| Abstract: | Performance – based fire safety design of multi‐storey buildings. In most countries fire design of multi‐storey buildings is still based on the standard temperature‐time curve (ISO 834) which is supposed to cover real fire scenarios on the safe side. A fire safety design considering more realistic natural fires and the redundancies of entire structural systems is risk‐oriented as well as economical. Using international experience and test results and ongoing research of iBMB, a design fire is developed and so‐called real fire curves are derived. They serve as a basis for general calculation methods (according to the Eurocodes) which are able to grasp the real behaviour of structural systems in a fire. A probabilistic safety concept guarantees the necessary reliability of the design taking the probability of fire development, the boundary conditions of life safety and the uncertainties of the design parameters into account. |
