Abstract
An improvement on the end plate shear connection (Table IX, Section 4-57, Seventh Edition A I S C Manual of Steel Construction) in which the end plate has an integral stem plate at right angles to the end plate and offset from the center line of the end plate to compensate for the web thickness of the beam to which the end plate is to be connected. The end plate is secured to the web of the beam by a shop weld with the weld adjacent the end plate fully penetrating the web, the stem plate and the end plate. Before welding, the stem plate is clamped to the web and minor adjustments made so that when welded the finished length of the beam will be proper and the end plate will be properly located and aligned with the center line of the beam. The end plate - stem plate unit is prefabricated in stock sizes. The unit may be a rolled shape. The stem plate may be joined to the end plate by a single fillet weld at the junction between the stem plate and the end plate remote from the web. The stem plate serves as a back-up bar while making a full penetration weld between the end plate and the web, from one side only of the beam.
