To design an end plate shear connection, which is commonly used in steel structures, there are several key considerations and steps involved. Here’s a general outline of the design process:

  1. Determine the design loads: Identify the applied loads that the end plate shear connection needs to withstand. This includes the shear force, axial force, and moment at the connection.
  2. Select the end plate dimensions: Based on the loads and the size of the connected members, determine the dimensions of the end plate. The end plate should be large enough to distribute the load effectively and provide sufficient bearing area.
  3. Check for bearing capacity: Calculate the bearing capacity of the end plate. Ensure that the applied loads do not exceed the bearing capacity of the plate. The bearing capacity is typically determined based on the material properties and plate thickness.
  4. Analyze the shear capacity: Calculate the shear capacity of the end plate. This involves considering the shear strength of the plate and any additional shear strengthening methods such as welds or bolts.
  5. Verify the moment resistance: Determine the moment resistance of the end plate connection. This is influenced by the geometry of the end plate and the applied loads. Make sure the connection can resist the required moment without significant deformation or failure.
  6. Check weld or bolt capacity: If welding or bolting is used to connect the end plate to the supporting members, calculate the capacity of the welds or bolts. Ensure that the connections can sustain the applied loads without failure.
  7. Consider additional design factors: Account for factors like corrosion protection, fatigue resistance, and constructability in the design. Specify appropriate coatings, weld details, or bolt arrangements to address these factors.
  8. Prepare detailed drawings: Create detailed fabrication drawings that clearly illustrate the dimensions, weld details, bolt locations, and any other relevant information for constructing the end plate shear connection.

Remember, the design process may vary depending on the specific code or design standards applicable to your region. It’s crucial to consult the appropriate design codes and seek professional assistance if needed to ensure the connection is designed properly and meets all safety requirements.
