This structural detail and schedule specifies skewed bolted beam connections for wide flange beam sizes ranging from W8 to W30. The assembly includes a connection plate welded or attached to a girder web or column flange, with the skewed beam web bolted to the connection plate using three-quarter-inch diameter A325N bolts in standard and horizontal short slotted holes. Design capacities range from 8.2k to 66.3k in single shear based on AISC 9th edition tables for skewed angles between thirty and sixty degrees. Minimum plate thicknesses vary from three-eighths to one-half inch depending on the beam size. General notes require standard bolt holes per AISC and reference standard connection schedules for skewed angles less than thirty degrees.
