Select a pair of C10 channels for a tension member subjected to a dead load of 120 kips and a live load of275 kips. The channels are placed back to back and connected to a ¾-in gusset plate by 7/8-in Ø bolts.Assume A588 Grade 50 steel for the channels and assume the gusset plate is sufficient. The member is25 ft long. The bolts are arranged in two lines parallel to the length of the member. There are two bolts ineach line 4 in on center
Two steel plate tension members have been connected using 0.72 inch diameter bolts arranged in an equally-spaced 9 by 3 rectangular formation. Both plates have a thickness equal to 1/3 in. Take shear fracture stress as 51.2 ksi, clear distance for each edge bolt as 0.12 in, and the clear distance for the other bolts as 1.072 in.
a)Sketch the connection showing all the details and measurements with units.
b)Find the maximum allowable service dead load and live load assuming live load is half as much as dead load. Consider ASD.
A bracket must support the service loads shown in the figure below. The loads act through the center of gravity of the connection. The connection to the column flange is with eight 7/8-inch diameter, A325N bolts. A992 steel is used for all components. Is the connection adequate? Use LRFD. Show all work to verify the bearing strength and the combined effects from tension and shear in the bolts. Ignore any potential prying action created in the WT.
