“…For the model wall, this is approximately 200 K, regardless of the aggregate type used. This effect has already been described by Klingsch and Toris [21]. During heating, the heat flow is clearly directed from the surface to the interior of the component.…”

Concrete is the most widely used building material. Particularly in industrial floors or air ducts in steel and foundry industries, it is often exposed to high continuous or cyclical temperatures. In these applications, high temperature resistance of the concrete is essential to ensure high bearing capacity and durability. In addition to the temperature level, the composition of the concrete is also important regarding long‐term stability of the exposed concrete members.This study investigates the effect of slag cements as well as granulated and air‐cooled blast furnace slag as industrial aggregates on the hot and residual strength of concretes exposed to temperatures up to 700 °C. In addition, the material parameters determined were transferred to the component level to calculate the bearing capacity of model walls. It was shown that the hot and residual strength, as well as the bearing capacity at the component level, are high when concretes are made from these materials. The characteristics are comparable to those of concrete made with thermally stable but relatively expensive basalt and even significantly better when quartzitic aggregates were used. The results allow suggestions to be made for additions to current fire resistance design codes.

As a result of the powerfully increased international fire research during the last decades, more and more components and systems within fire safety engineering are becoming amenable to analytical and computer modelling. The most manifest verification of this development probably holds for the fire engineering design of load bearing and separating structures.The paper begins with a general survey on the characteristics of a reliability based structural fire engineering design. Then, the physical model, describing the simulated real fire exposure and the thermal and mechanical behaviour of the structure, is commented on with regard to the present state of knowledge and the need of further research. Finally, the different uncertainty sources in the design process and the principles of a cost-benefit optimization are dealt with and exemplified.
