This book was released on 2012-12-06 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld 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 and broader dissemination. tional publishing house to assure improved service 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 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 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.

Book Synopsis Shear Strength and Shear Fatigue Behavior of Full-scale Prestressed Concrete Box Girders by : Anita K. Buzick
Download or read book Shear Strength and Shear Fatigue Behavior of Full-scale Prestressed Concrete Box Girders written by Anita K. Buzick and published by . This book was released on 1999 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two full-scale prestressed concrete box girders with identical properties were tested. The loads were placed so that shear rather than flexure would govern failure. The first girder was tested to evaluate ultimate shear strength under monotonic loading. The second girder was subjected to one-half million cycles of repeated loading and nine static overloads before its ultimate strength test. The results indicated that the effect of repeated loading on the shear strength of a shear dominated girder is less significant than that of a flexure dominated girder.

Available in PDF, EPUB and Kindle. Book excerpt: Due to frequent accidental damage to prestressed concrete (P/C) bridges caused by impact from overheight vehicles, a project was initiated to evaluate the strength and load distribution characteristics of damaged P/C bridges. A comprehensive literature review was conducted. It was concluded that only a few references pertain to the assessment and repair of damaged P/C beams. No reference was found that involves testing of a damaged bridge(s) as well as the damaged beams following their removal. Structural testing of 2 damaged bridges was conducted in the field.

Book Synopsis Fatigue Behavior of Post-installed Shear Connectors Used to Strengthen Continuous Non-composite Steel Bridge Girders by : Amir Reza Ghiami Azad

This book was released on 2016 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many older bridges in Texas are constructed with floor systems consisting of a concrete slab over steel girders. A potentially economical means of strengthening these floor systems is to connect the existing concrete slab and steel girders using post-installed shear connectors to change the behavior of the beam from non-composite to partially-composite. Since fatigue is one of the main concerns in designing bridges, investigating the fatigue properties of these post-installed shear connectors becomes crucial. Results from direct-shear testing show that post-installed shear connectors have a better fatigue life compared to conventional welded shear studs. However, based on currently available data from direct-shear tests, fatigue life of post-installed shear connectors is still inadequate for economical retrofit in some cases. Furthermore, it is unclear if direct-shear tests provide an appropriate means of evaluating fatigue performance. The objective of this dissertation is to develop new and more accurate approaches for evaluating the fatigue characteristics of post-installed shear connectors. This objective is addressed through large-scale beam fatigue tests and computational studies. The focus of the work is on evaluating fatigue life of shear connectors based on both slip and stress demands.
Book Synopsis Fatigue and Shear Behavior of High Performance Concrete Bulb-tee Girders by : Robert N. Bruce
Download or read book Fatigue and Shear Behavior of High Performance Concrete Bulb-tee Girders written by Robert N. Bruce and published by . This book was released on 2003 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three 96-ft (29.3-m) long, 72-in. (1.83-m) deep, precast, pretensioned bulb-tee girders were tested to evaluate behavior under flexural fatigue and static shear loadings. The three girders had a design concrete compressive strength of 10,000 psi (69.0 MPa) and incorporated 0.6-in. (15.2-mm) diameter, Grade 270, low relaxation prestressing strands. The shear reinforcement quantities at the ends of each girder were selected to evaluate the applicability of the shear strength design provisions of the AASHTO Standard Specifications for Highway Bridges and the AASHTO LRFD Bridge Design Specifications. Shear reinforcement consisted of conventional bars or deformed welded wire reinforcement. The three prestressed concrete girders were produced in a commercial plant. Prior to testing, a 10-ft (3.05-m) wide reinforced concrete deck slab was added to each girder. After completion of fatigue testing, each girder was cut in half and the six girder ends tested to evaluate static shear strength.

Book Synopsis Investigation of Shear Distribution Factors in Prestressed Concrete Girder Bridges by : Benjamin Z. Dymond
Download or read book Investigation of Shear Distribution Factors in Prestressed Concrete Girder Bridges written by Benjamin Z. Dymond and published by . This book was released on 2016 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: As shear requirements for prestressed concrete girders have changed, some structures designed using older specifications do not rate well with current methods. However, signs of shear distress have not been observed in these bridge girders and they are often deemed to be in good condition. The primary objective of this research program was to investigate the accuracy of existing shear distribution factors, which are used to estimate bridge system live load effects on individual girders, and provide recommendations on shear distribution to be used in Minnesota with four components: a full-scale laboratory bridge subjected to elastic and inelastic behavior, field testing of bridges, a numerical parametric study, and integration of results to develop a screening tool to determine which structures benefitted from refined analysis. Laboratory bridge inelastic testing indicated shear force redistribution after cracking and before ultimate failure. Use of elastic distribution factors is conservative for shear distribution at ultimate capacity. Elastic laboratory testing was used to validate the finite element modeling technique and study the behavior of a barrier and end diaphragm, which affected shear distribution; ignoring their effects was conservative. Parametric study results indicated that a ratio of longitudinal stiffness to transverse stiffness could be used as a screening tool. If the stiffness ratio was less than 1.5, shear demand from a simple, conservative grillage analysis may be more accurate than shear demand from AASHTO distribution factor methods. Grillage analysis shear demand results due to permit trucks may also be more accurate, regardless of the screening tool ratio.
