This study describes how finite element modeling and full scale seismic testing have led to the conclusion that GRS (Geosynthetic Reinforced Soil) abutments are a proven strong and viable solution for bridge support in seismically active areas.
This study compared the finite element model findings to the results of the GRS seismic testing I worked on in 2009 while working at an Army Corps of Engineers research facility in Champaign, Illinois.
This study, in addition to the implementation of GRS technology nationwide, has shown that GRS abutments offer a low-cost and robust alternative to conventional bridge abutments.
Having a thorough understanding of the design and construction of GRS bridge abutments will allow us to provide our clients with the information needed to take a GRS bridge project from start to finish.
During undergraduate coursework I was exposed to ways of using a soils own mass to stabilize itself. I thought some of the concepts were ingenious and I wanted to learn more.
Having a background in carpentry has really helped me be able to visualize the process in which structures are constructed.
