A practical method for durability design of marine concrete structures treated with silane

Despite its wide application in engineering practice, silane impregnation is usually regarded as an additional protective measure and not quantificationally considered in current design codes. To bridge this gap and increase the rationality of durability design, this paper presents a practical design method based on a probabilistic model. In the proposed method, the protection effect of silane can be converted into an extra layer of concrete cover and help to reduce the cover thickness designed in the conventional approaches. With characteristic values and partial factors determined for specified cases, the design procedure is illustrated and the effectiveness of the method is verified through comparisons with the fully probabilistic method.
