Fip Ceb Recommendations Tor The Design Of Reinforced And Prestressed Concrete Structural Members Tor Fire Resistance

The first draft recommendations for the design both of reinforced concrete and prestressed concrete structural members in regard to fire resistance were presented for discussion at the Sixth FIP Congress held in Prague in 1970 at an open meeting of the FIP Commission on Fire Resistance under the Chairmanship of Professor K. Kordina. These have been subsequently discussed and elaborated at meetings of the Commission in Paris, Brunswick and London and a final draft was agreed at the Seventh FIP Congress held in New York in 1974 for the publication to include both normal dense and lightweight concrete. The inclusion of reinforced concrete has been at the special request of CEB who had expressed a wish for detailed recommendations to be available for inclusion in their next revision of the CEB/FIP International Recommendations for the design of Concrete Structures. The recommendations give detailed advice to the practising engineer on how to design structural elements to withstand the standard fire loads for stated periods which may be prescribed by building authorities on a national scale. The values given are safe values based on the results of research and testing on individual elements in a standard furnace. Analytica! methods of assessment of fire resistance are being developed which take into account the interaction of structural members and these may well lead to further economy. Further investigations of the effects of continuity and end-restraint by the Commission may enable these recommendations to be revised in the future.

This volume provides a description of units, fibre reinforcement materials and technologies used to produce units with wall thicknesses from 5m to 40mm. The risk factors and long term effects are also described.
