Use load and resistance factor design and select a W shape with a nominal depth of 10 inches (a W10) to resist a dead load of 175 kips and a live load of 175 kips. The connection will be through the flanges with two lines of 1 1/4–inch-diameter bolts in each flange, as shown. Each line contains more than two bolts. The length of the member is 30 feet. Use A242 steel.
A plate 1⁄2 3 4 of A36 steel is used as a tension member to carry a service dead load of 6 kips and a service live load of 18 kips. It is to be attached to a 3⁄8-inch gusset plate, as shown in Figure. Design a welded connection.
For the clevis connection shown, determine the shear stress in the 20-mm-diameter bolt for an applied load of P = 130 kN.

The connection will be with longitudinal welds. Use an estimated shear lag factor of U = 0.85. (In a practical design, once the member was selected and the connection designed, the value of U would be computed and the member design could be revised if necessary.) The length is 17.5 ft.

The load consists of 15 kips dead load and 45 kips live load. Four 7⁄8-inch-diameter Group A bolts are used. The column is of A992 steel, and the bracket is A36. Assume all spacing and edge-distance requirements are satisfied, including those necessary for the use of the nominal strength in bearing deformation (i.e., 2.4dtFu)*, and determine the adequacy of the bolts for the following types of connections: (a) bearing-type connection with the threads in shear and (b) slip-critical connection with the threads in shear.arrow_forwardDesign a framed beam connection for a W18 x 50 to support a dead load reaction of 30 k and a live load reaction of 20 k, using the LRFD and ASD methods.The beam’s top flange is to be coped for a 2-in depth, and 7/8-in A325-X bolts in standard-size holes are to be used.The beam is connected to a W27 x 146 girder.
