r3.03.04 External pressure forces during large movements

Summary:

A pressure load in large movements is a follower load. By using skin elements, it is necessary to calculate, on the one hand, a second member whose calculation is close to that in short trips, and on the other hand, a term of additional rigidity that is not, in general, not symmetric.
