Abstract

This paper examines the accuracy of a recently developed hygrothermal-corrosion model which predictsthe corrosion of fasteners embedded in wood by comparing the results of the model to a one year fieldtest. Steel and galvanized steel fasteners were embedded into untreated and preservative treated woodand exposed outdoors while weather data were collected. Qualitatively, the distribution of corrosionproducts along the length of the fastener were in agreement with the simulation results. Quantitatively,the combined hygrothermal-corrosion model predicted 20% less corrosion than measured in the exposuretest for galvanized steel fasteners due to a lower simulated moisture content.
