This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Abstract: Bridge engineers and researchers have been looking for efficient structural forms under the performance-based concept to satisfy various attributes, including serviceability, safety, economy, constructability, durability, etc. Prestressed concrete bridges with corrugated steel webs have emerged as one of the promising bridge forms due to their remarkable advantages such as efficient prestressing of concrete, high buckling strength of steel webs and lightness. In 1986, the first bridge of this type, Cognac Bridge, was built in France. Its successful application and significant advantages over conventional prestressed concrete bridges have prompted researchers and construction companies in various countries to get involved in this new form of composite structure. However, the full-range behaviour of the bridges covering both the service and failure stages is rather complicated, and has not been systematically studied. In view of the different behaviour of components and the large shear deformation of corrugated steel webs with negligible axial stiffness, the assumption that plane sections remain plane is no longer valid and therefore the classical Euler-Bernoulli and Timoshenko beam models may not be applicable. To study the structural behaviour of prestressed concrete bridges with corrugated steel webs, numerical and experimental investigations were carried out. A sandwich beam theory was developed to investigate both the static and dynamic behaviour numerically. In addition, a modified Timoshenko beam model was developed for linearly elastic analysis of static service behaviour, which provides a convenient alternative for design purpose. In the development of numerical models, special emphasis was placed on the modelling of corrugated steel webs, external prestressing tendons, diaphragms, and interaction between web shear deformation and local flange bending. The numerical models were verified by tests. Using the numerical models proposed, the static service behaviour, dynamic properties and long-term behaviour were studied. Some parametric studies were carried out to further explore their structural behaviour. The sectional ductility, deformability and strength were evaluated by nonlinear analysis taking into account the actual stress-strain curves and path-dependence of materials. The numerical results obtained were compared with experimental results for verification. A parametric study was then undertaken to clarify the effects of various parameters. In the design of this type of bridges, both the ultimate load and ductility should be examined, which requires the estimation of full-range structural behaviour. The sandwich beam model was extended for analysis of the full-range behaviour considering geometric and material nonlinearities. With a nonlinear kinematical theory, complete description of the nonlinear interaction between the external tendons and the bridge was obtained. The numerical model proposed was also verified by experiments. The failure mechanisms were studied experimentally and numerically for more accurate evaluation of safety-related attributes such as ultimate load, ductility and deformability. The formation of plastic hinge and its size were also studied thoroughly in view of their importance in the prediction of full-range behaviour. A simplified method to predict the full-range behaviour was also proposed based on the concept o
Book Synopsis Finite Element Bibliography by : Gerard De Vries
Download or read book Finite Element Bibliography written by Gerard De Vries and published by Springer. This book was released on 1976-12 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thjs bibliography had its inception in 1967, when the compilers first attempted a comprehensive cov erage of the finite element literature using both manual and computer-based retrieval. Initially, the data base was stored on a card index, but this was subsequently transferred to punched cards and magnetic tape. Computer processing was adopted at an early stage to derive the three index formats from the data base. Over the subsequent years, several versions of the bibliography were produced, with two of these being made available in a report form to other researchers. From the widespread interest in these documents, it became evident that there was a need for a commercially-available comprehensive bibliography in this area. A major effort was undertaken to revise, update, and extend the data base, resulting in this present volume. The bibliography covers the period 1956-1975 primarily, although some earlier publications of histori cal interest are included. The citations are not restricted to the English language and documents are listed in many languages and from diverse places of origin. All publication formats were accepted, so that references will be found to books, monographs, journal papers and articles, theses, dissertations, reports, surveys, and the like.
Book Synopsis Durability and Fatigue Behavior of CIP Concrete Connections for Accelerated Bridge Construction by : Peng Zhu
Download or read book Durability and Fatigue Behavior of CIP Concrete Connections for Accelerated Bridge Construction written by Peng Zhu and published by . This book was released on 2010 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuous longitudinal and transverse U-bar joint connections between flanges of the decked bulb-Ts (DBTs) or between precast panels for accelerated bridge construction are investigated. The procedure for selecting durable closure pour (CP) materials for the connections is discussed firstly. The accelerated construction is quantified as two categories: overnight cure and 7-day cure of CP materials. Candidate materials are selected first based on literature review as well as tests of compressive strength and flow and workability. Then, performance criteria for selecting durable CP materials for both categories are developed based on durability tests of selected candidate materials. These durability tests include freezing-and-thawing durability, shrinkage, bond, and permeability tests. To investigate the longitudinal U-bar joint details, four pairs of full-scale slabs connected by a U-bar detail with one of the selected CP materials, overnight cure and 7-day cure, were tested. The loading demand necessary in the slab testing is determined based on the maximum forces in the longitudinal joint from an analytical parametric study. Static and fatigue tests under four-point flexural loading and three-point flexural-shear loading were conducted. Test results were evaluated based on flexural capacity, curvature behavior, cracking, deflection and steel strain. The transverse U-bar joint details are investigated to provide negative moment continuity in the multi-span bridges. Four full-scale specimens connected by a U-bar detail with one of the selected CP materials, overnight cure and 7-day cure, were tested. Static and fatigue tests under tension loading were conducted. The loading demand necessary in the beam testing is determined based on the maximum forces in the transverse joint from an analytical study. Test results were evaluated based on tension capacity, cracking, displacement and steel strain. Based on the test results, the developed longitudinal and transverse U-bar joint details are viable connection systems.

Available in PDF, EPUB and Kindle. Book excerpt: Precast/prestressed 'continuous for live load' bridges are used extensively in the United States. The design and analysis of this type of bridge is still based on research conducted during the period 1960-1961. Various studies have been conducted since but, except for minor modifications, the fundamental analysis methods have remained the same. Recent developments in analysis methods and material behavioral research, coupled with long-term experimental and field observations, have raised questions as to the validity of accepted analysis methodology for these bridges. Recent research has determined that the long-term behavior of 'continuous for live load' bridges is not predicted accurately by industry-accepted methods of analysis. Specifically, these analytical models predict an alteration in the distribution of moment in the structure, caused by shrinkage of concrete, which is not confirmed by experimental data. The greatest challenge in modeling 'continuous for live load' is determining a technique for simulating the complex creep and shrinkage behavior of prestressed concrete and the shrinkage and cracking behavior of reinforced concrete. A logical first step would be to model a simple span structure and be sure that the creep, shrinkage and cracking behaviors can be accurately modeled. When this is confirmed, these modeling techniques will be available for use in remodeling 'continuous for live load' bridges. This study attempts to simulate creep due to prestress and dead load in the girders, differential shrinkage between the deck and girder and cracking in the deck of a single span bridge. Finite element analysis was determined to be the most appropriate analytical tool and Abaqus 6.5-1 was seen to have the best combination of tools and user-friendliness. A detailed study of Abaqus documentation and various parametric analyses, determined those facilities tools that could be used to effectively model a prestressed bridge and its long-term characteristics. The results of the simulation concurred with available long-term observations. Evaluation of the simulated history of the structure indicated that cracking of the deck was a possible cause for the discrepancy between field observations and accepted analytical models.
