Fire resistance of historic iron structures in multi- storey buildings G.G. Nieuwmeijer History of Structural Design Group, Department of Architecture, Delft University of Technology, Delft, The Netherlands Abstract To ensure that there is adequate fire resistance, iron and steel structures in multi- storey buildings (with the exception of the top floor) are usually provided with cladding. However, in historically valuable buildings more often than not it is considered desirable to expose the structure, rather than covering it by a protective layer of insulating material. To achieve this, different philosophies and methods are needed to ensure that there is adequate safety. In the Netherlands the requirements relating to fire resistance in relation to the failure of structures are laid down in the Building Decree. In the stipulations of the Building Decree a distinction is drawn between categories of building that is based on function and also between new buildin
