Abstract: The axial loading test on a geogrid-encased stone column has been simulated using 3D numerical model in the proposed study. The stone column was modeled using the discrete element method (DEM), and the geogrid was modeled ...

Abstract: This study numerically investigates the failure processes of recycled aggregate concrete (RAC) and natural aggregate concrete (NAC). A two-dimensional simulation based on a discrete-element method (DEM) is conducted with ...

Abstract: The discrete element method–finite difference method (DEM--FDM) numerical simulation was conducted to investigate the failure process and the bearing mechanism of the single stone column in soft soil beneath rigid loading. ...

Abstract: Compared with isolated stone columns, a group of stone columns exhibits a much more complicated failure mechanism because of the complicated interactions between the respective columns and the surrounding soil under various ...

Abstract: One of the most important components of box beam bridges is the shear key that connects the box beams together. The shear keys in box beam bridges often fail at the interface. In recent years, ultrahigh-performance concrete ...
