Dr. Petersen has experience in the analysis and design of underground excavations for occupancy, science facilities, transit and mining.
FLAC3D TMis a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers.
This FLAC3D V7.0 training course accommodates new and experienced users. It will be based on examples that attendees will develop and run by themselves to better grasp the mechanics of using FLAC3D V7.0, the key underlying calculation principles and the spectrum of available features. Attendees are encouraged to bring one of their specific cases that may be discussed.
The upcoming 70th annual Highway Geology Symposium will be held in Portland, Oregon, October 21st through October 24th, 2019.
Mr. Stearley, Chief Financial Officer, has 25 years of experience in acquiring and managing businesses as an owner, CEO and CFO, with a concentration on mergers and acquisitions, finance, and human resource development.
As interest in wind power continues to grow, so too has the scale and complexity of wind turbines and their towers, making soil-structure interaction, structural dynamics, and frequency response increasingly important. Numerical simulation is well-suited to capture the behavior of existing and novel designs for these large structures, in a variety of ground conditions – including offshore, to ensure that they satisfy their design criteria.
Itasca’s commercial software FLAC3D is well suited for this type of geotechnical analysis, because it can continuously follow the nonlinear stress-strain response to loading of soils, rock, and concrete. An accurate solution is provided for loads, moments, and deformations at all instances in the loading process. Rather than model the entire tower, the weight and rotational load, representing the tower loading, are applied through a single ring of tower zones.
Itasca has performed analyses to evaluate the effects of site conditions (specifically, the strength and stiffness of the foundation rock) on the foundation rotational stiffness and anchor bolt loads for a range of tower overturning moments for several wind farms, including off-shore.
