The main purpose of the present research is to investigate the behavior of innovative beam-to-column bolted connection of steel rectangular hollow sections – RHS. The typology of the connection was conceived to combine simplicity in fabrication and erection with structural effectiveness. The connection components are two cleat plates butt-welded or inserted through the RHS column, internally connected to the webs of the RHS beam with top and bottom horizontal lines of bolts. In addition, the tested connections were divided
in two concepts concerning the bolts tightening: (i) regular manual tightening and (ii) pre stressed bolts by controlled tightening. The former allows usual non-friction connection and the later permitted to investigate friction-type. The experimental results permitted to identify the connections bending moment-rotation behavior and comparison with usual concepts of rigid, semi-rigid or flexible classification, in order to support structural design procedures.
