The paper presents the experimental investigation of an eccentric steel structure under seismic loading at varying height and varying mass conditions on a shaking table. In order to test dynamic responses of a steel structure the ground and a four-storied eccentric steel structure were prepared and a dynamic analysis test was conducted. The seismic data from accelerometers attached to each story of a steel structure were recorded like acceleration, displacement, velocity, etc. According to the correlation of acceleration, displacement, velocity other seismic properties like story drift, drift ratio, inertia forces were predicted. The prototype model showed irregularities and eccentric effects on various seismic parameters. The eccentric steel model on the shaking table is a useful tool for teaching and well shows the effects of the earthquake on a structure.
