... significant role in restraining the lateral displacement of the wall during the excavation process and possibly at its ultimate limit state as well. The outcome of this investigation is that lateral bending has significant effects as the reinforced soil approaches failure and analytical procedures developed...

... horizontal load is applied to each individual front tire through a chain linked to a thread rod. The load application system ensures no displacements restraints to each individual tire placed in the front row. To evaluate the tire geometry influence, some tests were performed with entire tires and cut tires...

... supported by the steel pile group in soft ground. The test construction employed two kinds of abutment, named Type-A without pre-load and Type-B with small-scale pre-load to investigate the effect of pre-load. Furthermore, the increase of displacement and stress in the pile due to an earthquake was...
