CORROSIVE ENVIRONMENT MONITORING FOR BRIDGES IN COASTAL AREA AND STATISTICAL ANALYSIS FOR CORROSIVE FACTORS

Abstract

Corrosive sources, such as water and chrorides, for infractrucrtures are influenced by wind direction, wind velocity, temperature, humidity, rainfall, sea waves and so on. This study discusses relations on corrosive damage on bridges between meteorological data and corrosive responses. With the multiple regression model, the seasonal tendency of corrosive responses is shown; in addition, the evaluation of t-values shows that the simultaneous effects of rainfall and wind predominantly affect to induce corrosive responess.
