Bill, Check out the following: 1. Evaluation, Maintenance, and Upgrading of Wood Structures, A Guide and Commentary, ASCE, 1982. 2. Wood Handbook--Wood as an Engineering Material. 3. Stress wave timing nondestructive evaluation tools for inspecting historic structures-A guide for use and interpretation. Documents #2 & #3 are available on line at: http://www.fpl.fs.fed.us/pubs.htm To get a sample identified for species, collect and send a sample to the Center for Wood Research according to the guidelines on: http://www2.fpl.fs.fed.us/WoodID/idfact.html. The samples required for species identification are very small. Just bring a pocket knife. You might also want to browse the web page: http://www.fpl.fs.fed.us/EPW/welcome.htm Basically you need to: 1. Identify the species (send sample) 2. Grade the wood (visual grading per the rules of the species of lumber). 3. Determine the existing condition. 4. Determine the member capacity.
