Book Description
This report describes the research program conducted on high-strength bolts and connectors that have been over-tightened. Direct-tension indicators (DTI) may be specified for use on high-strength bolts to verify that the bolts have been sufficiently tensioned. This research was initiated at the request of the Idaho Transportation Department in order to resolve questions concerning the use of bolts installed with DTI which had been tightened to zero gap readings.

Book Description
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.

Book Description
The current means and methods of verifying that high-strength bolts have been properly tightened are very laborious and time consuming. In some cases, the techniques require special equipment and, in other cases, the verification itself may be somewhat subjective. While some commercially available verification techniques do exist, these options still have some limitations and might be considered costly options. The main objectives of this project were to explore high-strength bolt-tightening and verification techniques and to investigate the feasibility of developing and implementing new alternatives. A literature search and a survey of state departments of transportation (DOTs) were conducted to collect information on various bolt-tightening techniques such that an understanding of available and under-development techniques could be obtained. During the literature review, the requirements for materials, inspection, and installation methods outlined in the Research Council on Structural Connections specification were also reviewed and summarized. To guide the search for finding new alternatives and technology development, a working group meeting was held at the Iowa State University Institute for Transportation October 12, 2015. During the meeting, topics central to the research were discussed with Iowa DOT engineers and other professionals who have relevant experiences.

Book Description
Due to significant economic growth in the last few decades, increasing traffic loads impose tremendous demand on bridge structures. This, coupled with ongoing deterioration of bridges, introduces a unique challenge to bridge engineers in maintaining service of these infrastructure assets without disruption to vital economic and social activities. This requires innovative solutions and optimized methodologies to achieve safe and efficient operation of bridge structures. Bridge engineering practitioners, researchers, owners, and contractors from all over the world presented on modern techniques in design, inspection, monitoring and rehabilitation of bridge structures, at the Sixth New York City Bridge Conference held New York City on July 25-26, 2011. This book contains a select number of papers presented at the conference. This group of papers provides a state-of-the-art in bridge engineering and is of interest to any reader in the field.
