Book Description
The book covers the application of numerical methods to reinforced concrete structures. To analyze reinforced concrete structures linear elastic theories are inadequate because of cracking, bond and the nonlinear and time dependent behavior of both concrete and reinforcement. These effects have to be considered for a realistic assessment of the behavior of reinforced concrete structures with respect to ultimate limit states and serviceability limit states. The book gives a compact review of finite element and other numerical methods. The key to these methods is through a proper description of material behavior. Thus, the book summarizes the essential material properties of concrete and reinforcement and their interaction through bond. These basics are applied to different structural types such as bars, beams, strut and tie models, plates, slabs and shells. This includes prestressing of structures, cracking, nonlinear stressstrain relations, creeping, shrinkage and temperature changes. Appropriate methods are developed for each structural type. Large displacement and dynamic problems are treated as well as short-term quasi-static problems and long-term transient problems like creep and shrinkage. Most problems are illustrated by examples which are solved by the program package ConFem, based on the freely available Python programming language. The ConFem source code together with the problem data is available under open source rules at concrete-fem.com. The author aims to demonstrate the potential and the limitations of numerical methods for simulation of reinforced concrete structures, addressing students, teachers, researchers and designing and checking engineers.

Book Description
Concrete is by far the most used building material due to its advantages: it is shapeable, cost-effective and available everywhere. Combined with reinforcement it provides an immense bandwidth of properties and may be customized for a huge range of purposes. Thus, concrete is the building material of the 20th century. To be the building material of the 21th century its sustainability has to move into focus. Reinforced concrete structures have to be designed expending less material whereby their load carrying potential has to be fully utilized. Computational methods such as Finite Element Method (FEM) provide essential tools to reach the goal. In combination with experimental validation, they enable a deeper understanding of load carrying mechanisms. A more realistic estimation of ultimate and serviceability limit states can be reached compared to traditional approaches. This allows for a significantly improved utilization of construction materials and a broader horizon for innovative structural designs opens up. However, sophisticated computational methods are usually provided as black boxes. Data is fed in, the output is accepted as it is, but an understanding of the steps in between is often rudimentary. This has the risk of misinterpretations, not to say invalid results compared to initial problem definitions. The risk is in particular high for nonlinear problems. As a composite material, reinforced concrete exhibits nonlinear behaviour in its limit states, caused by interaction of concrete and reinforcement via bond and the nonlinear properties of the components. Its cracking is a regular behaviour. The book aims to make the mechanisms of reinforced concrete transparent from the perspective of numerical methods. In this way, black boxes should also become transparent. Appropriate methods are described for beams, plates, slabs and shells regarding quasi-statics and dynamics. Concrete creeping, temperature effects, prestressing, large displacements are treated as examples. State of the art concrete material models are presented. Both the opportunities and the pitfalls of numerical methods are shown. Theory is illustrated by a variety of examples. Most of them are performed with the ConFem software package implemented in Python and available under open-source conditions.

Book Description
Computational Modelling of Concrete and Concrete Structures contains the contributions to the EURO-C 2022 conference (Vienna, Austria, 23-26 May 2022). The papers review and discuss research advancements and assess the applicability and robustness of methods and models for the analysis and design of concrete, fibre-reinforced and prestressed concrete structures, as well as masonry structures. Recent developments include methods of machine learning, novel discretisation methods, probabilistic models, and consideration of a growing number of micro-structural aspects in multi-scale and multi-physics settings. In addition, trends towards the material scale with new fibres and 3D printable concretes, and life-cycle oriented models for ageing and durability of existing and new concrete infrastructure are clearly visible. Overall computational robustness of numerical predictions and mathematical rigour have further increased, accompanied by careful model validation based on respective experimental programmes. The book will serve as an important reference for both academics and professionals, stimulating new research directions in the field of computational modelling of concrete and its application to the analysis of concrete structures. EURO-C 2022 is the eighth edition of the EURO-C conference series after Innsbruck 1994, Bad Gastein 1998, St. Johann im Pongau 2003, Mayrhofen 2006, Schladming 2010, St. Anton am Arlberg 2014, and Bad Hofgastein 2018. The overarching focus of the conferences is on computational methods and numerical models for the analysis of concrete and concrete structures.

Book Description
Das vorliegende Buch behandelt die Anwendung numerischer Methoden auf die Berechnung von Stahlbetontragwerken. Rissbildung, Verbundwirkung und nichtlineares zeitabhängiges Spannungs-Dehnungs-Verhalten der Stahlbetonelemente lassen sich mit der Elastizitätstheorie allein nicht darstellen. Die Erfassung solcher Phänomene ist jedoch für die Untersuchung der Grenzzustände der Tragfähigkeit und der Gebrauchstauglichkeit erforderlich. Dieses Buch gibt eine anwendungsbezogene Zusammenfassung der numerischen Methoden einschließlich FEM. Der Schlüssel dazu liegt in der Beschreibung und im Verständnis des Materialverhaltens. Die wichtigsten Materialeigenschaften von Beton und Bewehrungsstahl und ihre Verbundwirkung werden erläutert. Mit diesen Grundlagen werden verschiedene Elemente wie Stäbe, Balken, Stabwerkmodell, Platten, Scheiben und Schalen behandelt. Dabei werden Vorspannung, Rissbildung, nichtlineares Spannung-Dehnungs-Verhalten, Kriechen, Schwinden und Temperatureinwirkungen berücksichtigt. Für alle Tragelemente werden die jeweils geeigneten Methoden hergeleitet. Dynamische Aufgaben und quasi-statische Kurzzeiteinwirkungen sowie vorübergehende Prozesse wie Kriechen und Schwinden werden gelöst. Die Problemstellungen werden anhand von zahlreichen Beispielen veranschaulicht. Diese sind mit dem Programmpaket ConFem berechnet, welches zusammen mit den Eingabedaten unter Open-Source-Bedingungen unter www.concrete-fem.com zur Verfügung steht. Der Autor zeigt die Möglichkeiten und Grenzen der numerischen Methoden der Baustatik zur Simulation von Stahlbetontragwerken auf. Ein Buch für Studium, Lehre und Forschung, ebenso wie für Tragwerksplaner und Prüfingenieure.
