This book was released on 2012-12-06 with total page 427 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 dis semination 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 concerned if the printing and distribution of the volumes were handled by an international 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 Corporation 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 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to develop finite element computer programs to calculate stresses and deflections in rigid multicomponent pavements with cracks and joints, as well as in the supporting subgrade soil, subjected to loads and temperature warping. This report is presented as a user's manual for the WESLAYER program, which deals with pavements on layered elastic solids. The pavement can have full or partial loss of subgrade support over designated regions of the pavements. Multiple-wheel loads can be used in the computation and the number of wheels is not limited. Because of large storage space needed and long computer time required to obtain solutions, the program is limited to only a two-slab system. The nature of the computer program and its program logic are first delineated, followed by a general discussion on the efficient and correct use of the program. An input guide to the computer program is presented with a detailed explanation for each input variable. Example problems with input data and output printouts are presented. (Author).

This book was released on 2004 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the effect of dowel bar shape and spacing on the Load Transfer Efficiency of transverse joints in Portland Cement Concrete Pavements. Three different dowel bar sizes, were utilized for this research: a 1.5-inch round dowel bar, an elliptical dowel bar with axes 1.98 and 1.33 inches, and a second elliptical dowel bar with axes of 1.66 and 1.13 inches. Three spacings were investigated with the dowel bar shape, which included 12 inches, 15 inches and 18 inches. The research was accomplished by comparing finite element analyses of the nine shape and spacing combinations with the data collected from construction along Ia. 330. A portion of the highway was constructed using steel dowels of the three sizes described above. Deflection data was collected by the Iowa Department of Transportation using a Falling Weight Deflectometer. Also integrated into the study is the effect the dowel bar shape and spacing has on the reactions imposed on the embedded dowel bars from the applied loads on the pavement surface. A macro was developed using finite element analysis to record the deflected shape, bending moments, shear force, stresses and elastic strains experienced by the dowel bar. Theoretical developments by S. Timoshenko, B. Friberg, and Tabatabaie were also included in this research for comparisons with the finite element analyses.

This book was released on 1979 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers the development of rigid pavement joint models, the theoretical evaluation of joint systems and the results and conclusions reached from these studies. This is Volume II of a three volume series on the design and construction of longitudinal joint systems in slip-formed concrete pavements. Volume I - Literature Survey and Field Inspection - dated January 1979, was issued earlier. Volume II - User's Manual is now being printed. This report emphasizes the theoretical evaluation of joint systems. Although the study was primarily for the analysis of longitudinal joint systems for use with slip-formed pavements, the data is applicable to the analysis/design of other types of joints in rigid pavements. The study has been divided into 4 phases. Part 1, Extensive Literature Review; Part 2, Development of Rational Structural Analysis Methods; Part 3, The Finite Element Computer Model is compared with other theoretical Methods; Part 4 Studies Were Made to Define the Interaction of Joint Components and How They Affect the Stresses and Deflections of the Pavements. Cost data are given for the various alternate systems considered. (Author).

Book Synopsis Numerical Investigation of the Effects of Shrinkage and Thermal Loading on the Behaviour of Misaligned Dowels in Jointed Concrete Pavement by : Cyril Levy

This book was released on 2010 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dowel bars in jointed plain concrete pavement (JPCP) have the important function of transferring wheel loads from one slab to the other, hence ensuring that the deflections on each side of the joint are kept almost equal. As well, the dowels should not impede the concrete pavement movements due to environmental effects (temperature and moisture). Dowel bar misalignment, attributed to deficient construction practice, is a major cause of joint distress or faulting by inhibiting the free movement of the slab at the joint. To prevent these issues, tolerance guidelines on misalignment levels are implemented by transportation agencies. Review of previous studies indicate that many researchers analysed the effects of dowel bar misalignment on pavement behaviour using a pull-out test, that is a forcebased opening of the joint. These approaches neglect that joints movements in the field are strain-governed by non-linear temperature and shrinkage actions, leading to combined axial movements and curling of the slab. In this study, the fundamental dowel bar behaviour under shrinkage and thermal loading was determined through detailed 3D finite element modelling (3D-FEM). To that end, models of dowel jointed concrete slabs were developed and subjected to realistic non-linear profiles of shrinkage and thermal strains. Studies were carried out on a single-bar model, taking into account bar-concrete friction and plastic concrete behaviour. The parameters that were investigated included different configurations and levels of bar misalignment and different friction coefficients between the steel and the concrete, simulating the use of bond-breakers. To interpret the results from the numerical analysis, criteria for concrete damage were developed and used in parallel with measures of joint load transfer efficiency; these were obtained by examining the response of the slab under a Falling Weight Deflectometer (FWD) drop at the joint. The results were verified by comparing the outputs of a model consisting of one half of a slab to published data. The analysis of the models revealead that none of the models showed signs of significant damage after the application of shrinkage and two thermal cycles. Analyses with up to ten thermal cycles did not indicate progressive accumulation of damage, suggesting that for the chosen parameters there is no the concrete around the dowel bar will not fail. Models with bars placed higher in the slab and bars with angular misalignment exhibited more damage than the non-misaligned models without reaching the damage criteria used in this study. The models did not exhibit the amount of damage reported in the studies on dowel bar misalignment having used pull-out tests. It was found that no significant difference existed between uncoated and coated dowel bars models results with regards to concrete damage at the joint. However, a high coefficient of friction between the dowel and the concrete, simulating dowel bar corrosion, proved to be the most detrimental to joint integrity. All of the models performed very well with respect to joint load transfer efficiency, suggesting that the plastic strains in the concrete around the dowel did not have a significant impact on joint performance for the realistic range of parameters investigated.

This book was released on 2007 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: According to the Federal Highway Administration (FHWA Highway Statistics, 2004), almost $900 billion was spent on the maintenance and reconstruction of the U.S. highway system during the ten year period from 1995 to 2004. It is clear that improving the pavement analysis and design methods could result in annual savings in the millions and possibly billions of dollars. The response models based on multi-layer elastic theory and displacement-based finite element methods are currently the most widely used and both are adopted as the structural response models in the recently released Mechanistic Empirical Pavement Design Guide (MEPDG). These models are capable of predicting global responses such as surface deflections but are not able to accurately predict the transverse stress distribution which is imperative to model the realistic behavior of in-service pavement systems and prevent premature failure caused by pavement layer debonding. A stress-based model developed at Ohio State for composite laminates has shown the capability of accurately predicting the dynamic stresses at layer boundaries while retaining the ability to determine displacement behavior. In this study, the stress-based multi-layer plate theory was extended to layered pavement systems as an alternative to existing pavement response models for the analysis and design of pavements. The proposed model was verified by comparing its solutions to existing analytical, numerical solutions, and experimental results. Good agreement was obtained in the predicted surface deflection response from existing analytical, numerical solutions and the stress-based model. It was shown that the current stress-based model can overcome the limitation of displacement-based method and predicted more accurate and realistic transverse stress at the pavement layer interfaces. Overall, a reasonably close prediction was obtained between calculated and measured responses from the two full-scale pavement experimental studies. Moreover, a sensitivity study was carried out in order to obtain a better understanding of the different factors that affect the interface transverse stresses at the interface between surface layer and base layer. Finally, the stress-based model was used to analyze thin concrete overlay rehabilitation of rigid and flexible pavements.
