New App Facilitates Deck Design

Simpson Strong-Tie, a supplier of engineered structural connectors and building products, offers a new Steel Deck Diaphragm Calculator web app that enables engineers to design and evaluate fastener solutions for steel decks given shear and uplift loads.

The app provides diaphragm shear strengths of a steel deck when using Simpson Strong-Tie screws. It features two calculators: One develops tables of diaphragm capacities based on the effects of combined shear and tension, and the other provides fastening solutions for a given shear and uplift.
Once an engineer chooses a preferred design solution, the app produces a submittal package that includes fastener information, code reports, Factory Mutual reports, Appendix VII of Steel Deck Institute’s Diaphragm Design Manual, Third Edition (SDI DDM03), coating information and tools for installation.
