Description

The Timber Frame Engineering Council in 2019 issued TFEC 3 “Guide to Structural Evaluation of Existing Timber Structures” to provide guidance to engineers and investigators engaged in the assessment and repair of existing timber structural systems. This guide is also directly applicable to rehabilitation and adaptive reuse of older timber structures. The National Design Specification for Wood Construction (NDS) is the source for allowable design values for structural design of new timber structures; it is not intended to provide information specific to existing structures. When working with existing timber structures, more detailed information is available to the engineer regarding wood species, grade characteristics and conditions of use. This additional information is helpful for determining the most appropriate design values for the timber.

This presentation will discuss key information provided in TFEC 3, 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.

Course will award 1.5 hours of continuing education
This course is Diamond Review approved in 49 states. New York does not accept hours from recordings.
