A Consideration for the Durability of Paint Films on Railway Steel Bridges

概要

In order to offer the effective painting maintenance for railway steel bridges, we tried to predict the service life of paint films. The steel bridges were classified into ten groups from the factors such as the kinds of steel plates (mill-scale or blasted), environments (sea or others) and the periods after painting (newly-constructed or repainted). From the results of the degradation of the paint films for about 100 steel bridges in conventional lines, the equation for the service life of each group was estimated by the regression analysis with conditional variance.
