A new solution is proposed to the described problem. Its essential features are described below.
- All steel elements of a building structure that bear any essential forces are adequately cooled to keep their temperature within the selected limits at any circumstances, including a huge fire.
A liquid, preferably water, is used as a cooling fluid. Its latent heat of evaporation can contribute to the cooling if necessary and opportune.
The cooling fluid flows through internal channels in the cooled steel elements. Such channels are connected, as far as necessary, in series to flow paths along the flow direction. Several flow paths can be, on their turn, connected in parallel to an assembly in which every flow path starts in a common fluid distributor and ends in a common fluid collector. A building can need several such distributors and collectors.
