    COM2: Analysis & design

Motivation

Analysis and design are understood as core tasks of structural engineering. In this field, nine areas of interest have been identified; hence, nine task groups form the basis of the new structure of Commission 2. Today, the analysis – i.e. the detailed investigation of the stress and strain state – has gained in importance, and consequently refined and physically based models and calculation procedures are required. On the other hand, the design of new structures (comprising conception, dimensioning and detailing) still is fundamental for practicing engineers. In general, the respective approaches should be one and the same for the two levels of detail, but more practical and easier to apply for the latter case. Commission 2 supports and follows this line of development of structural engineering.

Scope and objective of technical work

The scope of Commission 2 is to develop models and calculation procedures for the analysis and design of structures and structural members under short term and long term static loading as well as under fatigue, fire and extreme events. Serviceability limit states and ultimate limit states as well as their interaction are considered, and both research results and recommendations for the practical application shall be presented. In the near future the activity of COM2 will focus on new and also on existing structures in order to support the development of the new fib Model Code 2020.

  • TG2.1 - Serviceability models

    Serviceability limit states (SLS) determine the applicability of concrete structures. When these criteria are met, the concrete structure can function properly during its service life. Correct design according to serviceability limit states is therefore essential for the construction of durable, robust and valuable structures. Violation of the SLS criteria leads to structures that do not function properly and/or to reduced durability, the consequences of which can be recognised very quickly. Therefore, the models for verification of the expected criteria are of primary importance.

    The activity of the group is focused on the development of models for analysis of cracks and deformations of concrete structures. Beside the sophisticated numerical models, engineering practice requires practical engineering approaches, which are applicable in codes and in preliminary design stages when important decisions on the conceptual design are accepted. The activity will be focused on new structures and also on existing structures for assessment, rehabilitation or strengthening.

    • WP2.1.2 - Restrained and imposed deformations
       
      The main objective of Working Party 2.1.2 is to present practical recommendations for the design of reinforced and post-tensioned concrete structures to accommodate the effects of restrained and imposed deformations. This involves looking into the causes of internally-induced and externallyimposed deformations and point out their different influences on the structural behaviour. The WP will assess various effects that may affect the degree of restraint such as superimposed loading and presence of prestressing, and propose modifications to existing design criteria where relevant.
       
      Guidance will be given on the use of nonlinear response analysis for rigorous response prediction.

  • TG2.2 - Ultimate limit state models

    Task Group 2.2 was established to evaluate and develop models for the conception, design and analysis of concrete structures. Topics within the scope of the work may include models that deal with the ultimate limit state and with ductility as to their affect on peak and post peak behaviours.

    The objective of TG2.2 is to synthesise available results from research, testing and design experience. Therefore, research and development in this field is monitored, documented and evaluated. For the time being, the work is focused on the behaviour of slabs and beams in shear, shear aspects in the design of members reinforced with steel bars, steel fibres or a combination of steel fibres and bars and the punching behaviour of slabs. Moreover, strut-and-tie modelling is treated as a specific method to capture ultimate limit states.

  • TG2.6 - Composite steel-concrete construction

    Steel-concrete composite construction allows various structural solutions that optimize the performances of the two-component materials through a well-assessed design that takes into account all the particularities of steel and RC constructions as well as interaction problems.

    The use of composite construction is widely spread all around the world, and its use for the construction of medium-sized bridges is a very frequent technical choice. In this historical period, the concrete industry must take this into account.

    The motivation of the fib TG2.6 is to identify the meaningful characteristics of composite steel- concrete structures with respect to typical aspects of RC structures in order to provide technical knowledge and design provisions.

    The activity of the group is focused on the analyses of the structural behaviour of RC parts constituting steel-concrete composite members and the modeling of their interaction with the steel parts.

  • TG2.8 - Safety and performance concepts

    The overall motivation of Task Group 2.8 (TG2.8) is based on the fact that structural systems are typically designed to stay in service for at least several decades. This implies that proper attention must be given to structural performance under various actions, both man-made and environmental, to the methodology of structural analysis and assessment, to material properties, to the inverse identification and monitoring of structural resistance among others. The main focus is the development of a holistic performance based design approach for new and existing structures and infrastructures.

    The objective of TG2.8 is to promote and to provide on the basis of the guide to good practice “safety and performance concepts – reliability assessment of concrete structures” the theoretical and practical developments for the performance based design. This includes structural safety, serviceability and reliability, advanced methodology including probabilistic methods, inverse analyses techniques, monitoring methods, and performance and optimised life-cycle cost based design concepts.

  • TG2.9 - Fastenings to structural concrete and masonry

    The modern fastening technique is employed extensively for the transfer of concentrated loads into concrete and masonry structures. Cast-in-place anchors, placed in the formwork before casting of the concrete, as well as post-installed anchors and reinforcing bars, which are installed in hardened structural concrete or masonry, are equally common. Loads are transferred into the concrete or masonry by mechanical interlock, friction, bond or a combination of these mechanisms. However, independently of the load-transfer mechanism, all anchorages rely on the tensile strength of the concrete or masonry, a fact which must be taken into account in both assessment and design. Despite the widespread use of cast-in-place as well as post-installed anchors and reinforcing bars in construction, the overall level of understanding in the engineering community regarding their behaviour remains quite limited.

    In order to improve the general state of knowledge in this field, Task Group 2.9 “Fastenings to Structural Concrete and Masonry” (former Special Activity Group 4) was formed.

    The aim of TG2.9 is to collect and discuss the latest research results in the field of fastening technology, to identify new areas of research and to synthesise the research results in harmonised provisions for the design of fastenings.

  • TG2.10 - Textile reinforced concrete construction and design

    New material composites such as textile/carbon reinforced concrete have been developed during the past two decades. Textile reinforced concrete is a composite material where the concrete is reinforced with textile structures instead of classical reinforcement steel. Apart from alcali resistant glass and similar materials, carbon has become the prevalent reinforcement material and lead to the development of so-called carbon concrete. Carbon textile fabrics as well as carbon bars are used as reinforcement material for carbon concrete. Carbon's resistance to corrosion allows an enormous reduction of concrete cover thickness in comparison to classical steel reinforced concrete.

    These developments offer new ways in concrete constructions due to the possibility for curved, thinner and more filigree construction components. This might be a starting point for several new research work. Therefore, the work of a task group is considered meaningful. The task group "Textile reinforced concrete" will mainly (not exclusively) deal with carbon reinforcement. The task group may contribute in working out rules and compiling guidelines for the design of constructions made of the new composite material textile/carbon reinforced concrete.

    The objective of the proposed task group is construction and design of textile reinforced concrete. Regarding the reinforcement material, carbon is in focus. The aim of the task group is to contribute in working out rules and compiling guidelines for the design of constructions made of textile/carbon reinforced concrete.

  • TG2.11 - Structures made by digital fabrication

    Digital fabrication processes for fabricating concrete-like products, objects and/or structures are typically grouped into three main categories: (i) Layered Extrusion (e.g. contour crafting, concrete printing etc.), (ii) Binder Jetting (e.g. D-shape), (iii) Slip-forming (e.g. smart dynamic casting). However, to date, many important developments have been accomplished for layered extrusion technology, consisting of a digitally controlled moving printing head (or nozzle) that precisely lays down the concrete or mortar material layer-by-layer.

    It is clear that the full understanding of the structural performances of digitally fabricated elements represents noteworthy progress in supporting the design of such innovative structures. In this way, reliable structural concepts and assessment methodologies could be integrated within existing international building codes/standards and adapted to the particularities of DFC, providing effective recommendations to the construction industry stakeholders.

    The primary objective of the task group is to identify limiting aspects of the current design practice for the implementation of novel, digitally-fabricated concrete structures. Based on that, the task group will address fundamental structural issues related to the particularities of DFC with the final aim of providing effective guidelines for code-compliant applications.

  • TG2.12 - Protective Concrete Structures against Hazards

    Concrete structures are suitable for the development and construction of protective structures against several kinds of hazards, like a blast, missiles, impact or thermal loads. The reasons for such extreme loadings may be different, but the structures under consideration have to provide conditions for safe and relatively comfortable survival of people inside. The TG2.12 will develop documents which specify the conditions of performance of protective structures and conditions for their design.
