Simple Connections

Because most structural failures are the result of poorly designed or detailed connections, this is an area which may require additional checks and quality control. Tearing or fracture of the plate at a bolted connection is something that is of critical importance. The below table gives basic expected capacities for such possible tear-outs and is based on the following assumptions:

  • The steel grade has assumed to be 43500 psi or 300 MPa
  • The distance from the center of the bolt to the edge of the plate is based on the size of bolt being used and are as follows:
    • 1/2" Bolt - 3/4" from edge of plate.
    • 5/8" Bolt - 1 3/16" from edge of plate.
    • 3/4" Bolt - 1 3/8" from edge of plate.
    • 1" Bolt - 1 9/16" from edge of plate.
    • 1 1/4" Bolt - 2" from edge of plate.
    • 1 1/2" Bolt - 2 3/8" from edge of plate.
    • M12 Bolt - 20mm from edge of plate.
    • M16 Bolt - 30mm from edge of plate.
    • M20 Bolt - 35mm from edge of plate.
    • M24 Bolt - 40mm from edge of plate.
    • M30 Bolt - 50mm from edge of plate.
    • M36 Bolt - 60mm from edge of plate.
