Past research has unveiled the vulnerability of this type of system to earthquakes. Especially problematic are the exterior wide beam-column connections. This paper presents preliminary experimental results of a bigger research project aimed at evaluating the vulnerability of the RCMRF with wide beam-column connections built in Spain during the 1970s, 1980s and 1990s, and to develop innovative seismic upgrading strategies based on the use of hysteretic energy dissipators. To this end, two 3/5 scale test models representative of exterior subassemblages in a prototype six-story building were subjected to gravity-load levels typical of those acting during an earthquake, and quasi-static cyclic lateral loads until failure. The specimens exhibited a “strong column-weak beam” type of flexural yielding mechanism. The average drift ratios at first yielding of the wide beam longitudinal reinforcement and at failure were 2.2% and 4.5%, respectively.
