Pier moment-rotation behavior of high performance steel HPS70W I-girders
… noncompact high performance steel HPS70W I-shape girders in the context of examining two restrictions for inelastic design of steel bridge girders in the current edition of the AASHTO LRFD bridge code (AASHTO, 1998 and interim 2001). The first restriction is that inelastic design involving the …

Carbon Fiber Reinforced Polymer Repairs of Impact-Damaged Prestressed I-Girders
… capacity of impact-damaged prestressed concrete girders. The number of severed prestressing strands and the amount of CFRP repair material applied are varied to create a large repair matrix. The ultimate moment capacity was calculated using the program XTRACT. Capacities were also evaluated using …

Evaluation of the ductility of composite steel I-girders in positive bending
Current AASHTO bridge specifications limit the allowable maximum strength of simple spans and positive bending regions with adjacent compact pier sections to a value between the full plastic moment and the hypothetical yield moment of the cross section. The equation used for this strength …

Seismic performance of an I-girder to inverted-T bent cap bridge connection
… that the connection between the precast I-girders and the inverted-T bent cap will degrade in a seismic event and shall therefore be designed as a pinned connection, making the precast girder option for seismic bridges inefficient. A prototype I-girder to inverted-T bent cap bridge and a …

Shear strengthening of reinforced concrete beams with bi-directional carbon fiber reinforced polymer (CFRP) strips and CFRP anchors
… to the concrete. Previous tests on prestressed I-girders strengthened with uni-directional and bi-directional CFRP strips showed that bi-directional CFRP application resulted in significant shear strength gain in comparison to a uni-directional application. The objective of this thesis is to …

Effect of Thermal Loading on the Performance of Horizontally Curved I-Girder Bridges
… of a section consisting of two curved steel I-girders connected with cross frames. The major focus of this research is a case study on the response of the Buffalo Creek Bridge, located in Logan County, West Virginia, to changing thermal conditions prior to any in-service loading. Two detailed …

Transfer and Development Lengths of Steel Strands in Full-Scale Prestressed Self-Consolidating Concrete Bridge Girders
… behavior of steel strands in prestressed bridge girders. In the first phase, 56 pullout tests were conducted to compare the performance of seven-wire strands embedded in SCC and conventionally-consolidated concrete blocks. In the second phase, transfer lengths of prestressing strands in two SCC …

Self-Compacting Concrete for Prestressed Bridge Girders
… for the construction of precast prestressed SCC girders in the State of Minnesota. The primary objective of the research was to determine both short-term and long-term properties of SCC bridge girders, evaluate the applicability and accuracy of available test procedures, design equations, and …
