Development of lightweight façade systems containing slotted steel girders

Lightweight-building systems can be seen more and more often in Hungary. As one possibility they are used as facade elements of newly built reinforced concrete skeleton buildings or at the reconstruction of existing ones. The lightweight facade system, discussed in this paper, contains slotted steel girders. The girders are produced in Sweden, but due to these special girders the lightweight building system has to be adapted to Hungarian standards and requirements. To adapt the system the different building physics properties have to be examined and based on the calculations construction details must be designed for different types of facades with sectional details and joints to fit the Hungarian circumstances.
