What you need to know when calculating longitudinal ribs
The longitudinal ribs are calculated by bearing capacity, by normal and inclined sections, for efforts that occur during transportation and installation, and deformations.
When calculating the longitudinal ribs, a large-panel plate is considered as a freely lying beam of the P-shaped cross section. The longitudinal ribs are calculated by the bearing capacity during operation only on the action of uniformly distributed constant and snow loads. The calculated flight of the longitudinal ribs is determined from the condition that the axes of the supports are at a distance of 5 cm from the end of the flooring. Calculation by the bearing capacity for efforts that arise during transportation and installation lead to the influence of only their own weight, taking into account the dynamic coefficient.
