Project Details

Title:Seismic Performance of Highway Embankments
Principal Investigators:Hussam Mahmoud
University:Colorado State University
Grant #:DTRT12-G-UTC08 (SAFETEA-LU Extension)
Project #:MPC-383
RH Display ID:13090
Keywords:bridges, disasters and emergency operations, earthquake resistant design, embankments, risk assessment, seismicity


The objective of this study is to develop an approach for assessing the performance of embankments under seismic loads. The project seeks to highlight the various observed failures in highway embankments and the importance of including their behavior in post-earthquake recovery and relief missions. Finite element models of highway embankments will be developed and used to conduct nonlinear dynamic time-history analysis. The result of the analysis will be compared against specific performance levels. A methodology will be proposed for estimating the potential and degree of damage to highway embankments, which can be used by decision makers in determining if a particular route can be utilized for post-earthquake relief and recovery missions.
