This is the report of the experiment on full-scale beam-to-column connections. The furpose of this experiment are 1) to investigate the effect of horizontal stiffeners of beam-to-column connection in steel frame, which work very effectively in the case of bare steel structures, 2) to examine the deformation capacity of the connection in the plastic range, which is very important in case of plastic design or dynamic analysis of structures. Therefore we performed this experiment, using two specimens. One is with stiffners and the other is without stiffeners. The resnlts are summarized as follows. 1. The horizontal stiffeners in steel frame have no inflnence upon the strength and the rigidity of the steel-reinforced concrete beam-to-column connection, if the concreta is well filled up. 2. These specimens have good ductility. The ultimate ductility factor (which means the ratio of ultimate deflection of the structure to that of elastic limit.) are 8.1 (with sliffeners) and 7.7 (without stiffeners).
