Designed and constructed in-house, this apparatus is designed to simulate quasi-static Fault Rupture Propagation and Fault Rupture –Soil–Foundation–Structure Interaction. The apparatus has a fixed part and a movable part, which can move downwards or upwards to simulate Normal or Reverse Faulting with a maximum displacement of 200mm in both directions and at a maximum velocity of 5 cm/sec. The angle of Rupture is adjustable from 45 to 90 degrees. The box is of dimensions 3 m x 1.2 m x 0.9 m, having the capability of soil specimens of 100 cm depth, and at its two sides special windows made of Plexiglas are installed to allow observation of soil deformations.
