  1. Material Connections

  2. Joining Different Materials • Detailed assemblies include various materials, a detailer must be aware of connection details that combine these different materials, connections may include: • Concrete to masonry • Structural steel to masonry • Wood to concrete • Wood to masonry • Wood to steel • Steel to concrete • Steel to steel • Concrete panel to steel frame

  3. Concrete to Masonry • Concrete plank provides a sub-base for concrete finished floor • Concrete fin fl is bonded to wall with rebar • 3” bearing for concrete plank

  4. Structural Steel to Masonry • Pocket is provided for the steel beam and filled in after beam is set, leveled and anchored to the masonry wall • Note 1” dry pack for leveling beam

  5. Structural Steel to Masonry • Supporting a steel beam on a masonry pilaster (masonry column built into a wall) • Metal plate is set, leveled and anchored to the pilaster then the steel beam is welded to the to the plate

  6. Wood to Concrete • Steel saddle is anchored to concrete (pre-cast tilt-up wall with rebar and ties • Wood glu-lam beam is fit into saddle

  7. Wood to Masonry • Steel saddle is anchored, set and leveled in to the masonry wall with anchor bolts grouted in the cavity of the masonry wall • Dry pack is used

  8. Wood to Steel (Beam clearance not a concern below floor joist) • Method #1 (Joist resting on top of steel beam): stud bolts are welded to the top of the steel beam, a wood plate is then bolted to the steel beam providing a nailing surface to attach the wood floor joist

  9. Wood to Steel(Beam and Joist at same level) • Method #2 (Joist attach to side of steel beam): stud bolts are welded to the top of the steel beam, a wood plate is then bolted to the steel beam, joist hangers are attached to wood plate to hang joist • Hanger also welded to beam • Wood shrinkage a problem

  10. Connection Methods for Wood to Steel • Wood Nailer to Steel beam Wood Jamb to Steel Column

  11. Steel to Concrete • Existing concrete wall to receive a load bearing steel beam • Two methods: • insert expanded metal shields for bolt attachment • drill holes in concrete and insert an approved epoxy adhesive to secure machine bolts to attach steel plate

  12. Steel to Steel • Shop drawings needed for final approval

  13. Concrete Panel to Steel Frame • Panel must be attached to and supported to structural steel

  14. 51/8” x 16” F.S.= full size Canopy Columns Drawing • Design 24” x 24” masonry column • Size Rebar and steel ties • Size glu-lam beam Steel may be used • Add height of wall to bearing support of pilaster
