Abstract:In order to study fundamental methods for determining modulus of elasticity (MOE) of structural lumber with vibration methods, the theoretical basis of the measurement is introduced and a hanging style testing system, which consists of an impulse hammer, accelerometer, computer, etc., is built up. It is found that transverse vibration method can determine resonant frequencies of structural lumber specimens effectively. On the specimen, the distance between impact point and detection point should be as far as p… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
