QUESTION 6
3. check the capacity of the shear connection.
A992: Fy=50ksi, Fu=65ksi
A36: Fy=36ksi, Fu=58ksi
effective bolt hole diameter = bolt hole + 1/16"
beam properties: tw=0.295 in.
Fexx=70ksi
what is the bearing capacity of the shear plate in kips? (2 decimal
places)
A double-angle shape is shown in the figure. The steel is A36, and the holes are for 1/2-inch-diameter bolts.
Assume the Ae = 0.75An.

d. 43.9
For the two lines of bolt holes shown in Fig. 3.6, determine the pitch that will give a net area DEFG equal to the one along ABC. The problem may also be stated as follows: Determine the pitch that will give a net area equal to the gross area less one bolt hole. The holes are punched for 3/4-in bolts.
