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.
2. See connection figure below. The rivets is 7/8 in. in diameter. According to the rivert supplier,
the allowable stresses for the material are t = 15 ksi and o, = 32 ksi. What is the allowable load of
the connection?
