Structure Life Span Calculation. - SURTREAT

Structure Life Span Extension Calculation. If the average rebar diameter at time zero is 0.75 inches or 19 mm and the average corrosion current is 3.5 A/cm and the average hotspot current is 8.8 A/cm the time required for the loss of 15% ( a conservative point below the critical point) of rebar diameter can be calculated as follows.

Life-Cycle Costs | American Institute of Steel Construction

Structural Steel provides long-term durability with lower-life cycle costs. Life-cycle costs encompass initial construction cost, routine maintenance and any future restoration costs of a structure. When protected and maintained properly, steel provides long-term durability and a lower life-cycle cost to the owner, making it an economical and sustainable choice.

What is the design life span of a building? - Quora

The corrosion of steel reinforcements drastically reduces life span. So without specifications, it would be hard to give an estimate for a life span. But an average value for life span would be around 65 to 70 years. Now most building codes use probabilistic approach for design of structures.

The new client has asked that we define which steel to use (we've narrowed it down to 304 or 316 stainless steel), and that we estimate the lifespan of the plate structures. For the most part, the structures will be subject to ground snow load (in the 60psf range) yearly and otherwise be untouched and unloaded as the covers are extremely remote.

Predicting the service life of galvanized steel

Zinc, which has been used to hot-dip-galvanize steel for 250 years, provides 50 to 75 years of corrosion protection in many environments. Empirical data collected about hot-dip galvanized (HDG) steel field performance from 1940 to 1980in environments ranging from industrial to marine to suburbanindicates that zinc can prevent base steel corrosion more than other surface treatments.

Estimating The Life Of Hot-Dip | American Galvanizers , life span 70 years steel structure

This can be done through repairing the rusted areas with paint or re-galvanizing the surface entirely.
