3	Analysis of vertical rectangular abutments of a skewed rigid frame bridge for bending and extension Bottenhofer, Anton J. 19 May 2010 (has links) There has been no attempt made in this paper to compare the results contained herein to any results secured from previous experimental work. The equations presented are complete in themselves. Development of the equations for the abutments has been independent of the angle of skew. Therefore, they may be used with any solution or this type tor a slab of like material and same length knee, skewed at any angle. As a special case, a right rigid-frame bridge could also be analyzed by this method. / Master of Science LD5655.V855 1955.B677 Bridges -- Abutments Short-span bridges
4	Development of a Slab-on-Girder Wood-concrete Composite Highway Bridge Lehan, Andrew Robert 23 July 2012 (has links) This thesis examines the development of a superstructure for a slab-on-girder wood-concrete composite highway bridge. Wood-concrete composite bridges have existed since the 1930's. Historically, they have been limited to spans of less than 10 m. Renewed research interest over the past two decades has shown great potential for longer span capabilities. Through composite action and suitable detailing, improvements in strength, stiffness, and durability can be achieved versus conventional wood bridges. The bridge makes use of a slender ultra-high performance fibre-reinforced concrete (UHPFRC) deck made partially-composite in longitudinal bending with glued-laminated wood girders. Longitudinal external unbonded post-tensioning is utilized to increase span capabilities. Prefabrication using double-T modules minimizes the need for cast-in-place concrete on-site. Durability is realized through the highly impermeable deck slab that protects the girders from moisture. Results show that the system can span up to 30 m while achieving span-to-depth ratios equivalent or better than competing slab-on-girder bridges. bridge composite wood concrete wood-concrete composites composite bridges slab-on-girder bridges post-tensioned bridges glued-laminated timber glulam highway bridge WCC TCC timber-concrete composites advanced materials short span bridges unbonded post-tensioning external post-tensioning double-T match-casting bridge design bridge engineering laminated wood 0543
