Abstract:This paper describes an experimental investigation into the behavior of two reinforced concrete cruciform beam-column subassemblages under simulated seismic loadings. The half-scale specimens used modeled a part of a ductile reinforced concrete frame for a 20-story building at the third floor level. Because of the poor bond of the main bars due to instrumentation within the interior joint for one of the specimens, premature anchorage failure was observed. This kind of behavior, which may occur in practice because of poor workmanship, is compared with that for a specimen with beam bars having full anchorage within the joint. For the latter case a comparison between experimental results and analytic predictions is made. By including the beam fixed-end rotations and inelastic behavior of beams along their lengths, good agreement between experimental and analytical results was obtained.
