Book Synopsis Concrete Dead Load Deflections of Continuous Steel Girder Composite Bridges by : Hani Melhem
Download or read book Concrete Dead Load Deflections of Continuous Steel Girder Composite Bridges written by Hani Melhem and published by . This book was released on 1996 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The changes in the properties of a multi-span continuous steel girder composite bridge during construction can cause final dead load deflections that are quite different from the calculated theoretical values. The casting rate and the sequence of span casting affect the development of concrete stiffness which can significantly affect the final dead load deflections. The study involved two activities: collecting data from the testing of concrete cylinders and laboratory-size beams representative of composite bridge girders and developing a computer program that calculates dead load deflections during construction based on the data from the laboratory testing. The 300 concrete cylinders were tested at ages varying from 2 to 36 hours after pouring to establish stress-strain relations in axial compression. The four composite beams (20 ft (6.1 m) long) with 16 strain gages and 4 deflection gages were tested by applying small incremental loads starting soon after the concrete was poured. Based on these measurements, the change in stiffness of the composite beam was computed and the concrete properties evaluated. The test results helped obtain a relationship that describes the variation of the concrete Young's Modulus with time varying from 2 to 36 hours. Best results were obtained between 4 and 19 hours. The relationship established seems logical and appeared to be consistent in all tests. It was implemented in the computer program and is most valid for ages up to 10 hours. The additional concrete stiffness gained after 10 hours is based on the slope of the curve at 10 hours and a limitation factor that determines the characteristic length of the transition polynomial and which specifies how soon the curve should be asymptotic to the standard value of the 28-days modulus of elasticity. The computer program was verified, however, additional research is needed to test the program more rigorously, to study the effect of concrete confinement and the use of plasticizers, and to compare the results of additional test data with actual field measurements. The effect of the weight of construction equipment should also be studied. Excessive bridge deflection could be avoided with a better understanding of the factors and parameters that affect the deflection.
Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 430 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 Oata Analysis and Synthesis (CINOAS) * 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 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 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 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2016 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many continuous steel bridges constructed prior to the 1970s have floor systems consisting of a non-composite concrete deck over steel beams with no shear connectors. While many of these bridges are still in good condition, the structures may not satisfy current load requirements and thus may need to be strengthened or replaced to avoid load-posting and to maintain structural safety. One potentially economical method of extending the service life of such bridges is to post-install adhesive anchor shear connectors to create composite action between the existing steel beams and concrete deck. This is efficient in regions dominated by positive flexural demands where the concrete deck is in compression. Inelastic moment redistribution away from the interior pier sections can be considered to address strength deficiencies in these regions, which are dominated by negative flexural demands. This dissertation explores this method of strengthening continuous non-composite steel girder bridges. Of particular interest is the “shakedown” behavior of partially composite strengthened girders under large repeated loads requiring moment redistribution. These concepts are commonly referred to as “autostress” design. After conducting preliminary studies on the feasibility of this strengthening method for typical bridges in the state of Texas, an extensive large-scale experimental program was conducted in conjunction with finite element modeling. The results of the testing and modeling are discussed in detail. Design recommendations and a design example are also provided.
