Filler metals for the welding of beams, columns, and plates in the SidePlate connection shall meet the requirements for seismic force-resisting system welds in the AISCSismic Provisions.
User Note: Mechanical properties for filler metals for seismic force-resisting system welds are detailed in AWS D1.8/D1.8M as referenced in the AISC Seismic Provisions.
The following welds are considered demand critical welds:
-
(1) Shop fillet weld {2} that connects the inside face of the side plates to the wide-flange or HSS columns (see plan views in Figures 11.14, 11.15, and 11.16) and for biaxial cruciform dual-strong axis configurations connects the outside face of the secondary side plates to the outside face of primary side plates (see Figure 11.5).
-
(2) Shop fillet weld {5} that connects the edge of the beam flange to the beam flange cover plate or angles (see Figures 11.17 and 11.18).
-
(3) Shop fillet weld {5a} that connects the outside face of the beam flange to the beam flange U-shaped cover plate or angles (see Figures 11.17 and 11.18).
-
(4) Field fillet weld {7} that connects the beam flange cover plates to the side plates [see Figure 11.19(a)] or connects the HSS beam flange to the side plates.
-
(5) Fillet weld {8} that connects the top angles to the side plates in the field-bolted connection.
-
(6) Shop weld {9} that connects side plate {A} to the column face (see Figures 11.20 and 11.21).
-
(7) Shop fillet weld {10} that connects the intersecting orthogonal side plates to construct the side plate interlock assembly in biaxial connections (see Figures 11.20 and 11.21).
