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.

The rigid frame shown in Figure is unbraced in the plane of the frame. In the direction perpendicular to the frame, the frame is braced at the joints. The connections at these points of bracing are simple (moment-free) connections. Roof girders are W14 x 30, and floor girders are W16 x 36. Member BC is a W10 x 45. Use A992 steel and select a W-shape for AB. Assume that the controlling load combination causes no moment in AB. The service dead load is 25 kips and the service live load is 75 kips. a. Use LRFD. b. Use ASD
Rigid bar ABC is supported by member (1) at B and by a pin connection at C. Member (1) has a cross sectional area of 1.35 in.² and a yield strength of 45 ksi. The pins at B, C, and D each have a diameter of 0.7 in. and an ultimate shear strength of 78 ksi. Each pin connection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.5 with respect to its yield strength. The minimum factor of safety required for pins B, C, and D is 2.9 with respect to the pin ultimate shear strength. Determine the allowable load P that may be applied to the rigid bar at A. Use overall dimensions of a = 46 in. and b = 94 in. D (1) b A kips P Answer: Pallow= i a B
