ABSTRACT
Bridges located near coastal areas are easy to get decreased their service life by corrosion attack. Airborne sea-salt particles adhered to bridge surfaces are the most influential and they are the reason for a significant section deterioration of bridge members. This paper investigates the amount of adhered sea salt particles at various parts of bridge girder surfaces. As a methodology, a wind-tunnel test was conducted. Bridge model was tested at the two kinds of wind velocity: 5.4m/s & 3.5m/s. Phenol particles were ejected as a role of sea-salt particles. Clearance effect was also tested at three different heights. Results showed the differences of adhered particle amounts at different part of girder surfaces. Finally, four possible methods are proposed to decrease the amount of adhered particles inside the bridge girders.
