What are the principles of steel deck replacement

During the use of steel decks, replacement often occurs, and the originally designed steel decks are either unavailable or cost prohibitive. Therefore, the builder wants to replace the problem with similar products, so what is the principle of steel deck replacement?

1. Use the original design deck type as much as possible, because all calculations are carried out according to this deck type, and after the change, there may be structural safety problems;

2. The alternative deck type should be similar to the deck type, such as the rib height and the effective width of the rib spacing are similar, which will reduce the large changes in the structure;

3. The parameters of the substitute deck type should preferably be higher than the original deck type, which will not affect the original design structure and will be safer;

4. The raw material properties of the substitute deck type should not be lower than the original design requirements, including yield strength, galvanizing amount, elongation, etc.;

5. The alternative deck type shall be calculated to ensure the safety of the steel deck and improve the safety of the members.
