Abstract

The Response of Lightweight Cellular Concrete Tested During Earthquakes

Paula Rodriguez and Nathan Spidell

Advisors: Binod Tiwari Ph.D., P.E., Beena Ajmera, Ph.D.

Abstract

In the research of the behavior of lightweight cellular concrete retaining wall section, experiments were conducted on two different sized sections of lightweight cellular concrete reinforced with a geo-gird at half depth. A shake table was used to test the overall behavior and movement of lightweight cellular concrete during earthquake shaking. After gathering data from accelerometers placed throughout the lightweight cellular concrete retaining wall at different levels, the data was compiled into graphs that demonstrated the overall response of the lightweight cellular concrete retaining walls during earthquakes. Overall, the change in displacement was very small throughout the height of the lightweight cellular concrete retaining wall with little relative changes in displacements between the geo-gird and the top of the retaining wall. This suggests that the lightweight cellular concrete retaining wall section deformed monolithically. In conclusion, the lightweight cellular concrete has the potential to be more adequate than soil when used for engineering purposes.

Keywords: retaining wall, geo-grid, accelerometers
