Abstract: Abstract: Taiwan is located in subtropical region, where temperature
and humidity are relatively high all year round. Besides, the
island is surrounded by ocean that the air-borne salt (ABS)
attack is one of the major concerns for concrete structures. In
this paper, a prediction model for the distribution of air-borne
salt in the coastal region of northern Taiwan is proposed based
on the result of ABS measurement at 38 sites near a period of
four years. The ABS content was calculated monthly based on
the salt concentration, water amount, time, and area of entrance.
The monthly measured ABS of the entire year were
then analyzed to obtain the characteristics of ABS attack in
different conditions. By using the measurements of Chin-Shan,
Keelung, and Lung-Fong sites, 480 data in total were analyzed
by the proposed prediction model. The distance to seashore,
wind direction, effective wind velocity, and effective precipitation
are the primary factors for the ABS distribution.
