Engineering Cleveland’s First Nine-Story Mass Timber Building

Sarah FitzMaurice, Fast + Epp

INTRO in Cleveland, OH, is on track to be one of the first tall timber buildings constructed using the new Type IV-B construction criteria recently approved for the 2021 International Building Code (IBC). In addition to leveraging the allowances of this future code to construct nine stories of mass timber, which hasn’t been prescriptively allowed in previous versions, the project will expose significantly more of the mass timber than the 20% ceiling limits permitted for Type IV-B construction. This presentation by the timber structural engineer will take a close look at the structural design processes for this under construction project. Topics will include CLT and glulam design checks, such as vibration and connections, grid layout and manufacturer coordination, and how fire-resistance impacts structural members in an exposed tall timber building.
