Research
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.
Shideh Dashti, assistant professor of geotechnical engineering and geomechanics at CU-Boulder, co-led a scientific reconnaissance team mobilized by the Geotechnical Extreme Events Reconnaissance (GEER) Association to travel to Kumamoto-shi, Japan,
 Experimental Performance Assessment of Nearly Full-Scale Reinforced Concrete Columns with Partially Debonded Longitudinal Reinforcement- 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.
