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
An analytical study of H15 bridges in Texas has resulted in an improved procedure for issuing overweight truck permits. Single and multiple axle limits, specifically to protest pavements rather than bridges, are assumed. The weight restrictions limit any (and all) axle groups as a function of the gage and tire contact widths. The restrictions were derived to assure that the maximum stress in any bridge member never exceeds the operating level. Only one vehicle is allowed on the bridge at a time but it is assumed to be traveling at a speed such that the full impact allowance is generated.

Book Description
The Michigan Department of Transportation (MDOT) allows trucks that exceed their legal loads to cross bridges if they apply and are approved for a permit. More than 30,000 permits have been processed each year since 2002, providing a vital service to Michigan's economy. However, the permitting system must be robust enough to ensure that the safety of the motoring public is maintained by accounting for overload vehicles without unduly restricting commerce. Currently, structures are placed into Overload Class by checking all service limit states as identified by the 2005 MDOT Bridge Analysis Guide (BAG) with 2009 Interim Updates and the 2010 American Association of State Highway and Transportation Officials (AASHTO) Manual for Bridge Evaluation (MBE) with interims. Vehicles are placed into the Overload Class by comparing the maximum moments of the vehicle for span lengths between 15-ft to 160-ft to the moments produced by the 20 standard overload configurations provided by the BAG. Structures that do not pass an overload class would be marked as restricted and require a specific analysis, increasing the turn-around time for the client and the analysis cost incurred by MDOT. The current software used for the analysis of the structures is a simplified solution that was developed well over 20 years ago when more robust solutions were not feasible. With the capability of modern computing and the availability of bridge software solutions, this research project looks at solutions for updating the bridge analysis as well as the overall overload permit classification process.
