Another example is a three-sided beam-to-column connection comprising three column flanges. Another function of the beam-column joint is to help the structure to dissipate seismic forces so that it can behave in a ductile manner. Beam-column joint must transfer the forces, such as moment, shear and torsion, transferred by the beam to the column so that the structure can maintain its integrity to carry loads for which it is designed. For moment connections, bending, tension and compression forces are the driving factors behind the design. The connection specimens consist of a W21 beam member with a 1" thick welded end-plate and a W14 column member which is stiffened by a 1/2" column stiffener (continuity plate) that extends either full-depth of half-depth across the column web.
