Web2. AISI S310/DDM Calculations for Shear Stiffness Corrugations in the diaphragm cause reductions in the in-plane shear stiffness below that of an equivalent flat plate, and the estimate for the reduced shear stiffness is essential for design. The deformations in a shear loaded diaphragm are assumed to be composed of deformations from pure WebFor concrete-filled steel deck diaphragms, methods provided in AISI S310 (AISI, 2024) to calculate stiffness have relied on empirical formulas while past research by Porter and Easterling (1988) suggests that mechanical models and theoretical formulas can accurately capture stiffness.
