10 mm 20 mm The assembly above is comprised of a 10mm-diameter steel bolt, and a 20mm-diameter, 2mm-thick bronze sleeve. The bolt and sleeve are rigidly connected at each end by a washer. Assume the following properties: Epolt = 29000 ksi x bolt = 6.6-10-6 /°F Vbolt = 0.35 Member BC is made of bronze with the following properties: Esleeve = 15000 ksi Xsleeve 9.80-106 /°F Vsleeve - 0.35 If the assembly is heated up, which of the following statements best describes how the sleeve will be affected? The sleeve will try to expand longitudinally, but will be restricted by the bolt (because the bolt has a lower coefficient of thermal expansion). The sleeve will go into tension and the bolt will go into compression. O The sleeve will try to expand longitudinally, but will be restricted by the bolt (because the bolt has a lower coefficient of thermal expansion). Both members will go into tension. The sleeve will try to expand longitudinally, but will be restricted by the bolt (because the bolt has a lower coefficient of thermal expansion). Both members will go into compression. The sleeve will try to expand longitudinally, but will be restricted by the bolt (because the bolt has a lower coefficient of thermal expansion). The sleeve will go into compression and the bolt will go into tension.

Situation 4: The lap splice shown will develop a full strength as shown in the figure. Using E70 electrodes. The width of the plate is 50 mm and the thickness is 12 mm. Use Fy = 248 MPa T+ T4 O 29 mm O 30 mm 1. Which of the following nearly gives the diameter of the slot weld using the LRFD method. O 27 mm E70 O 28 mm T T

The tension member is a PL 1⁄2 × 6. It is connected to a 3⁄8-inch-thick gusset plate with 7⁄8-inch-diameter bolts. Both components are of A242 steel.   Note: A242 Fu = 70ksi dh = db + 1/16’’ Use: Consider deformation at the bolt hole   what is the:  minimum spacing as per AISC code provisions  maximum spacing as per AISC code provisions minimum edge distance as per AISC code provisions maximum edge distance as per AISC code provisions
