In Taiwan,many steel and RC structures near the coast have chloride-induced damage.As the service period of structures increases,their safety and serviceability decrease.Restated,the original designed service life and safety reliability depreciate when structures are adversely affected by such environmental factors as chloride concentration and carbonation.However,because earthquakes are common in Taiwan,repairing or retrofitting structures is mainly based on their seismic performance.Unless corrosion reduces the structural safety of a structure,"pre-damage" maintenance work is seldom applied to prevent the serviceability from being reduced by corrosion.Therefore,in structural design,unlike cases that are usually analyzed (e.g.,probabilistie seismic hazard analysis),research is lacking in Taiwan that assesses the environmental hazard in a marine environment.Restated,engineers require a model that can quantify accurately corrosion hazard induced by the marine environment.
