I am analyzing timber roof trusses, investigating the potential of turning current attic space into office space. The building was built in the early 1800's in Urbana, Ohio. Where might I be able to find information about the species of the wood?
Also, some of the larger members have shrinkage checks along their centerlines. NDS does not have any factor to adjust for this, it is typically accounted for in the grading rules for new construction. Since I do not know the grade or species of the wood, how can I incorporate these defects into my allowable stress values? Could they lower any stress values besides Fv, shear stress?
