Measuring Liquefied Residual Strength Using Full-Scale Shake Table Cyclic Simple Shear Tests, Taylor R. Honnette
Measuring Liquefied Residual Strength Using Full-Scale Shake Table Cyclic Simple Shear Tests, Taylor R. Honnette
Master's Theses
This research consists of full-scale cyclic shake table tests to investigate liquefied residual strength of #2/16 Monterey Sand. A simple shear testing apparatus was mounted to a full-scale one-dimensional shake table to mimic a confined layer of saturated sand subjected to strong ground motions. Testing was performed at the Parson’s Geotechnical and Earthquake Laboratory at California Polytechnic State University, San Luis Obispo. T-bar penetrometer pullout tests were used to measure residual strength of the liquefied soil during cyclic testing. Cone Penetration Testing (CPT) was performed on the soil specimen throughout testing to relate the laboratory specimen to field index test …
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 …
