Prepared by the Subcommittee on Evaluation, Maintenance, and Upgrading of Timber Structures of the Committee on Wood of the Structural Division of ASCE. This report presents information on technical aspects of inspection, evaluation, reinforcement, repair, and rehabilitation of timber structures. Any structure, regardless of the material from which it is made, may be subject to a review of its ability to perform a specific function or functions. This report reviews factors that influence the serviceability of wood structures, including loadings, duration of loads, temperature, moisture and weathering. Effects of chemicals and fire, as well as insects, fungi, and other organisms that attack wood are also covered. Designing to avoid problems caused by these factors is discussed. Inspection techniques and equipment are described, along with guidelines on where to look and what to look for. A section of evaluation of wood structures includes criteria such as structural analysis, determination of loads, and estimating load carrying capacity.For both bending and tension specimens after repair, the joints consistently reached an ultimate strength of 30%-60% greater than the original strength ... The primary problems associated with these repairs were the difficulty of detecting all rot, anbsp;...
