Commission 1 (COM1) seeks to encourage and develop good practices in the design of concrete structures, with a special emphasis on innovation and imagination. Its work should complement national, regional (e.g. Eurocodes), as well as international codes (e.g. the fib Model Code for Concrete Structures 2010), which in principle give only design specifications.
Scope and objective of technical work
COM1 examines all aspects of specific types of structures, from their structural and architectural design to construction and service life.
COM1 aims to provide state-of-the-art documentation and recommendations for all types of structures where structural concrete plays a significant role. This will apply in priority to fields of development where data and guidelines are not yet available, either new types of structures or implementation of new developments of materials, or a combination of both. COM1 endeavours to promote practices leading to sound, economical, durable and aesthetic design, with special attention to sustainable development principles.
TG1.1 - Bridges
Task Group 1.1 (TG1.1) is dedicated to bridge engineering. All types of bridges are concerned, with a predominance of concrete bridges. Theoretical and practical aspects are treated, as well as construction techniques. Innovations and recent developments but also established good practices are highlighted. Emphasis is placed on bridge architecture and design.
The general objective of the task group is to provide design guides, recommendations, practical design rules and technical advice on bridge design and related construction techniques. Rules of good practice and recommendations for the correct use of materials and techniques are formulated.
WP1.1.1 - Bridges for high-speed trainsWorking Party 1.1.1 (WP 1.1.1) aims to provide guidance for designers of bridges for high speed trains, covering issues such as loads, dynamics, rail deck interaction, wind, slipstream forces, accidental situations, maintenance and inspection, etc. The document will be based on existing guidance edited by the German railway administration. International expertise will broaden the recommendations and bring them to an international level.

WP1.1.4 - Light railway bridgesWhile road and railway bridges benefit from standards and extensive documentation often published by state agencies, it is not the case for lightweight railway bridges. This can be explained by the variety of systems ranging from LRT (Light Rail Transit) to MRT (Mass Rapid Transit) and the fact that these systems are mainly operating at a city or regional level.
However, from a bridge engineering perspective, common features, particular requirements and good practices for design and construction that specifically apply to these transportation modes can be identified.
The general objective of this working party is to provide a state-of-the-art report for the design of LRT and MRT bridges.

WP1.1.5 - Management of of prestressed concrete bridgesOver recent years some significant work has gone into inspection and investigation of post-tensioned bridges around the world. This has led to an increase in understanding the methods of inspection to determine the condition of the prestressing tendons and the whole process to assess structural safety. Some bridges of this type have been repaired and others have been replaced. Long term management of such bridges is becoming important to bridge owners around the world and guidance is scarce.
The working party can collect the current state-of-the-art of such processes from the fib’s member countries and prepare a state-of-the-art report with guidance to assist the countries that are still to embark on inspecting their stock of such bridges.

WP1.1.6 - Design Loads for long span bridgesThe design of long span bridges goes beyond the application range of all the codes of practice and usual construction recommendations. While it is possible to use and extrapolate codes for the design of single elements, it is not the same for the initial definition of data, and especially to fix the loading scheme of the bridge which are not covered by codes.
The goal of the group is to establish a clear philosophy and some basic rules to fix the loading schemes of the bridge in relation to its span length and its typology.

TG1.2 - Concrete structures in marine environments
Well-designed, well-built concrete structures are particularly suited for the marine environment. Task Group 1.2 has so far focused on structures for oil and gas fields in hostile marine environments (fib Bulletin 50); now the focus will be on concrete structures in marine environments in general.
There are additional markets as well, even in urban areas, where societal activities could be effectively located on or in marine concrete structures. For example, artificial islands could be constructed for dwellings, offices, parking lots or other similar needs. Airports have also been considered. Urban infrastructure also has other potential applications, such as submerged floating tunnels, floating bridges and immersed tunnels.
In coastal areas, docks, fish farming, renewable energy and storage may be suitable applications. Ships and barges should also be considered.
WP1.2.1 - Floating concrete structuresIn many cases, floating structures have some clear advantages compared to fixed structures. The motivation of the work in this WP is to demonstrate these advantages, and attempt to draw conclusions as to what applications are particularly promising.The objective of WP1.2.1 is to demonstrate the usefulness of concrete in a modern society where floating structures may be needed. It will identify and consider potential applications of marine floating concrete structures, and then make selections and go into more detail on how the selected applications can be made competitive.

WP1.2.2 - Submerged tube bridgesSometimes our infrastructures need to cross water. Immersed tunnels that sit on the seabed are widely used; more than 100 have been built.Submerged floating tube bridges (SFTB) have never been built. Submerged floating tube bridges are floating bridges, submerged at a defined depth below the water surface. They may be supported between landfalls, either by tension legs or pontoons. They have a closed cross section, like the one of an ordinary tunnel, but they behave like a bridge.The main scope of this working party is to define guidelines for the design of the SFTB, based on the relevant experience.

TG1.3 - Buildings
The use of concrete in Building Structures is widespread throughout the world and is generally well documented in the various national codes and standards. There are however a number of areas where guidance to designers is unclear or where significant interpretation is required. The aim of this task group is to review the current design and construction approaches used and to identify where additional guidance is required. Where it is felt necessary, the group will undertake the appropriate literature searches, review the available current guidance and produce new design advice and recommendations in the form of fib bulletins.
The main goals of TG1.3 main goals are to:
- identify how recent improvements in concrete knowledge and technology are, or could be, applied to building structures;
- prepare state-of-the-art reports, guidelines and recommendations on the use of concrete in the design and construction of concrete buildings.
WP1.3.1 - Structural Design of Concrete Transfer StructuresTransfer structures are often used in building structures as a means of varying load paths through the structure to suit changes in the building grid. Transfer structures typically attract loadings from large areas of a structure and are therefore required to accommodate very large forces. The design of such structures is often outside the scope of normal code guidance and may require a degree of interpretation and engineering judgement. Transfer structures will normally be classified as “Key Elements” and therefore considerations of robustness and progressive collapse are key to their design.The main goals of WP1.3.1 will be to provide a reference document which will describe the types and features of concrete transfer structures and provide information and guidance on their design and construction.

WP1.3.2 - Planning Movement Joints in Concrete BuildingsFor larger concrete buildings, movement joints are necessary to control the effects of drying shrinkage, temperature and creep. The positioning of movement joints is dependent on building shape, positioning of cores and shear walls and can be influenced by construction sequence and pour layout. The presence of joints is a fundamental factor in planning the stability system of buildings.There is a trend in hospitals and other buildings requiring hygienic conditions towards wider spacing of movement joints.The main goals of WP1.3.2 will be to create a reference document that will provide guidance on planning for movement and positioning of movement joints in concrete buildings, with particular emphasis on enclosed rather than open buildings.

TG1.4 - Tunnels
Transportation, mining, water management, energy network development, combined with environmental concerns, have led to a significant increase in the construction of tunnels around the world. Along with other materials, structural concrete plays a primary role in the realisation of these structures, and many issues related to the use of concrete in tunnels ought to be accordingly addressed in order to promote the best use of structural concrete in this field of civil engineering.
The main goals of TG1.4 main goals are to:
- identify how recent improvements in concrete knowledge and technology are, or could be, applied to tunnels, and how new developments in tunnel construction can rely upon concrete technologies;
- prepare state-of-the-art reports, guidelines, recommendations on the use of concrete in tunnel design and construction.

WP1.4.1 - Tunnels in fibre-reinforced concreteThe fib Model Code for Concrete Structures 2010 (fib MC2010) introduced indications for fibre-reinforced concrete, which has led to increased use of fibre-reinforced concrete, particularly in the construction of tunnels. The use of fibre-reinforced in tunnels is one of the main applications of this material both in natural excavated tunnels (mainly in sprayed concrete) and in mechanical excavated tunnels (precast elements).The main scope of this working party is to support the designer in the use of the fib MC2010 for tunnel design. Indications on how to deal with aspects that are not explicitly covered by the fib MC2010 will be given.

WP1.4.2 - Design and construction of openings in precast liningThe realisation of openings in precast lining of tunnels to enlarge the space (creating recesses, etc.) or to build connections with other underground spaces or tunnels requires local disassembly of precast lining segments and cast concrete walls in situ. These areas of the tunnels are subject to specific load conditions, so that the structural requirements should be carefully considered in the design.The construction of the openings also requires special attention, particularly when there is water pressure around the tunnel, in order to prevent water entrance and allow work to be carried out safely. The realisation of the new walls and connections with existing lining segments also needs specific procedures, according to the technology used.

WP1.4.3 - Fiber Reinforced Sprayed Concrete in Tunnels and Underground spacesTunnel and underground spaces lining are more often made using Fiber-Reinforced Concrete (FRC) sprayed concrete. This solution, initially used for temporary structures, is nowadays adopted also for permanent structures. Codes and guidelines for Fiber Reinforced Concrete do not completely cover the sprayed concrete solution. Due to the structural relevance of these applications, it is important to fill in this gap with adequate information.The main scope of the Working Party is to support the designer, construction companies, clients in adopting this technology. Information on the design process, considering aspect as the material characterization and the quality control will be introduced. The indications will refer to Model Code 2010 as a reference document.

WP1.4.4 - Assemblies and fasteningsTunnels are provided with a variety of industry-specific construction products for the connection and assembly of various elements. These items play an important role as regards the construction phase, as well as the safety, quality, and durability in the operation phase of the tunnel structure.Fastenings for catenary installations and heavy suspended equipment are specially treated in tunneling since they are associated with very long life-cycle requirements and load types (long term suspension loads and dynamic/cyclic loads), and because – as historically seen – the failure of such elements poses significant human safety and financial/operational threats.

TG1.5 - Structural sustainability
Recently, sustainability has been discussed with regard to materials, recycling and so on, relating to the reduction of CO2 emissions. However, sustainability has another aspect, for example, the structure, design and construction, which can lead to reducing energy consumption and non-renewable resources over the course of the full life-time of a structure. Minimising energy consumption and non-renewable resources, will be discussed in the context of environmental, social and economic aspects in order to provide sustainable solutions for our society. These discussions will be key for developing sustainable structures. This philosophy is defined as “Structural Sustainability”.
The aim of this Task Group is to focus on minimising energy consumption and non-renewable resources during the life-time of structures from the structural point of view. Basically, the structures built using current specifications are durable. Therefore, structural sustainability should be defined as the difference from existing technologies to new ones in order to make structural sustainability clear. Examples of structural type, detailing, design, special construction techniques and so on for structural sustainability will be collected to publish a state-of-the-art report.

TG1.6 - History of concrete structures
During the long history of CEB, FIP and now fib, the main objectives of their commissions, task groups and special activity groups were and are actual topics of research, application and dissemination.
Construction history is a rapidly growing research field in the community of architects and civil engineers. The last conference on construction history took place in Paris in July 2012 and consisted of 66 sessions. Only two of them focused on concrete and concrete construction. Furthermore, none of the key lectures was related to concrete.
The task group intends to set up a process which shall result in the publication of a series of bulletins covering the global history of structural concrete, from its first developments to the present situation.
At the beginning, it is very important to organise the extremely broad field of historic research. It is suggested to start with a narrower approach, mainly with the collection of historic material. A broader approach implies the integration of concrete history within the time, including political, social, climatic, economic and ecological circumstances. This will require more time as well as the addition of historically educated experts.

TG1.7 - Construction of concrete structures
The areas of interest have been developed from the viewpoint that the construction process has two main components: perception related aspects and process aspects. The perception related aspects comprise materials, workmanship, formwork and scaffolding, curing of concrete, concrete surface, testing and monitoring, high performance concrete, special technologies, specifications and training/education. The process related aspects comprise the construction process of concrete structures, quality management and life cycle management.
The task group addresses state-of-the-art basic principles of the construction process of concrete structures at site. Furthermore, the task group reflects on anticipated developments, which could have a significant influence on construction. The objective is to develop awareness regarding aspects which have an impact on safety, serviceability, durability and environmental issues of concrete structures to be built on site, and to provide information as how to handle the basic principles. The output will be presented as internationally harmonised reports.

TG1.8 - Concrete industrial floors
Concrete is often used for industrial floors that are designed to withstand static and dynamic loads as well as the degradation caused by operations and the environment.
Industrial floor must be properly designed for resisting point and distributed loads due to shelves and vehicles present on the floor. Seismic action transmitted by shelves must be considered in seismic areas.
Shrinkage phenomena play a major role since they provoke early age cracks that can be controlled by contraction joints that are likely to damage due to wheel crossing.
Another important issue is represented by the top finishing layer that had to be properly designed to resist abrasion.
Main scope of the Task Group is to briefly describe the most important issues in concrete technology for industrial floors, give relevant references to important literature, describe important design premises, give guidance to potential improvements and maintenance. Some attention will be also devoted to refurbishing of existing floors.
