Group 2. Beam to Column Connections
Design concepts. All connections in the group must
hold the beam in place on top of the column. Shear transfer
is reasonably easy to achieve. Some connections must also
resist some beam uplift. Finally, for cases in which the
beam is spliced, rather than continuous over the column,
transfer of forces across the splice may be required.
6. Custom welded column caps can be designed to transfer
shear, uplift, and splice forces. Note design variations to
provide sufficient bearing area for each of the beams and
differing plate widths to accommodate differences between
the column and the beam widths.
4. Simple steel dowel for shear transfer.
7. Combinations of steel angles and straps, bolted and
screwed, to transfer forces.
5. Concealed connection in which a steel plate is inserted
into a kerf in both the beam and the column. Transverse
pins or bolts complete the connection.

8. A very common connection – beam seat welded to the
top of a steel column.
