• Abstract:
  The experimental setup and data are presented for a laboratory experiment conducted to examine realistic wave forcing on a highway bridge ; superstructure. The experiments measure wave conditions along with the resulting forces, pressures, and structural response of a 1:5 scale, ; reinforced concrete model of a typical section of the I-10 Bridge over Escambia Bay, Florida that failed during Hurricane Ivan in 2004. A ; unique feature of this model is its roller and rail system which allowed the specimen to move freely along the axis of wave propagation to ; simulate the dynamic response of the structure. The data are analyzed to study the relative importance of the impulse load versus the sustained ; wave load, the magnitudes of the horizontal to vertical forces, and their time histories to identify the modes of failure. The thesis examines the ; relationship between measured forces and wave momentum flux. The measured forces are also compared to recently published AASHTO ; guidelines. The author evaluates the
