Carbon fiber mittens-on-a-string will counteract shear at the tenon ends of the Menokin timbers

Methods for carrying the load of deteriorated joist ends using carbon fiber "mittens", information about the carrying capacity increase with each ply of carbon fiber tape on a timber, and a means of extending timbers with grafted elements like glass after casting an acrylic tooth cap to fit the damaged end of a timber, all designed with the wide-ranging timber damage at the Menokin Ruin in mind, but applicable to many buildings for in-place supplemental strengthening.

Layup and creation of a custom-formed carbon fiber core to replace the rotted center of a beam with crucial and visible tooling, Menokin 2008. John Greenwalt Lee

An overview of carbon fiber uses for strengthening individual timbers or floor systems. Epoxy tape can be used to support weakened timbers, but with vacuum-forming carbon fiber cloth can be form-fit to the core of hollow timbers as well.

Carbon Fiber Repair for Historic Buildings, Intro

Stabilization with carbon fiber is a very cost-effective and preservation-oriented option for deteriorated building elements.
