The OP mentioned that there ate 3 frames in the short direction, meaning aspect ratio for the diaphragm is less than 2. You don't … 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. dog ate my cereal
