Effect of Seismic Isolation with Triple Friction Pendulum Isolator Device on Weight Optimization of Steel Plane Frames

Abstract

In the study, the weight efficiency of the Triple Friction Pendulum Bearing (TFP) Isolators is investigated on optimal weight of planar steel frames. For this investigation, an optimization program based on Artificial Bee Colony (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.
