Meet USC
Mon, Jul 28, 2008
Viterbi School of Engineering Undergraduate Admission
Workshops & Infosessions
This half day program is designed for prospective freshmen and family members. Meet USC includes an information session on the University and the Admission process; a student led walking tour of campus and a meeting with us in the Viterbi School. Meet USC is designed to answer all of your questions about USC, the application process and financial aid.Reservations are required for Meet USC. This program occurs twice, once at 9:00 a.m. and again at 1:00 p.m. Please visit http://www.usc.edu/admission/undergraduate/visit/events/meet_usc/ to check availability and make an appointment. Be sure to list an Engineering major as your "intended major" on the webform!

The Earthquake Response of Bridge Foundations to Liquefaction Induced

Sonny Astani Department of Civil and Environmental EngineeringTitle: The Earthquake Response of Bridge Foundations to Liquefaction Induced Lateral Spread Displacement DemandsABSTRACT:The earthquake response of various types of pile foundations supporting a variety of bridge structures to liquefaction induced lateral spread displacement demands is analyzed using the concepts of pile ductility and pile pinning. The soil/pile model uses the stress-strain response of reinforced concrete and steel, incorporating both the axial and lateral loads for structural elements, and p-y curves to represent interface elements to assess the pile response during earthquake induced lateral spread displacement demands.
The analysis approach is incorporated in an improved design methodology using concepts documented in the FHWA "Recommended LRFD Guidelines for the Seismic Design of Highway Bridges".
Case studies of earthquake events, during which lateral spread displacement has caused damage to the bridge pile foundations are revisited to examine the response of these piles using the methodology developed in the research.
Design examples of several bridges supported by various types of pile foundations are also presented and the pile response in terms of plastic hinge development, pile ductility ratio and pile curvature response are studied. It is shown using the methodology developed in this research that given the subsurface conditions, the liquefaction and lateral spread potential and the structural details of the piles at a given
bridge site, one can reasonably assess how close the pile is to acceptable ductility levels in plastic hinge zones. The method also provides a robust approach to screen for the
acceptability of existing bridge pile foundations subject to lateral spread during present day design earthquakes.Location: Kaprielian Hall (KAP) - rielian Hall 209
