Method of proceeding when calculating the durability of multi-elements steel structure type multiplate MP150:>
- define function of structure.
- define of the required durability of the structure
- define of conditions of the environmental aggressiveness(water, backfill, air) - choice the governing corrosion model.
- specifying of the plate thickness with regards to static calculations(acc. to Sundquist - Petterson method)
- specifying of corrosion protection(thickness of zinc coating, paint coating, paved bottoms, etc)
- define of protection layers in upper and lower sphere of the structure with allowance the corrosion progress in surrounding environments with described aggressiveness.
- calculation of durability period of the structure in upper and lower part.
- comparison of the structure durability in the critical parts with the required value.
- decision about acceptance of the structure or about rejection and change of parameters of corrosion protection.
