| Abstract: | In order to reveal the dynamic characteristics of the uniaxial-eccentricity base-isolated structure and establish corresponding simplified method of theoretical analysis,a 3-story 2-span base-isolated steel frame model is investigated by means of the shaking-table tests under different eccentric conditions.Then,the relationship between the torsional effect of the structure and the eccentric condition is discussed.Meanwhile,at different eccentricities,not only the change laws of the shear force,torque and ro... |
