Book Description
Covers all the soil mechanics and foundation engineering topics that are commonly included in civil engineering degree courses, and provides a number of springboards into related advanced topics. Although it is intended principally to satisfy the needs of student civil engineers, this guide should also prove useful to those practicing engineers who are unaware of the powerful and elegant reconstruction of the subject which has been made possible by the recent concepts of plasticity, dilatancy and critical states.

Book Description
This book analyses the current knowledge on structural behaviour of RC elements and structures strengthened with composite materials (experimental, analytical and numerical approaches for EBR and NSM), particularly in relation to the above topics, and the comparison of the predictions of the current available codes/recommendations/guidelines with selected experimental results. The book shows possible critical issues (discrepancies, lacunae, relevant parameters, test procedures, etc.) related to current code predictions or to evaluate their reliability, in order to develop more uniform methods and basic rules for design and control of FRP strengthened RC structures. General problems/critical issues are clarified on the basis of the actual experiences, detect discrepancies in existing codes, lacunae in knowledge and, concerning these identified subjects, provide proposals for improvements. The book will help to contribute to promote and consolidate a more qualified and conscious approach towards rehabilitation and strengthening existing RC structures with composites and their possible monitoring.

Book Description
High strength fibre composites (FRPs) have been used with civil structures since the 1980s, mostly in the repair, strengthening and retrofitting of concrete structures. This has attracted considerable research, and the industry has expanded exponentially in the last decade. Design guidelines have been developed by professional organizations in a nu

Book Description
The in situ rehabilitation or upgrading of reinforced concrete members using bonded steel plates is an effective, convenient, and economic method of improving structural performance. However, disadvantages inherent in the use of steel have stimulated research into using fiber reinforced polymer (FRP) material in its place, with the goal of providing a non-corrosive, more versatile strengthening system. Strengthening of Reinforced Concrete Structures presents a detailed study of the flexural strengthening of reinforced and prestressed concrete members using FRP composite plates. This book covers short and long term performance through model and full-scale experimental testing plus theoretical and numerical considerations. It discusses previous investigative and site work undertaken to strengthen concrete beams using steel bonded pates and the pros and cons of using the steel and composite plate materials. It also presents case histories of construction members upgraded or strengthened using carbon fibre/polymer matrix composite materials bonded to the structural unit. A consortium of academic and industrial researchers provided much of the data and contributed the chapters to this volume. The research and trial tests were undertaken as part of the United Kingdom's ROBUST project. Strengthening of Reinforced Concrete Structures serves to disseminate the large amount of information that resulted from these studies. As detailed in this book, their results will serve to help generate and formulate design specifications as engineers continue to apply these important techniques to an ever-widening range of applications.

Book Description
Véritable ouvrage de référence, Matériaux composites apporte l'ensemble des concepts théoriques et pratiques nécessaires à la compréhension du comportement mécanique des matériaux et structures composites. Ainsi, il permet d'établir une synthèse de l'analyse du comportement mécanique et de la théorie des plaques stratifiées ou sandwiches, et d'en appliquer les développements à la résolution des problèmes de flexion, de flambement et de vibrations. Composé de cinq parties, ce traité repose sur une approche fondamentale et unifiée aboutissant à une continuité des concepts et des théories. Illustrée de nombreux exercices d'application des concepts introduits, cette cinquième édition entièrement en couleurs a été actualisée et des commentaires ont été ajoutés afin de mettre en évidence la progression du traité. Après une présentation de la constitution puis de la mise en œuvre des matériaux composites, l'ouvrage développe progressivement les outils nécessaires pour modéliser le comportement mécanique des structures en matériaux composites stratifiés et sandwiches. Il aborde ensuite les problèmes de dimensionnement des structures, montrant comment les outils introduits permettent de modéliser le comportement mécanique des structures en matériaux composites. Le contenu et la progression de Matériaux composites ont été conçus avec pour objectifs principaux :- traiter le matériau composite comme un matériau traditionnel ;- intégrer l'apport des techniques numériques dans la résolution des problèmes de dimensionnement des structures ;- aborder les difficultés de manière progressive afin de faciliter l'accès du lecteur aux divers concepts introduits ;- confronter la modélisation avec le comportement réel des matériaux et des structures. Complet et didactique, cet ouvrage s'adresse aux étudiants de 2e et 3e cycles, aux ingénieurs, aux chercheurs ainsi qu'aux techniciens supérieurs [Source : 4e de couv.].

Book Description
Les matériaux composites sont de plus en plus utilisés dans l’industrie grâce à leur rapport performance/masse élevé. Dimensionnement des structures composites présente les critères propres à l’aéronautique, avec en particulier la notion de charges limites et de charges extrêmes. La notion de tolérance aux dommages, propre au domaine aéronautique est ensuite développée, avec notamment son application à la tolérance aux dommages d’impact. Ces notions sont fondamentales pour la compréhension des spécificités du dimensionnement des structures composites aéronautiques. L’objectif de cet ouvrage est de présenter les principes menant au dimensionnement des stratifiés composites largement utilisés dans les structures composites. Après une présentation du principal matériau composite utilisé en aéronautique, la théorie de base des plaques stratifiées ainsi que les critères de rupture associés sont abordés. Deux cas fondamentaux du calcul des structures composites aéronautiques sont traités : le calcul des trous et assemblages ainsi que le calcul du flambage. Le tout est accompagné d’exercices corrigés.

Book Description
17 2 STRESS FIELDS FOR SIMPLE STRUCTURES 2. 1 INTRODUCTION In this chapter the behavior and strength of simple structures made of rein forced or prestressed concrete is investigated with the aid of stress fields. In particular, the webs and flanges of beams, simple walls, brackets, bracing beams and joints of frames are investigated. By this means, the majority of design cases are already covered. In reality, all structural components are three-dimensional. Here, however, components are considered either directly as two-dimensional plate elements (i. e. the plane stress condition with no variation of stress over the thickness of the element) or they are subdivided into several plates. Since two-dimensional structural elements are statically redundant, it is pOSSible for a particular loading to be in equilibrium with many (theoretically an infinite number of) stress states. If the lower bound method of the theory of plasticity is employed, then an admissible stress field or any combination of such stress fields may be selected. In chapter 4 it is shown that this method is suitable for the design of reinforced concrete structures, and the consequence of the choice of the final structural system on the structural behavior is dealt with in detail. The first cases of the use of this method date back to Ritter [6] and Morsch [4], who already at the beginning of the century investigated the resultants of the internal stresses by means of truss models.

Book Description
Strain Hardening Cement Composites, SHCC hereafter, demonstrate excellent mechanical behavior showing tensile strain hardening and multiple fine cracks. This strain hardening behavior improves the durability of concrete structures employing SHCC and the multiple fine cracks enhance structural performance. Reliable tensile performance of SHCC enables us to design structures explicitly accounting for SHCC’s tensile properties. Reinforced SHCC elements (R/SHCC) indicate large energy absorbing performance under large seismic excitation. Against various types of loads, R/SHCC elements can be designed by superimposing re-bar performance and SHCC’s tensile performance. This report focuses on flexural design, shear design, FE modeling and anti-seismic design of R/SHCC elements as well as application examples. Establishing design methods for new materials usually leads to exploring application areas and this trend should be demonstrated by collecting actual application examples of SHCC in structures.
