Analysis and Design Rehabilitation Foundation of Timber Houses in Scandinavian Climate Condition

The article describes the analysis and remediation design of the rudiments walls of Wooden construction in the “two by four” system in Central Europe, in particular the Scandinavian climate. This article is focused on the real problems, which these constructions face in similar conditions. Especially in Scandinavian climatic conditions the specific requirements for the solution of this detail must be fulfilled, including the requirements on foundation base frost penetration, minimum interior surface temperature and prevention of the accumulation of moisture in the structure. These structures are facing many bottlenecks already stemming from the architectural and operational requirements that have significant influence on the outcome of the detail. The article is focused on one of the most common structural solutions, which in construction practice could be found mostly in houses built between years 1960 - 1970. The article is focused on the most common rehabilitation of this detail as well. Both of details are subjected to dynamic heat and moisture analysis and analysis of mold growth. The results pointed out on critical solution of the original and rehabilitated foundation and evaluation of the implementing remediation design. To determine the required temperature curve and humidity Wufi 2D software was used.
