title = "Evaluation of available force reduction factors for concrete bridges",
abstract = "The paper presents a methodology for evaluating available force reduction factors (R) for seismic design of concrete bridges. The usual procedure for analytically estimating this factor is through pushover curves derived for the bridge in (at least) its longitudinal and transverse direction. The shape of such curves depends on the seismic energy dissipation mechanism of the bridge; hence, bridges are assigned to two categories, those with inelastically responding piers and those with bearings and strong, elastically responding, piers. The methodology was applied for evaluating the available R-factors (for bridges of the first category) or R eq-factors (for bridges of the second category) of seven actual bridges, forming part of Egnatia Highway, in Greece. It was found that in all cases the available force reduction factors were higher than those used for design.",
