This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An integral bridge is defined as 'a bridge with bridge abutment that is connected to the bridge deck without any movement joint for expansion or contraction of deck'. When deck joints are not provided, the movements induced in bridge superstructures by secondary stresses must be accommodated by other means. This research is conducted with the aim to analyze specific secondary stresses such as temperature changes, creep and shrinkage and how they affect the integral bridge design through analysis using the Finite Element Method. Application of STAAD.Pro software has been used to model the integral bridge design based on actual data to investigate the effects of movements due to thermal changes and secondary stresses on the design of integral bridge, and the extent of distress ittbringsto the superstructure and substructure.

Available in PDF, EPUB and Kindle. Book excerpt: Integral Bridges (IBs) are joint-less bridges whereby the deck is continuous and monolithic with abutment walls. IBs are outperforming their non-integral counterparts in economy and safety. Their principal advantages are derived from the absence of expansion joints and sliding bearings in the deck, making them the most cost-effective system in terms of construction, maintenance, and longevity. The main purpose of constructing IBs is to prevent the corrosion of structure due to water seepage through joints. The simple and rapid construction provides smooth, uninterrupted deck that is aesthetically pleasing and safer for riding. The single structural unit increases the degree of redundancy enabling higher resistance to extreme events. However, the design of IBs not being an exact science poses certain critical issues. The continuity achieved by this construction results in thermally induced deformations. These in turn introduce a significantly complex and nonlinear soil-structure interaction into the response of abutment walls and piles of the lB. The unknown soil response and its effect on the stresses in the bridge, creates uncertainties in the design. To gain a better understanding of the mechanism of load transfer due to thermal expansion, which is also dependent on the type of the soil adjacent to the abutment walls and piles, a 3D finite element analysis is carried out on a representative IB using state-of-the-art finite element code ABAQUS/Standard 6.5-1. A literature review focusing on past numerical studies of IBs is presented, followed by details of the numerical model developed in this study using the interactive environment ABAQUS/CAE 6.5-1 along with the analysis details. A discussion of results of the analysis of the IB with three different soil conditions, each experiencing three different temperature change scenarios is presented. Conclusions of the study and recommendations for future research wrap up the report. The advancement of knowledge enabled by this research will provide a basis for introduction of new guidelines in Kansas Bridge Design Manual.

This book was released on 2006 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a state-of-the-art reference, an exchange of innovative experience, creative thinking and industry forecasts. This volume presents the proceedings of the fourth international conference in this series based in the Asia Pacific region, in Kuala Lumpur in October 2005 and is applicable to all sectors of the bridge engineering community. BACKGROUND KNOWLEDGE AND FUTURE PERFORMANCE The Institution of Civil Engineers has collaborated with internationally renowned bridge engineers to organise three successful conferences to celebrate the enormous achievements made in the field of bridge engineering in recent years. As a discipline, bridge engineering not only requires knowledge and experience of bridge design and construction techniques but must also deal with increasing challenges posed by the need to maintain the long-term performance of structures throughout an extended service life. In many parts of the world natural phenomena such as seismic events can cause significant damage to force major repairs or reconstruction. Therefore, it is appropriate that the first plenary session of this conference is entitled Engineering for Seismic Performance. READERSHIP This compilation of papers will benefit practising civil and structural engineers in consulting firms and government agencies, bridge contractors, research institutes, universities and colleges. In short, it is of importance to all engineers involved in any aspect of the design, construction and repair, maintenance and refurbishment of bridges.

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.

Download or read book Long Term Behavior of Integral Abutment Bridges written by Robert J. Frosch and published by Joint Transportation Research Program. This book was released on 2011-08-15 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integral abutment (IA) construction has become the preferred method over conventional construction for use with typical highway bridges. However, the use of these structures is limited due to state mandated length and skew limitations. To expand their applicability, studies were implemented to define limitations supported by rational analysis rather than simply engineering judgment. Previous research investigations have resulted in larger length limits and an overall better understanding of these structures. However, questions still remain regarding IA behavior; specifically questions regarding long-term behavior and effects of skew. To better define the behavior of these structures, a study was implemented to specifically investigate the long term behavior of IA bridges. First, a field monitoring program was implemented to observe and understand the in-service behavior of three integral abutment bridges. The results of the field investigation were used to develop and calibrate analytical models that adequately capture the long-term behavior. Second, a single-span, quarter-scale integral abutment bridge was constructed and tested to provide insight on the behavior of highly skewed structures. From the acquired knowledge from both the field and laboratory investigations, a parametric analysis was conducted to characterize the effects of a broad range of parameters on the behavior of integral abutment bridges. This study develops an improved understanding of the overall behavior of IA bridges. Based on the results of this study, modified length and skew limitations for integral abutment bridge are proposed. In addition, modeling recommendations and guidelines have been developed to aid designers and facilitate the increased use of integral abutment bridges.

This book was released on 2023-03-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the introduction of various kinds of advanced composite materials such as carbon fiber-reinforced polymer (CFRP), glass fiber-reinforced polymer (GFRP), aramid fiber-reinforced polymer (AFRP), and basalt fiber-reinforced polymer (BFRP). This book covers the advantages and disadvantages of these advanced composite materials. The primary advantages, such as high specific strength and stiffness, of advance composite materials result in lighter and durable structures. On the other hand, its linear elastic behavior till failure has been highlighted as the main disadvantage for their structural applications. This book also highlights the various forms in which the FRP components are tailored and stacked up to optimize its strength and stiffness to deliver the high-performance structural as well as non-structural components in its real-life application. The various forms in which FRP materials are developed are described such as uni-directional, cross-ply, angle-ply, hybrid, and functionally graded composites. In addition, various forms in which these materials stacked and/ bonded to fabricate the various structural and non-structural components are described. Most importantly, techniques to extract plant-based cellulosic fibers and its application to fabricate the various forms of sustainable composite products are described. In addition, development of nano-particle-enforced cellulosic fibers for sustainable industrial products has also been presented. Furthermore, the use of advanced composites and natural fiber-based composites has been demonstrated for repair, rehabilitation, and retrofitting of deficient structural systems. Moreover, the comprehensive overview of the state-of-the-art research on the test methods for material characterization at room and elevated temperature is presented which will be of high interest to scientists, researchers, students, and engineers working in the fields of composite materials such as FRPs and other forms of composites such as fiber-reinforced concrete (FRC). This book is also helpful for undergraduate, masters, and most importantly Ph.D. research scholars for developing their fundamental understanding on advanced composite materials and their applications in construction as well as industrial sectors.
