A tension connection consists of A36 steel double angles (two L4x4x1/4 shapes, or 2L4x4x1/4)
fastened to a 4x10 No. 2 Red Oak member with a single row of four 0.875 inch A307 bolts.
The connection is subjected to normal temperatures but wet in-service conditions. Assume
the group action factor is C,=0.95 and the geometry factor is Ca=1. The controlling ASD
load combination is D+ L where L is from occupancy.

Considering the following steel connection. The plates in Pink are 9mm steel plates. The middle plate (Yellow) is
18mm thick. The width of the plate is 100mm. The maximum allowable tension stresses on any of the plates is
100Mpa in Gross Area Yielding and 150 Mpa for Net Area or Tension Rupture. The bolts used are 8mm in
diameter, the holes are 10mm in diameter, no need to add 1.6mm. The bolts allow a maximum of 280 Mpa of
shear. Determine the maximum allowable "P" of the connection in kN.
