Full-Scale Shake Table Cyclic Simple Shear Testing Of Liquefiable Soil, Jasper Stanford Jacobs
Full-Scale Shake Table Cyclic Simple Shear Testing Of Liquefiable Soil, Jasper Stanford Jacobs
Master's Theses
This research consists of full-scale shake table tests to investigate liquefaction of sandy soils. Consideration of the potential and consequences of liquefaction is critical to the performance of any structure built in locations of high seismicity underlain by saturated granular materials as it is the leading cause of damage associated with ground failure. In certain cases the financial losses associated with liquefaction can significantly impact the financial future of an entire region.
Most liquefaction triggering studies are performed in the field where liquefaction has been previously observed, or in tabletop laboratory testing. The study detailed herein is a controlled laboratory …
Scale Model Shake Table Testing Of Shallow Embedded Foundations In Soft Clay, Steven Kuo
Scale Model Shake Table Testing Of Shallow Embedded Foundations In Soft Clay, Steven Kuo
Master's Theses
This research involves shake table testing of 1g scale models that mimic the coupled seismic response of a structure on a shallow mat foundation and foundation soil (known as soil-foundation-structural-interaction or SFSI). In previous research, SFSI effects have been quantified through analytical models, numerical analyses, and limited field data. This research works towards increasing the amount of empirical data through scale model shake table testing. A suite of earthquake time histories is considered in evaluating a nominal 10th scale soil-structure model using a flexible wall barrel on a 1-D shake table. San Francisco Young Bay Mud (YBM) is used …
Scale Model Shake Table Testing Of Underground Structures In Soft Clay, Victor A. Crosariol
Scale Model Shake Table Testing Of Underground Structures In Soft Clay, Victor A. Crosariol
Master's Theses
Underground structures perform an important role in transportation systems in many seismically active regions around the world, but empirical data regarding the seismic behavior of these structures is limited. This research works towards filling that empirical gap through the use of scale model shake table testing. Underground seismic soil-structure interaction (USSSI) effects were investigated for a stiff rectangular tunnel cross-section embedded within soft clay. San Francisco Young Bay Mud was used as a prototype soil for developing a scale model soil mixture consisting of kaolinite, bentonite, class C fly ash, and water. A single cell Bay Area Rapid Transit (BART) …
