The “method of overlap” replaces traditional welding to solve the problem how geosynthetic-encased stone column is limited by frame during site construction, making construction simplified and economical, but its bearing mechanism not clear. Therefore, failure mode was studied through compression test multi-layer under dynamic static loading. research shows that encasement improves modulus late...

The bearing capacity and deformation characteristics of floating stone columns were complicated are not thoroughly understood. In the present study, a series experimental model tests under vertical plate loading was performed. This study investigated influence geogrid encasement on behavior provided valuable insight into load-displacement behavior, bulging deformation, load transfer mechanism, ...

Abstract A parametric study was conducted to investigate the influence of geometric factors on fully encased composite column under eccentric loading about both axes steel section by using ABAQUS software. Thirty-six specimens were assembled 9 different groups considering types length depth ratios (L/D ratios), three eccentricity (e/D and contribution ratios. For validation model, simulations f...

This article presents experimental and numerical studies on the axial compressive behavior of square concrete-encased concrete-filled steel tubular (CECFST) short columns composed a circular inner tube. Tests six full-scale CECFST with tube diameter varying from 320 to 500 mm were carried out study influences sectional thickness CFST their performance. A theoretical model is developed using fib...

This paper reviews the main modeling techniques for stone columns, both ordinary stone columns and geosynthetic-encased stone columns. The paper tries to encompass the more recent advances and recommendations in the topic. Regarding the geometrical model, the main options are the "unit cell", longitudinal gravel trenches in plane strain conditions, cylindrical rings of gravel in axial symmetry ...
