About this detail

A mass timber column-to-floor connection incorporates a glulam column above and below a CLT panel topped with concrete over an acoustic mat and architectural finishes. A hollow structural section stub and shear tab connection welded with one-quarter inch fillet welds on the outside edge is provided at the node. A one-sixteenth inch thick by full column size washer plate with a center cutout and oversized holes for threaded rods is installed on the top side of the CLT prior to landing the upper column. Optional shop-installed FSZ structural screws angled at forty-five degrees are specified at sixty-four per node based on panel selection and peer review. Site tolerances, steel plate machining, and shim washer requirements for elevation adjustments are explicitly noted.
