Beam Bears on Column at Notch

Beam bears in a notch at top of column. Beam is connected to top of column with partially-threaded screws.

Purpose: Transfer of vertical load from beam to column.

Design Notes

  • Capacity of connection is dependent on perpendicular-to-grain capacity of the beam.
  • Where the connection design requires a tight connection, installation of connectors should draw the connection tight.
  • Reduced section of column adjacent to notch may be susceptible to damage during shipping and erection. Fully-threaded screws may be used to reinforce the notch. See MTC Solutions’ ASSY Screws as Tensile Reinforcement in Notched Beams.
  • Alignment and tight fit may be difficult to achieve during construction. An erection aid can assist in alignment during installation.
  • It is recommended to detail the top of the column lower than the top of the beam to account for differential shrinkage between beam and column.
  • Consider eccentricity of beam bearing on column where necessary.
  • It is recommended that screws installed in beam and column are slightly overdriven to account for beam shrinkage.
  • Deck not shown for clarity. Beam may require bracing for lateral-torsional buckling.

Other Applications:

  • Beam bears on mass timber wall panel at pocket.
