7.2 Earthquake vs. Segmental Retaining Wall (SRW)

Allan Block Passes Full-Scale Earthquake Testing
Full-Scale seismic research confirms the structural capabilities of Allan Block retaining walls under heavy earthquake conditions.
  • How do current SRW design methodologies compare to real life situations?

  • What are the actual forces present within a SRW structure?

  • How would an SRW perform form under the most aggressive circumstances possible – an earthquake?

To answer these questions, Allan Block Corporation, together with Huesker Geosynthetics, sponsored Columbia University on the first full-scale seismic testing ever performed on SRW walls. In the fall of 2002, a series of three tests were conducted on Allan Block walls reinforced with Huesker geogrids at a seismic research facility in Japan.
