Abstract :In the study, the weight efficiency of the Triple Friction Pendulum Bearing insert ignore into journalissuearticles values(TFP); Isolators is investigated on optimal weight of planar steel frames. For this investigation, an optimization program based on Artificial Bee Colony insert ignore into journalissuearticles values(ABC); algorithm have been developed for this study. In the design of steel frames, the structure should satisfy strength, inter-story drift, top-story drift and geometric requirements that are implemented from LRFD-AISC. For the research, 8 different planar frames were optimized as seismic-isolated and fixed-based, which were diversified according to story height and bracing. According to the results, the frames with TFP isolators, especially non-braced ones are a lot more advantageous regarding the optimal weight.
