Abstract

Procedures have been recommended–such as in the National Design Specification–for design of bolted joints in wood members where the side members are thicker or thinner than half the main member thickness. However, these recommendations have had no experimental verification up to now. The same is true for joints with other than three members. This study experimentally verified present rules for handling three-member and multiple-member joints, but found that present rules for two-member joints were inadequate.
