A plate with width of 400mm and thickness of 12mm is to be connected as shown in the figure. The holes are 2mm larger than the bolt diameter. The plate is A36 steel. Bolt diameter is equal to 34mm. It is required to determine the value of “b” so that the net width along bolts 1-2-3-4 is equal to the net width along bolts 1-2-4. Given: Fy=248MPa, Fu=400MPa Required: 1. Determine the value of “b” in millimeters. 2. Determine the net area for tension in plates in square millimeters. 3. Determine the design strength for LRFD. 4. Determine the allowable strength for ASD.
