Wire Mesh Tension Testing

March 13, 2020

In summer 2019, former masters student David Kyle Anderson conducted 28 tension tests on 5 different types of wire mesh used for soil stabilization at CIEST.


Evaluation of Hazard-Resistant Pipelines

Sept. 27, 2019

The first in a series of testing programs at CU Boulder CIEST investigating performance of critical lifeline systems under extreme loading conditions.


Seismic Evaluation of HSS Column Splices

June 28, 2019

Project included development of a bi-directional loading system to apply simultaneous axial and lateral loading to 6 in. diameter columns and splice connections. Nearly 60 full-scale tests were conducted to support evaluation of a new structural building system for seismic applications. Accredited testing performed to ISO/IEC 17025 standard following protocols provided by FEMA 461.


Liquefaction of Silty Sands

Feb. 18, 2019

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.
