Tests of Welded Steel Beam-To-Column Moment Connections,

摘要

A test program was recently completed which had as its objective the investigation of various symmetrically-loaded moment-resisting beam-to-column connections which are of extreme importance in design and construction of steel multi-story frames. This report discusses the results of three specimens included in the overall twelve-specimen program. The three connections presented are: (a) a fully-welded connection where the beam flanges and web are groove welded to the column flange (b) a seated connection where the column flanges again are groove welded to the column flange but beam shear is carried by a beam seat which is fillet welded to the column flange,and (c) a connection in which only the flanges of the beam are groove welded to the column flange,leaving the beam flanges to carry both shear and moment. All three connections were fabricated of the same size beams and columns.
