Check out Simpson Strong-Tie’s Steel Deck Diaphragm Calculator which provides tables of diaphragm shear strengths of a steel deck when using Simpson Strong-Tie screws.
Detailed calculations can be accessed by clicking the desired diaphragm capacity link in the output table. The tables can be developed for combined shear and tension as required by Section 4.10 of the 3rd edition of the Steel Deck Institute Diaphragm Design Manual.
