Curious about this garage. 20x24, originally roof and walls were tied together by 2x4 rafter ties. TJI was added down the center with full length 2x12s on either side as web stiffeners. Both ends of the Tji are supported by 4x4 posts bearing weight, and 2x8s tied to the 2x12s with joist hangers 24” on center on either side as ceiling joists, and 4x4 posts mounted on top tied to the ridge beam. Collar ties and rafters ties added back. Finished with a drywall ceiling and fiberglass insulation. Will this hold up?
