Lateral Behavior Comparison Of Driven And Screw Piles In Stiff Clay, Sophie Moore
Lateral Behavior Comparison Of Driven And Screw Piles In Stiff Clay, Sophie Moore
Architectural Engineering
This study is concerned with the comparison of driven and screw piles when exposed to lateral forces and the effects of gapping on stiffness and displacement. Stiffness contributions were determined from force-displacement profiles, gap depth formation curves, strain profiles, bending moment profiles, and P-Y curves. Driven piles were found to be about twice as stiff as screw piles at lower displacements. At larger displacements, the stiffness of the two pile types start to converge. When the piles are in full contact with the soil, stiffness contribution is derived from both the soil and the pile. When gapping is exhibited, the …
