Pier moment-rotation behavior of high performance steel HPS70W I-girders

This dissertation presents a study of the pier moment-rotation behavior of compact and 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 moment-rotation relationship of steel girders with a yield strength exceeding 50 ksi is prohibited. Though, bridge designers are currently allowed to go to plastic moment for I-shape girders having a yield strength of 70 ksi. The second restriction is that the AASHTO LRFD inelastic design methods cannot be used on girders that do not meet the compactness requirements stated in the provisions.
