About this detail

Double glulam beams run continuously over a glulam column featuring a column tenon that remains between the beams. The assembly is secured using Simpson MCT1.9x15 mass-timber connectors with two 1/2-inch diameter by 4-3/4-inch dowels at each column, six 0.220-inch diameter by 10-inch partially threaded screws, and Douglas fir dowel caps at all through-bolts and screw holes. The floor construction includes cross-laminated timber panels per plan, an acoustic mat per architectural specifications, and a concrete topping slab containing radiant tubing per mechanical plans. A one-eighth inch tolerance is maintained, and glulam beams are notched at the column to clear the tenon.
