Evaluation and Upgrading of Wood Structures: Case Studies : Proceedings of a Session at Structures Congress '86

The need to evaluate and upgrade existing wood structures stems from concerns of safety and serviceability. These concerns are caused for a variety of reasons which include plans for continued use of an existing structure after a long loading history, occurrence of damage/deterioration due to any one of numerous factors, imposition of higher service load demands, and requirements to adhere to new code provisions. The increasing replacement cost of existing wood structures often warrant that the rehabilitation of the existing structure be carefully considered as an alternative to building a new structure. The process of evaluation and upgrading of existing wood structures provides few alternatives and demands a good appreciation of the methods and material involved in implementing the solution. This volume is a collection of papers which deal with a variety of case studies in enough detail to serve as an excellent reference for practicing structural engineers. Cases involving the restoration of hangars, upgrading of wood trusses, epoxy repair of timber beams, nondestructive testing of piles and structural elements, and decay in wood structures are covered.
