Figures 11.14 through 11.16 show typical one- and two-sided moment connection details used for shop fabrication of the column with fillet welds. Tests have shown that the horizontal shear plate {D} need not be welded to the column flanges for successful performance of the connection. However, if there are orthogonal forces being transferred through the connection from collector, chord, or cantilever beams, then fillet welds connecting the horizontal shear plates {D} and the column flanges may be required.
In the field-welded connection, tests have shown that the use of oversized bolt holes in the side plates {A}, located near their free end (see Figure C-11.3), does not affect the performance of the connection because beam moments and shears are transferred through fillet welds. Bolts from the side plate {A} to the vertical shear element are only required for erection of the full-length beam assembly prior to field welding of the connection and may be removed, at the contractor’s discretion after the field fillet welds have been applied (also implying that if all the erection bolts cannot be placed, it is acceptable as it relates to the performance of the connection).
Figures 11.17 and 11.18 show the typical full-length beam detail used for shop fabrication of the beam with fillet welds. Multiple options can be used to create the vertical shear element (if needed), such as a combination of angles and plates or simply bent plates.
Figures 11.19(a) and 11.19(b) show the typical full-length beam-to-side plate {A} detail used for field erection of the beam with fillet welds and bolts, respectively. In the field-bolted connection, either longitudinal angles {G} (rolled or built-up) or horizontal plates {T} that are welded to the side plates {A} may be used to transfer the load from the beam to the side plates {A}, as shown in Figure 11.19(b).
Figures 11.20 and 11.21 show shop weld {9} connecting side plate {A} to column face as well as shop weld {10} that connects the intersecting orthogonal side plates to construct the side plate interlock assembly in biaxial connections.
