A lot of efforts have been made in the last years in order to set up a valid methodology for the design Reduced Beam Section (RBS) connection. The research activity has been devoted both to analytical and to the experimental aspect. In particular, different experimental tests showed that RBS connections designed according to the most modern seismic codes are able to safeguard the connection due to the yielding of the adjacent RBS. But in all the past researches and experimental tests the role that vertical loads can play was neglected or not properly accounted for. This study proposes a new procedure for accurately computing the relation between RBS location, vertical load and amount of section reduction for ensuring that the yielding of beam-column connections is always avoided. This goal can be realized by requiring that plasticization occur in the reduced sections or in a reduced section and in an intermediate section of the beam.

Abstract
A lot of efforts have been made in the last years in order to set up a valid methodology for the design Reduced Beam Section (RBS) connection. The research activity has been devoted both to analytical and to the experimental aspect. In particular, different experimental tests showed that RBS connections designed according to the most modern seismic codes are able to safeguard the connection due to the yielding of the adjacent RBS. But in all the past researches and experimental tests the role that vertical loads can play was neglected or not properly accounted for. This study proposes a new procedure for accurately computing the relation between RBS location, vertical load and amount of section reduction for ensuring that the yielding of beam-column connections is always avoided. This goal can be realized by requiring that plasticization occur in the reduced sections or in a reduced section and in an intermediate section of the beam.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
