About this detail

This seismic drag connection detail joins steel beams to a column centerline using high-strength A325 slip-critical bolts and a full-height stiffener connection plate sized per the accompanying schedule. The beam web receives a fillet weld sized per the table values, with specific requirements when the fillet size exceeds the beam web thickness. Bolt counts range from six 7/8-inch diameter bolts for W12 and W14 beams up to sixteen 1-inch diameter bolts for W30 beams, utilizing a 1/2-inch thick connection plate. Spacing is detailed with a 1-inch maximum clearance from the column flange, 3-inch typical vertical spacing, and 4-inch and 2-inch horizontal edge distances.
