Webtion only for concrete-filled metal decks with aspect ratios of 3:1 or less in structures that have no horizontal irregularities—and it permits diaphragms to be idealized as flexible for … Webstiffness. It is recommended that the aspect ratio (L/W) of the rigid diaphragm not exceed 3:1 if there is a non-composite concrete topping (2 ½” minimum thickness) or 2:1 if there is no concrete topping. If the aspect ratio exceeds these limits, but is not more than 4:1, the diaphragm may be modeled as semi-rigid. chicken little fire engine
