SORM-Based Probabilistic Analysis of Pile in 2-Layer under Lateral Spread Soil

September 8, 2021 Engineering 0

Because of its significant effect and substantial destructive character during and after seismic events, lateral ground spreading has gotten a lot of attention. This paper explains how to forecast pile failure due to lateral spread quickly. The suggested approach combines the limit equilibrium method (LEM) and the second-order dependability method (SORM). A limit equilibrium-based finite element model is coupled with (SORM) using the response surface method in this technique (RSM). The soil is represented by a 3D solid elastoplastic element (Drucker-Prager failure criterion) in the finite element model, whereas the pile is represented by an elastic 3D beam element. Through numerical examples, Monte Carlo Simulation (MCS) is used to validate the proposed method. There are operational and structural limit states to consider. The soil pressure and pile radius are revealed to be the most sensitive factors in the case study.
