This paper deals with numerical study of a newly developed seismic load resisting system called “linked column frame (LCF) system” which can be used to dissipate the earthquake energy and aids the structure to quickly revert to the serviceability level Dominant behavior of this system resembles that of the ductile link beam and as the shear fuse, it mitigate structural damages in various seismic events. In order to investigate the structural behavior of this in the event of near and far-filed earthquakes, after validationg the models by means of laboratory models, 3, 6 and 9-storey buildings were deigned making use of performance based design approach and then, the earthquake-induced responses were investigated by applying near and far-field earthquake records. Based on the results derived from the nonlinear dynamic analysis, the maximum inter - storey drift developed by the near and far-field earthquakes are equal to 3.91, 1.08, 1.65% and 1.74, 3.91 and 4.06, respectively. These values are related to the lower half of the building’s height and in compliance with the comparison between maximum displacement and inter-storey drifts obtained by the method proposed by Shoeibi and Malakoutian et al; the structure takes advantage of the controlled maximum and inter-storey drifts.
