A Better Way to Assess the Capacity of Our Wooden Built Heritage: Guide to the Structural Evaluation of Existing Timber Structures
Timber structures, from barns to old industrial facilities, tell important community stories, but are often at risk of being lost because of perceived limits to the future strength of the timbers through deterioration or adaptive use needs. The 2019 Guide to the Structural Evaluation of Existing Timber Structures, created by the Timber Framers Guild, establishes a methodology for maximizing the assessed capacity of lumber and timber framing, helping to reduce expensive and potentially character-modifying alterations to the framing of our historic buildings undergoing repair and adaptive reuse. Tom Nehil will present key information provided in this guide, laying out an acceptable practice for evaluation of existing structures, and explaining why it is necessarily different than design of new timber structures. This approach enables the investigator to tap into the “hidden capacity” of the timber that accounts for the high level of performance and longevity of many timber structures. This session will benefit engineers and investigators directly involved in structural assessments and also owners, architects, and builders wishing to understand the process better and hire the work done well.

This webinar is supported in part by an award from the Michigan Council for Arts and Cultural Affairs and a grant from the Michigan Preservation Fund of the Michigan Historic Preservation Network and the National Trust for Historic Preservation.
