A New Approach to Resonant Column Testing
The presentation is about a new approach for performing, analyzing test data, and modeling the shear modulus and damping from Resonant Column Tests. The “New Approach” makes use of the transfer function method of John P. Wolf (Dynamic Soil-Structure Interaction) for modeling the soil specimen as a viscoelastic, distributed mass element. The new solution is simple and easy to implement with a spreadsheet. It provides for accurate determination of shear modulus and damping over a range of frequencies not just the resonant frequency. The analysis of data is done for each applied value of torque and frequency and captures the true nonlinear properties of soil. The method is the basis for the new ASTM Standard D4015-15ε1. Dr. Drnevich will discuss additional uses of the new approach for simulation and modeling.
Vince Drnevich received his B.S. and M.S. degrees in civil engineering from the University of Notre Dame and he completed the Ph.D. degree at the University of Michigan. He held faculty positions
at the University of Kentucky and Purdue University, serving as Chair and Acting Dean at Kentucky and the Head of School at Purdue. His research focuses on the engineering properties of soils, especially as measured by stress wave propagation and electromagnetic wave propagation. Dr. Drnevich has been recognized for both his teaching and research by many national awards from the American Society of Civil Engineers, the American Society for Testing and Materials, and the American Society for Engineering Education.
