Proposed Dynamic Soil Pressure Diagram On Rigid Walls.
Using finite element nonlinear analysis, the dynamic soil pressure on perimeter retainingwalls of structures is investigated. Nonlinear Drucker Prager failure criterion is used to model the soilbehavior in the near field. The far field soil and the middle structure are assumed to behave as linearelastic materials. The soil-wall interface behavior is modeled incorporating nonlinear interfaceelem...
متن کاملCollision Prediction Among Rigid and Articulated Obstacles with Unknown Motion
Collision prediction is a fundamental operation for planning motion in dynamic environment. Existing methods usually exploit complex behavior models or use dynamic constraints in collision prediction. However, these methods all assume simple geometry, such as disc, which significantly limit their applicability. This paper proposes a new approach that advances collision prediction beyond disc ro...
متن کاملSeismic Active Earth Pressure of Narrow Geosynthetic-Reinforced Backfill on Rigid Facing
In the narrow geosynthetic-reinforced retaining walls a stable rear wall exists in a short distance and so there is no enough space to extend appropriate length of reinforcements. In this case, the probability of overturning of retaining wall increases especially when subjected to earthquake loading. To increase the stability of the wall, reinforcements may be connected to the stable rear surfa...
متن کاملDistribution of lateral active earth pressure on a rigid retaining wall under various motion modes
The design of retaining walls depends on the magnitude of active pressure exerted from the backfill. Therefore, estimating the scale of this pressure is a fundamental factor in the design. In this study, to assess the active earth pressure, a rigid retaining wall was built capable of translating and/or rotating with adjustable speed. Further, several physical tests were conducte...
