This report describes an experimental study of the behavior of a first-floor girder of a three-story steel frame subjected to earthquake loading. The instrumentation was designed to measure the force and deformation time histories of the girder. The following aspects of the dynamic response are discussed: yielding at the girder ends in the inelastic test and the permanent deformation caused by the dead load effect of the concrete blocks; joint rotations; the dynamic moment capacity of the girder; hysteretic behavior; and ductility ratio.
