Experimental study of seismic response of different structural systems

摘要

During an earthquake a large amount of energy is released and structures are impacted by these forces. In order to reduce the response of a structure undergoing vibration it is necessary for the structure to absorb or dissipate the energy. There are two methods to improve seismic protection of a structure, either by increasing its stiffness (e.g. shear walls, bracings, MR-Frames dual systems) or by using modern methods to increase the performance of the structure (i.e. passive, active, semi-active, and hybrid control systems). This paper presents an experimental study of the dynamic responses of a shear wall model, viscoelastic damper model and bare frame model under different seismic excitations. Damping, stiffness, acceleration, velocity, and story displacement are calculated and compared for different indicative models. The results are presented and conclusions drawn on the basis of the study.
