Download or read book Shrinkage and Creep in Prestressed Concrete written by Perry H. Petersen and published by . This book was released on 1968 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of prestress resulting from creep and shrinkage in concrete was investigated for concrete specime * ns made with Type I portland cement and with Type III portland cement.Forty-nine sets of specimens were fabricated and tested; each set consisted of a prestressed specimen and an otherwise identical companion specimen without reinforcement. The length changes with time were observed at intervals up to an age of 500 days.These observations were made for concretes subjected to different levels of prestress, and for concretes prestressed at different ages.Length changes in nonreinforced companion specimens were also obtained. Thus this study is concerned with elastic deformation occurring at time of stress transfer, shrinkage or swelling, and creep.(Author).

Download or read book Creep and Drying Shrinkage of Lightweight and Normal weight Concretes written by Thomas W. Reichard and published by . This book was released on 1964 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A description is given of a series of tests and test results from an investigation of the mechanical properties of structural-grade lightweight and normal-weight concretes. The major part of the work was planned to obtain comparative values of compressive creep, drying shrinkage, strengths, and moduli of elasticity for concretes made with 24 lightweight and 5 natural, normal-weight aggregates and having the same nominal strength at the time the specimens were placed under load. Data are presented from a total of 76 different concretes which show that there is a wide range in values of the mechanical properties of concretes of the same nominal compressive strength. It is shown that relatively high values of creep and drying shrinkage are not always associated with lightweight concretes and that, in fact, some lightweight concretes have practically the same mechanical properties as some normal-weight concretes. In addition to environmental conditions, the two major factors affecting the creep of concrete appear to be the ratio of the applied stress to the strength at the time of loading, and the aggregate used. Curing conditions, type of cement, mix proportions, and several other variables appear to affect the creep chiefly insofar as they affect the stress-strength ratio. It was observed that the creep at the age of two years can be estimated from the 90-day results with reasonable accuracy. (Author).
Download or read book Concrete and Masonry Movements written by Jeffrey Brooks and published by Butterworth-Heinemann. This book was released on 2014-08-23 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Widely used in the construction of bridges, dams and pavements, concrete and masonry are two of the world’s most utilized construction materials. However, many engineers lack a proper understanding of the methods for predicting and mitigating their movements within a structure. Concrete and Masonry Movements provides practical methods for predicting and preventing movement in concrete and masonry, saving time and money in retrofitting and repair cost. With this book in hand, engineers will discover new prediction models for masonry such as: irreversible moisture expansion of clay bricks, elasticity, creep and shrinkage. In addition, the book provides up-to-date information on the codes of practice. Provides mathematical modelling tools for predicting movement in masonry Up-to-date knowledge of codes of practice methods Clearly explains the factors influencing all types of concrete and masonry movement Fully worked out examples and set problems are included at the end of each chapter
Download or read book The Effect of Temperature on Creep of Concrete written by H. G. Geymayer and published by . This book was released on 1970 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of the literature on the effect of elevated temperatures on the time-dependent volume change due to load (creep) of concrete reveals incomplete and conflicting evidence. Some workers have found a 'creep maximum' at a particular temperature range; others have not encountered this phenomenon. Among those who have found it, there is lack of agreement as to what the range is. All available data have been collected, reduced to comparable form, and analyzed. The analysis has been reviewed in the light of the several theories of the mechanism of concrete creep. It is concluded that the new results on temperature effects on creep do not resolve the conflicts among the various creep theories, but they tend to support the seepage theory more than any other. Many factors affecting creep are found to be influential at elevated temperatures in analogous fashion to their influence at room temperature. These factors include time under load, applied stress, maturity of concrete, and moisture content of concrete. The effect of temperature, at least up to 50 C, is to increase creep by a factor of two or three at 50 C. (Author).

Download or read book Tall buildings written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2014-08-01 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 73: Tall Buildings is the result of a collaboration between the fib and MPA The Concrete Centre (UK). Task Group 1.6 High-rise buildings, within fib Commission 1: Structures, was drawn together with a mandate to write about the experience and know-how pertinent to the development, design and construction of tall concrete buildings. The group’s findings are presented in this state-of the-art report. Tall buildings are a unique challenge to engineers, even to those with extensive experience of low-rise structures. The bulletin explains the critical interfaces with other professionals, for example architects, building services engineers, façade and lift specialists, geotechnical engineers and wind specialists, highlighting how these parties interact with engineers and can influence and guide the development of the structural solution. The key factors in choosing the most appropriate structural system are discussed. The bulletin covers the criteria used to select the most economical structural elements including the foundations, the vertical elements and the floor slabs. Examples of common construction methods are presented and their effects on the structural engineering design are discussed. Tall buildings can undergo significant deformation during their construction and service life. These movements need to be understood by the designer and potentially compensated for in the design and during construction. One of the main particularities of the design of tall buildings is the dominance of the lateral loading from wind and seismic actions. The bulletin provides a discussion of these important topics and sets out the current approach taken by experienced engineers. Designers of tall buildings also need to understand the dynamic behaviour of the structure and confine the motion of the building to within acceptable limits. Approaches to damping and dynamic performance are discussed and guidance provided on the appropriate occupant comfort limits.
Download or read book Creep and Hygrothermal Effects in Concrete Structures written by Zdeněk P. Bažant and published by Springer. This book was released on 2018-01-17 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive treatise covers in detail practical methods of analysis as well as advanced mathematical models for structures highly sensitive to creep and shrinkage. Effective computational algorithms for century-long creep effects in structures, moisture diffusion and high temperature effects are presented. The main design codes and recommendations (including RILEM B3 and B4) are critically compared. Statistical uncertainty of century-long predictions is analyzed and its reduction by extrapolation is discussed, with emphasis on updating based on short-time tests and on long-term measurements on existing structures. Testing methods and the statistics of large randomly collected databases are critically appraised and improvements of predictions of multi-decade relaxation of prestressing steel, cyclic creep in bridges, cracking damage, etc., are demonstrated. Important research directions, such as nanomechanical and probabilistic modeling, are identified, and the need for separating the long-lasting autogenous shrinkage of modern concretes from the creep and drying shrinkage data and introducing it into practical prediction models is emphasized. All the results are derived mathematically and justified as much as possible by extensive test data. The theoretical background in linear viscoelasticity with aging is covered in detail. The didactic style makes the book suitable as a textbook. Everything is properly explained, step by step, with a wealth of application examples as well as simple illustrations of the basic phenomena which could alternate as homeworks or exams. The book is of interest to practicing engineers, researchers, educators and graduate students.
