The first part of the report is devoted to linear elements (beams, columns) and includes chapters on shear and flexure in beams, ultimate limit state design of prestressed beams, and of reinforced concrete members under combination of bending with axial load and shear, of beams subjected to torsion, and a chapter on shear design based on truss models with crack friction. The second part treats two-dimensional elements and includes background information on ULS design of wall, shell, and slab elements. lt concludes with a chapter on axisymmetric punching of slabs.

The 1996 FIP Recommendations Practical Design of Structural Concretewere finally published by SETO in September 1999. They had been developed based on the 1990 CEB-FIP Model Code. The main objective of this Bulletin is now to demonstrate by practical examples the application of these recommendations, and especially to illustrate the use of strut-and-tie models for designing discontinuity regions in concrete structures. These examples represent also a continuation of the 1990 FIP Handbook on Practical Design that had been based on the former (1984) version of the recommendations. Most of the examples are recently built existing structures. Although some of them may be considered as quite important, the chosen examples are by no means exceptional. The technical report does not deal with the discussion of aesthetic or general conceptual aspects. On the contrary, the main aim is to treat particular design aspects by selecting local regions of the chosen structures, that are then designed and detailed following the design principles and specifications proposed in the 1996 FIP Recommendations mentioned above. The document is believed to be of interest to all engaged in the design of structural concrete. It hopefully supports the use of more consistent design and detailing tools like strut-and-tie models.

Serviceability limit states are essential for appropriate function and durability of concrete structures. The attention is paid especially to the stress limitation, crack width analysis and deflection analysis. The document provides supplementary information to the fib Model Code 2010 (MC2010), where a limited space did not allow for a detailed description of individual procedures. The principles used in MC2010 in chapter 7.6 are explained in detail within this document. The stress analysis is focused on stresses in concrete and steel including the stress redistribution due to the long-term load and cracking of reinforced concrete and prestressed concrete elements. Crack width analysis explains the mechanism of cracking under mechanical loading and due to deformation restraint. Cracks in prestressed concrete elements are also discussed. Deflection analyses with different levels of accuracy are described including the shear effects. Examples illustrate the practical application of rules defined in the MC2010 of individual serviceability limit states. Simplified and more general methods are used. An important part of the bulletin shows the development and extension of the serviceability limit states after publishing of the MC2010 and alternative approaches. Special attention is paid to deflections of prestressed concrete beams, shear effects on deflection, slenderness limits and influence of the concrete cover. The final part deals with an application of numerical simulations.

The introduction by the Task Group's convenor L. Taerwe 'Model uncertainties in reliability formats for concrete structures' gives an outline of the general approach summing-up his former contribution to CEB Bulletin 219 'Safety and Performance Concepts' on the consistent treatment of model uncertainties in reliability formats for concrete structures. The second contribution 'An analysis of model uncertainties: ultimata limit state of buckling' by M. Pinglot, F. Duprat and M. Lorrain investigates the model uncertainties of hinged columns and the influence of boundary conditions and proposes appropriate safety elements. The third contribution 'Model uncertainties concerning design equations for the shear capacity of concrete members without shear reinforcement' by G. König and J. Fischer compares suggested formula from various sources (CEB-FIP Model Code, Eurocode 2,Remmel) to 176 test results from a data base covering concrete strengths from 20 to 111 MPa.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 549: Simplified Shear Design of Structural Concrete Members examines development of practical equations for design of shear reinforcement in reinforced and prestressed concrete bridge girders. The report also includes recommended specifications, commentary, and examples illustrating application of the specifications. NCHRP Web-Only Document 78 contains extensive supporting information, including a database that can be used to compare the predictions from the recommended procedures to existing design procedures"--Publisher's description
