The tension connection shown below is comprised of a 4x10 and two 2x10 DF-L No. 2 members. The controlling ASD load combination is D + L where L is from occupancy. The connection is at normal temperature and wet in-service conditions. Assume there are two rows of 1/2 inch bolts and that all spacing and edge distance requirements will be met so that C₁=1.0. P./2 P./2 2 rows of 1/2 inch bolts (3 bolts/row shown, but could be more) 2x10 2x10 4x10 2x10 4x10 2x10 1. Find the maximum load, P, the tension connection can resist based on tension failure of the 4x10. Use the net area of the 4x10 for your tension strength calculation. 2. Find the maximum load, Pa, the tension connection can resist based on tension failure of the 2x10s. Each 2x10 will take half the load, i.e., each 2x10 resists Pa/2 Use the net area of the 2x10s for your tension strength calculation. 3. Determine the minimum number of bolts per row so that member failure controls over failure of the connection. Assume the group action factor is 0.9 4. Based on your number of bolts per row, compute the actual group action factor. For all problems, clearly explain your work and draw supporting figures.
