fib Bulletin 83 “Precast tunnel segments in fibre-reinforced concrete” is now available to purchase from the fib international website.
Reinforced concrete tunnels linings have mostly been traditionally cast in situ, but the development of Tunnel Boring Machines has led to the invention of precast concrete segmental lining technology, which is nowadays one of the most promising applications of Fibre Reinforced Concrete (FRC). A number of large tunnels have already been built around the World with FRC precast linings, and this report presents the experience acquired with these projects, and also provides guidance about the way to apply 2010 fib Model Code recommendations on FRC to these structures. The main drivers of this evolution from RC to FRC are better ductility, more durability, and easier fabrication and construction process.
The 5th fibUK Developments in Structural Concrete (DISC) Conference took place on 29 November 2017 at The Institution of Structural Engineers’ headquarters in London.
fib Bulletin 82 “Precast segmental bridges” is now available to purchase from the fib international website.
With the ongoing development of the PSB concept, it was concluded to be appropriate to develop a Guide to good practice for the PSB construction method. This bulletin was developed by an integrated team of engineers with roots in design, structural engineering, production and construction, and provides a valuable source of knowledge, experience, recommendations and examples, with particular emphasis on the fib Model Code for Concrete Structures 2010 and fib Bulletins 20, 33, 48 and 75.
fib Bulletin 81 “Punching shear of structural concrete slabs” is now available to purchase from the fib international website.

This bulletin contains 18 papers that were presented in three sessions as part of an international symposium held in Philadelphia, Pa., USA, on October 25, 2016.
The papers cover key aspects related to punching shear and an overview of the combined efforts undertaken jointly by ACI 445 and fib WP 2.2.3 to generate test result databanks for the evaluation and calibration of punching shear design recommendations in North American and international codes of practice.
fib Bulletin 80 “Partial factor methods for existing concrete structures” is now available to purchase from the fib international website.
Although the last decades reliability-based assessment of existing concrete structures has gained wide attention in the research field, a consistent reliability-based assessment framework and a practically applicable codified approach which is compatible with the Eurocodes and accessible for common structural engineering problems in everyday practice is currently missing. Hence, in this bulletin two different partial factor formats are elaborated, i.e. the Design Value Method (DVM) and the Adjusted Partial Factor Method (APFM), enabling the incorporation of specific reliability related aspects for existing structures. This bulletin provides a basis for decision making regarding the target safety level of existing structures.
fib Bulletin 76 “Benchmarking of deemed-to-satisfy provisions in standards - Durability of reinforced concrete structures exposed to chlorides” is now available for purchase from the fib secretariat
This bulletin presents the benchmarking of a number of rules for chloride-induced corrosion as given in national codes such as European, US and Australian standards.
It determines the reliability ranges in the chloride-induced depassivation of rebar and provides a reliable database for the performance-based probabilistic service-life design of concrete structures exposed to chlorides.
fib Bulletin 77 “Corrugated-steel-web bridges” is now available for purchase from the fib secretariat
This Bulletin offers the global engineering community a first complete overview of this fascinating technology.
It covers numerous examples of bridges in Japan and France as well as an in-depth case study and analysis of a large corrugated-steel-web bridge in Germany. This publication offers designers, proprietors, contractors and architects alike relevant technical and theoretical information on construction processes along with ideas for future development.
fib Bulletin 79 “Fibre-reinforced concrete: From design to structural applications” is now available for purchase from the fib secretariat
This bulletin provides 45 papers from the FRC 2014: ACI-fib International Workshop on Fibre Reinforced Concrete: from Design to Structural Applications.
The papers are organised in the document under six themes: Design guidelines and specifications; Material properties for design; Behaviour and design of beams and columns; Behaviour and design of slabs and other structures; Behaviour and design of foundations and underground components; and finally, Applications in structure and underground construction projects.
fib Bulletin 78 “Precast-concrete buildings in seismic areas” is now available for purchase from the fib secretariat
This bulletin has a broad scope. Rather than being focussed on design issues, this documents treats precast construction under seismic conditions is treated as a whole.
The main principles of seismic design of different structural systems, their behaviour and their construction techniques are presented through rules, construction steps and sequences, procedures, and details that should lead to structures complying with the fundamental performance requirements for both major earthquakes and more frequent earthquakes.
Bulletin 74 – Planning and design handbook on precast building structures – manual/textbook, is now available to purchase from the fib secretariat.
Bulletin 74 brings the 1994 “Planning and design handbook” up to date by offering a synthesis of the latest structural design knowledge about precast building structures against the background of 21st century technological innovations in materials, production and construction. This handbook aims to help architects and engineers achieve a full understanding of precast concrete building structures, the possibilities they offer and their specific design philosophy. The handbook contains eleven chapters, each dealing with a specific aspect of precast building structures.
Bulletin 75 – Polymer-duct systems for internal bonded post-tensioning – recommendation is now available for purchase from the fib secretariat.
This bulletin updates and amends fib Bulletin 7: “Corrugated plastic ducts for internal bonded post-tensioning”, a technical report published in 2000. The new publication is meant as a cornerstone for the technical approval of polymer (plastic) ducts for internal bonded post-tensioning and possibly for the test procedures of a future testing standard.
fib Bulletin 73 "Tall buildings: Structural design of concrete buildings up to 300m tall" is now available for purchase from the fib secretariat.
Tall buildings are a unique challenge to engineers, even to those with extensive experience of low-rise structures. The bulletin explains the critical interfaces with other professionals, for example architects, building services engineers, façade and lift specialists, geotechnical engineers and wind specialists, highlighting how these parties interact with engineers and can influence and guide the development of the structural solution.
The key factors in choosing the most appropriate structural system are discussed. The bulletin covers the criteria used to select the most economical structural elements including the foundations, the vertical elements and the floor slabs. Examples of common construction methods are presented and their effects on the structural engineering design are discussed.
