Seismic Performance of Geosynthetic-Reinforced Soil Structures

My works sponsored by the National Science Foundation are included in this page. Other publications are found in my home page

Full-scale shaking table tests (2002)

Tallest of modular block reinforced soil retaining wall tested for earthquake loading
Full-scale (2.8 m high), so don't doubt us about scaling/modeling issues, and real earthquake records

click the picture to see the video of testing

My wish is to go up to 5- or 6-m high wall that represents some of the more critical applications
