seismic design concept is getting attention owing to its advantages over the
conventional methodologies. Particularly, the consideration of duration and
frequency content of the earthquake record are chief superiority of the
concept. For this original design procedure, accurate determination of seismic
input energy is crucially important. Because of solving energy balance equation
is a tedious job, the seismic input energy is determined in terms of <i>equivalent velocity </i> in the literature
mostly. However, it was also shown that this relation is valid for only
undamped systems. Therefore, this study aims to provide the nonsteady relation
between seismic input energy and equivalent velocity for damped systems.
Intensive response history analyses were performed by using plenty of earthquake
records those were selected by considering the impulsive characteristics
(ordinary and pulse-like) and shear wave velocity. It was found that the
relation given in the literature for seismic input energy and spectral velocity
relation is not true for damped systems. Dependently, it is proposed a set of
coefficients considering structural damping properties to modify the existing
relation </span> </a> <span style="font-size:9pt;font-family:Cambria, serif;">. </span> <br /> </p>}, number={66}, publisher={Dokuz Eylul University}
