Although masonry walls are a composite of mortar and brick, in numerical simulations the actual composition
is often simplified to a homogenous brick layer. This article studies the impact of the mortar
joints and the interface resistance for a massive masonry wall exposed to climate conditions. Also, a comparison
to the moisture behaviour during an imbibition experiment is made. Whereas during an imbibition
experiment the joints and brick–mortar interface resistances influence the moisture transport
significantly, for real climate conditions a negligible impact is found. Consequently, for the investigated
case a simplification to a homogenous brick layer is allowed.
