چکیده
The embedment strength performance of the self-tapping screw (STS) connector, used as a cross-laminated timber fastener, was evaluated considering tree species’ density and load direction parameters. STS had diameter 8, 10, 12 mm. Considering characteristics STS, threaded area shank were compared. A larger resulted in higher yield all directions respective wood. effective can estimate more accurate value for strength. longitudinal cross section than that radial tangential sections. For loading direction, ratio parallel perpendicular to grain specimens 0.40 0.58 by wood species. predicted based on specific gravity fastener differed considerably 38% 56% from actual using area. This paper provides data setting adjustment factors predicting connection.
