I am not aware of a formula to compute or predict the life expectancy of buildings.

It does not admit mathematical analysis.

Modern RCC buildings that are not abused or subjected to extreme conditions like massive earthquakes of unprecedented magnitude or fires or floods or previously unheard of hurricanes or terrorist attacks, can safely be assumed to have 100 years as a useful life, provided standard and routine maintenance is done.

Possibly it will last even longer.

Of course individual components like the painting, plaster, or roofing tiles or glass or fittings like pumps, diesel generators etc have standard rated life spans but the frame as a whole will easily last at least 100 years for any structure designed and built using modern design practices, and current code specifications and with materials available today.

I hope this answer is useful.

This answer was edited.Redundant Truss: It is a truss that includes a maximum number of structural members more than the requirement. Using the equation of equilibrium, it is impossible to analyze. It is a statically indeterminate type of structure. Thank You.
