Abstract:Field measurements are executed on RC structure of a salt electrolytic plant which has been in service for 20 years.Laboratory experiments on mechanical properties of the corroded RC members are carried out as well.Based on the field test and laboratory experiments,rational safety evaluation is achieved.Retrofitting plan is designed.During the past 8 years,the strengthened structure works well all along,which proves that the retrofitting plan is effective.
