The three-plate moment connection shown below are all shop- welded- to the column and then field bolted to the girder. The beam is a W18 55 that has a factored moment of Ma = 382 kip ft and a factored shear of V. = 65 kip. All plates are A36 steel (E = 36 ksi, Fu = 58 ksi). Plate 2 is connected to the girder using four bolts as shown. All bolts for the connection are 7/8" diameter A325-X. Plate 1 Plate2 2.00" 2.75" W18 55 2.75" 2.75" 2.00" `Plate3 3.00" 2.50" (a) Design Plate 1, including the required number of bolts and dimensions of the plate. Assume an E70XX weld to the column. Consider limit states only for the plate itself. That is, you do not need to consider limit states for the beam or column. (b) For which plate(s) will you need to check the buckling capacity, Plate 1, 2, and'or 3? Explain.

Question
Transcribed Image Text:The three-plate moment connection shown below are all shop- welded- to the column and then field bolted to the girder. The
beam is a W18 55 that has a factored moment of Ma = 382 kip ft and a factored shear of V. = 65 kip. All plates are A36 steel
(E = 36 ksi, Fu = 58 ksi). Plate 2 is connected to the girder using four bolts as shown. All bolts for the connection are 7/8"
diameter A325-X.

(a) Design Plate 1, including the required number of bolts and dimensions of the plate. Assume an E70XX weld to
the column. Consider limit states only for the plate itself. That is, you do not need to consider limit states for the
beam or column.
(b) For which plate(s) will you need to check the buckling capacity, Plate 1, 2, and'or 3? Explain.
