Behavior Of Larger-Diameter Strands In The Disturbed Region Of Prestressed Concrete Girders, John Verlin Cabage Jr.
Behavior Of Larger-Diameter Strands In The Disturbed Region Of Prestressed Concrete Girders, John Verlin Cabage Jr.
Doctoral Dissertations
Traditionally, the Tennessee Department of Transportation has been using American Association of State Highway and Transportation Officials – Prestressed/Precast Concrete Institute Bulb Tee (AASHTO-PCI BT) sections for its prestressed concrete bridges. These sections have limited bottom flange widths where the prestressing strands are located. To increase span capacities of these sections, other States have adopted new sections with a wider flange width. Producers in Tennessee have raised concerns about the cost of the new steel forms to accommodate these new sections. As an alternative, this research examines the use of larger diameter strand in conjunction with high-strength concrete and standard …
Determination Of Area Of Fire Origin Through Examination Of Structural Failure And Deformation, Andrew Thomas Tinsley
Determination Of Area Of Fire Origin Through Examination Of Structural Failure And Deformation, Andrew Thomas Tinsley
Doctoral Dissertations
The effects of fire on steel have long been noted and studied. However, a scientific connection between the area of origin for a fire and the amount of steel deformation observed at the scene has never been established. The development and implementation of this type of analysis has the potential to decrease investigation times significantly as the types of structures to which this method would be applicable are typically large, expansive structures. In order to investigate the relationship between structural steel deformations and a fire’s origin, a series of six tests were performed in a smaller size portal frame steel …
