Withdrawal Strength of Pneumatically Driven Steel Pin Connections in Cold-Formed Steel Light-Frame Construction
Publication: Journal of Structural Engineering
Volume 144, Issue 1
Abstract
Pneumatically driven steel pins have been successfully used for attaching structural sheathing to cold-formed steel framing in both load-bearing and nonload-bearing applications. The design of these types of connections is exclusively based on published manufacturer data. Attempts to analytically quantify/estimate the shear and withdrawal (tensile) strength of pin connections is nearly nonexistent. This paper proposes a mechanics-based equilibrium model for withdrawal strength and presents test data for wood structural panels connected to cold-formed steel with pneumatically driven steel pins. The tests include a range of wood panel and cold-formed steel thicknesses commonly found in light-frame construction. Using the proposed model, empirically modified to reflect observed behavior, equations are presented to estimate the withdrawal strength of connections made with helically knurled pins. The proposed equations are shown to provide reasonably good estimates of strength with a reliability consistent with that of the more commonly used screw fastener.
