SITUATION A: A tension member consisting of two channels and two plates PL 13mm x 280mm arranged as shown to support the service loads, Pees lad = 900KN and Pwe tad = 1400KN. The member is assumed to be 9 meters long and is to have four lines of 22mm diameter bolts. Use standard sizes for the PL 13x280 C10 hole diameter. All steel will be A36 steel and neglect block shear. Assume U=0.85. Select the lightest C10 channels and determine its tensile capacity. Use ASD (AISC) specifications. Write your final answer on the space provided. Determine the following. PL 13x280 50 180 50 1. The required gross area from yielding of the gross section 2. Assuming a shear lag factor of 0.85, determine the required net area from fracture of the net section 3. Determine the minimum radius of gyration on the given built up section. 4. Determine the slenderness ratio of the given built up section. 5. Determine the lightest C10 shape for the limit state of yielding and tensile rupture, and slendemess ratio. 6. Determine the tensile capacity of the given built up section. Use U = 0.85.
