the cyclic load. The purpose of selecting this length to depth ratio is to evaluate the effect of fibers in the deep and shallow beams. The results of the analysis of different models indicate that the use of steel fibers improves the shear capacity, flexural capacity and ability to absorb energy and the impact of fibers in the deep beam is more than in shallow beam
