Shaking tables with lateral displacement

Shaking tables with lateral displacement

The shake table test - was performed under a centrifuge acceleration of 15g. The large-scale test results showed that the lateral displacement of the sheet-pile is increased by about 5seconds during the shaking, while the sheet-pile showed significant lateral spreading for about 200 seconds after the shakingentrifuge stud. y generally The c
