Combined Lateral & Withdrawal Load on Fasteners

Design for simultaneous lateral and withdrawal forces on dowel-type fasteners with proper interaction checks.

Design connections subject to simultaneous lateral and withdrawal forces with CalcBook’s interaction-based module. The software applies the correct interaction equations for each fastener type and load direction. Perfect for sloped or uplift-loaded connections where withdrawal can’t be ignored.
