Abstract

Method of testing compressive strength of wood using small diameter cores was developed. Special core drill was used to cut 5mm-diameter cores from wood members. Cores were drilled in the direction perpendicular to the fibers and were tested in concave jaws which applied the force in the direction along the fibers. Correlation between strength of cores and the strength of ASTM specimens in compression and tension was established. Introduction In-situ evaluation of structural members is gradually gaining practical importance with the aging infrastructure and number of buildings in service.
