About this detail

Connection assemblies for glulam beams, stair supports, and wall anchors occur in an attic level. Wood beams frame into masonry walls using drill and epoxy dowels, hanger brackets constructed from two angles (L4x4x3/8 and L6x4x3/8) secured with six three-quarter-inch diameter epoxy anchors, and strap repairs at joist pockets. Stair support posts hang from framing using custom steel plates, lag screws, and HSS members welded with side plates. Continuous blocking, continuous steel chord plates, and existing wall ties stabilize the assembly. Mortar repair is specified at joist pockets where removed joists occurred, with additional epoxy wall anchors provided between glulam beams.
