Centrifuge
Utilizing experience with silty-sand gained during her PhD, April intends to focus on how to use silty-sands in the centrifuge to produce accountable results to predict the influence of this material on liquefaction; hopefully leading to incorporation into performance-based design.
The main goal of this project is to investigate how the use of compacted granular columns (CGC) may help improve the seismic performance of embankments on potentially liquefiable soils.
The Sandia Senior Design Team were tasked to design a switch that activates at 9g as part of a cubesat subsystem for their senior design project.
This Faculty Early Career Development (CAREER) grant will create a new approach for evaluating the behavior of clusters of buildings on liquefiable ground during earthquakes and pave the way toward designing mitigation measures that improve building performance at a system level.
This project will study the seismic response of temporary and permanent cut-and-cover box structures near mid- to high-rise buildings using a combination of centrifuge testing and numerical simulations.- The Western Transportation Institue has conducted a series of modelling tests of deep patch repairing method used in Highway in our 400 g-ton centrifuge.
- Buried explosion is a complex phenomenon, involving high strain-rate soil dynamics, fluid dynamics, fractures, shocks and multi-scale physics. A comprehensive experimental program using geotechnical centrifuge modeling was conducted in conjunction with computational modeling using finite element, boundary element and discrete element and meshless methods to achieve a new level of scientific understanding of the complex multi-phase phenomena.
