ENABLE DESIGN MODELING FOR CORRUGATED STEEL DECK DIAPHRAGMS

Section 12.3 of ASCE 7 - 22 states that unless a diaphragm can be idealized as either flexible or rigid, structural analysis should explicitly include consideration of the stiffness of the diaphragm (i.e. semirigid modeling). I am publishing an article in a technical magazine in which I describe how I use STAAD to determine seismic shear stresses and lateral deflection in a model based on the deck's gage, span, shear modulus, system of fasteners, and an equivalent steel plate of uniform thickness. I attached a copy of my article to your service request form #CS0525388 and received a response from your viewer that said my "methodology is valid and I should submit this idea to you for enhancing your STAAD software". The need to accurately identify steel deck shear stresses and lateral deflection is critical to the structural design of our projects here at Carollo Engineers, particularly in high seismic areas. I would be happy to review the methodology with your software development engineer, if you wish.
