Experiments on External Column Connections in Composite Frames.

摘要

Tests are described on ten specimens representative of beam-to-column connections at exterior columns of rigid frames. Three of the specimens are of bare steel and seven of composite construction. The columns are all of I-section bent about the major axis,and are encased in plain concrete to a minimum cover of 50mm. The composite beams are of T-section and the shear connection is made with welded studs. The steel core components are attached using typical welded connections. It is shown that composite action can be realized in the beam at the face of the column,and assessment has been made of the contribution of the column casing to the rigidity of the connection.
