Managing Engineer, Exponent
Dr. Vytiniotis is a managing engineer in Exponent’s Civil practice, a member of the Geo-Institute’s Deep Foundation and Computation Geotechnics committees and a regional director for the Society of Construction Law – North America. He has background in structural and geotechnical engineering, geotechnical earthquake engineering, and numerical analysis. Dr. Vytiniotis has worked on numerous projects in more than 20 states and multiple countries, assisting project owners, law firms, insurance companies and developers. His analyses consist of assessing soil improvement, soil-structure interaction, dam safety, causation of MSE wall failures, effects of adjacent construction (such as vibrations or pile driving), soil heave or settlements, pipeline installation, water intrusion, and backfill quality. He is experienced in evaluating slope stability, performing mechanical and flow-through-porous media finite element analyses and soil-structure interaction using various software. Additionally, Dr. Vytiniotis has performed research on the seismic response of pile-supported wharves, seismic slope stability, the effectiveness of prefabricated vertical drains (earthquake drains) and soil densification in reducing liquefaction risk, the effect of gravel drains in amplifying seismic accelerations, and numerical simulations of centrifuge experiments. In the past, Dr. Vytiniotis gained international experience in Greece and Switzerland, and was appointed lecturer at MIT.

Course Title: Deep Dive into Geo-Structural Failures and Lessons Learned
Delivery Method: Live Online
Course Description: This course examines the causes and effects of geo-structural failures, including reinforced earth wall deformations, failures of pipes backfilled with CLSM, soil effects in LNG tanks, lateral movements of a retaining wall due to pile driving, and underground detention systems.
Learning Objective 1:
Learners will be able to define what constitutes a geo-structural problem or failure involving a built structure.
Learning Objective 2:
Learners will be able to discuss problems brought on by deformations of a reinforced earth wall.
Learning Objective 3:
Learners will be able to identify the potential consequences of a failure in a pipe backfilled with controlled low strength material (CLSM).
Learning Objective 4:
Learners will be able to explain how lateral movements of a retaining wall can occur due to pile driving and how those movements can impact the structure.
LUs: 2.0 LU Type: LU|HSWs.
Prerequisites: Familiarity with site evaluation and development
