Push-over Test Apparatus (Reaction Wall)

Also designed and constructed in-house, the apparatus is used for monotonic and slow-cyclic pushover testing of soil-foundation- structure systems. The apparatus is equipped with an electronically controlled screw-jack actuator, having a capacity of 1 ton and producing a stroke of +/- 500 mm, with a maximum velocity of 50 mm/sec. The apparatus is rigidly attached to a reaction wall, while its free end is connected to the model through a linear guideway and a hinged connection in series, allowing the system to freely settle, slide, and rotate as horizontal displacement is imposed.
