Pullout And Tensile Behavior Of Crimped Steel Reinforcement For Mechanically Stabilized Earth (Mse) Walls, Oscar Ernesto Suncar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many research studies made on hundreds of MSE walls have shown that in order to get lower values of lateral earth pressure coefficients from an active condition on the backfill soil, thus lower exerted loads and stresses on the reinforcement, the wall needs to yield. This is typical of extensible polymer-based wall systems, such as geosynthetics. Steel systems, on the other hand, are very rigid and do not allow enough deformation on the wall to generate the active condition.

For this research, steel reinforcement for MSE walls that behaves similar to geosynthetics was developed. This was done by using crimps …
