Seismic Analysis Of Integral Abutment Bridges Considering Soil Structure Interaction, Reza Vasheghani Farahani
Seismic Analysis Of Integral Abutment Bridges Considering Soil Structure Interaction, Reza Vasheghani Farahani
Masters Theses
Integral abutment bridges are jointless bridges in which the deck is continuous and connected monolithically with the abutment walls supported typically by a single row of piles. This thesis focuses on the effects of two major parameters on the seismic behavior of an integral abutment bridge in Tennessee by considering soil-structure interaction around the piles and in back of the abutments: (1) clay stiffness (medium vs. hard) around the piles, and (2) level of sand compaction (loose vs. dense) of the abutment wall backfilling. Modal and nonlinear time history analyses are performed on a three dimensional detailed bridge model using …
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) …
