Period Shifting Effect on the Corner Displacement Magnification of One-Storey Asymmetric Systems

This paper gives a new insight into the dynamic behaviour of one-storey eccentric systems, with particular attention devoted to provide a comprehensive physically-based formulation of the maximum corner displacement amplification, which involves three contributions(translational response, torsional response and their combination). It is shown that the largest amplifications, which mainly occur for the class of torsionally-flexible systems, are due to the translational contribution through to the shift in the fundamental period of the eccentric system with respect to the one of the equivalent not-eccentric system. A simplified method for the estimation of the maximum corner displacement based on the physical properties of the system is finally obtained.
