Control of Cracking in Reinforced Concrete Structures: Research Project CEOS.fr (Civil Engineering and Geomechanics)

The purpose of this book is to provide guidelines which can extend the existing standards and codes to cover these types of special works, especially those which are massive in nature, taking account of their specific behaviour in terms of cracking and shrinkage together with other important properties such as water/air leak tightness.;CEOS.fr Project Presentation -- Hydration Effects of Concrete at an Early Age and the Scale Effect -- Cracking of Ties -- Cracking of Beams Under Mechanical Flexural Loading -- Cracking in Walls -- Minimum Reinforcement of Thick Concrete Elements -- Shrinkage, Creep and Other Concrete Properties -- Cracking of Beams and Walls Subject to Restrained Deformations at SLS -- Effects of Various Phenomena in Combination -- Numerical Modeling: a Methodological Approach -- Recommendations for the use of Measurements on Mock-up Test Facilities and Structures. This book presents new guidelines for the control of cracking in massive reinforced and prestressed concrete structures. Understanding this behavior during construction allows engineers to ensure properties such as durability, reliability, and water- and air-tightness throughout a structure's lifetime. Based on the findings of the French national CEOS.fr project, the authors extend existing engineering standards and codes to advance the measurement and prediction of cracking patterns. Various behaviors of concrete under load are explored within the chapters of the book. These include cracking of ties, beams and in walls, and the simulation and evaluation of cracking, shrinkage and creep. The authors propose new engineering rules for crack width and space assessment of cracking patterns, and provide recommendations for measurement devices and protocols. Intended as a reference for design and civil engineers working on construction projects, as well as to aid further work in the research community, applied examples are provided at the end of each chapter in the form of expanded measurement methods, calculations and commentary on models.
