Fragile behavior in the area around the connections which is tangent on beam to column and also incidence of brittle cracks and failures in this area, in the event of severe ground shaking, are the main problems and disadvantages that have negative effect on the performance of steel bending frames and would have restrictions effect on the of the frame's plasticity behavior. To solve the problem of bending the frame, two methods have been proposed. In the first method, the connection will be strengthened so that has enough resistance and sufficient strength to prevent cracks and failures to non-elastic deformation of the frame in the inner part of beams be answered. In the second method,...
