Analysis of SCM Sill Beam Reinforced with Steel or Titanium Profile

Minimization of the demand for energy which is needed to heat a building is an important issue of a sustainable development policy, therefore mutual exchange of heat between the interior of the building and its external environment through a window as well as its mounting parts is one of the most important issues of energy calculations.In the paper, the SCM (Quick Warm Mounting) sill beam used as a support for a window installed in a thermal insulation layer is analyzed. Due to the fact that titanium has a more favorable specific strength, lower coefficient of thermal conductivity and much higher resistance to corrosion than steel, the currently used steel reinforcement of the SCM beam was replaced by a titanium one. Numerical calculations were performed using the ADINA System, which is based on the finite element method (FEM). The process of heat exchange between the interior with the constant temperature of 20°C and the external environment with the constant temperature of -20°C is analysed. The temperature distribution in the wall, the dew point temperature as well as corrosion and economical aspects associated with the use of titanium profiles are discussed.
