Fire Design Of Concrete Structures In Accordance With Ceb Fip Model Code 90

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 book describes how, given the global challenge of a shortage of natural resources in the 21st century, the recycling of waste concrete is one of the most important means of implementing sustainable construction development strategies. Firstly, the book presents key findings on the micro- and meso-structure of recycled aggregate concrete (RAC), while the second part focuses on the mechanical properties of RAC: the strength, elastic modulus, Poisson’s ratio, stress-strain curve, etc. The third part of the book explores research on the durability of RAC: carbonization, chloride penetration, shrinkage and creep. It then presents key information on the mechanical behavior and seismic performance of RAC elements and structures: beams, columns, slabs, beam-column joints, and frames. Lastly, the book puts forward design guidelines for recycled aggregate concrete structures. Taken as a whole, the research results – based on a series of investigations the author has condu cted on the mechanical properties, durability and structural performance of recycled aggregate concrete (RAC) over the past 10 years – demonstrate that, with proper design and construction, it is safe and feasible to utilize RAC structures in civil engineering applications. The book will greatly benefit researchers, postgraduates, and engineers in civil engineering with an interest in this field.

Despite the widespread use of cast-in-place and post-installed anchors in construction, the overall level of understanding in the engineering community regarding their behaviour remains quite limited. Furthermore, since the publication of the original CEB design guide, “Design of Fastenings in Concrete”, ongoing research and additional application experience has led to an improved understanding and deepened knowledge in various areas of fastening technology. fib Bulletin 58 therefore represents a substantial revision of the original 1997 guide. It addresses a variety of loading types and failure modes and takes into account the current state of the art for anchorages in new construction as well as for their use in the repair and strengthening of existing concrete structures. fib Bulletin 58 provides a method for the design of the anchorage and additional rules for the design of the concrete member to which the load is transferred. The specified provisions are based on the currently available research.

Structural design in fire conditions is conceptually similar to structural design in normal temperature conditions, but often more difficult because of internal forces induced by thermal expansion, strength reduction due to elevated temperatures, much larger deflections, and numerous other factors. Before making any design decisions it is esse
