Avoiding Damage, Distress, and Disappointment in Concrete Structures
Date: February 18, 2021
Time: 8:00 – 9:00 am CST
Presenter: Michael Lee, (Principal - Wiss, Janney, Elstner Associates, Inc.)
Credits: 1 PDH and/or 1 AIA CES LU/HSW (AIA Course #MCC021821)

Description: This presentation reviews failures, damages, and other incidences of poor performance in concrete structures that have served to shape today's building codes and the standard of care for the profession. Examples range from well-documented, high-profile collapses to lesser known but similarly influential structural and serviceability problems. Case histories will include discussion of excessive cracking, the cause of such distress, and mitigation measures. The case histories will illustrate how small details can often mean the difference between success and disappointment; and how codes have evolved to reduce the risk of future failures.
- Attendees will understand how failures, damages, and other incidences of poor performance in concrete structures have served to shape today's building codes and the standard of care for the profession.
- Attendees will be able to identify examples of well-documented, high-profile collapses and lesser known but similarly influential structural and serviceability problems.
- Attendees will understand some causes of excessive cracking in concrete.
- Attendees will comprehend how to mitigate excessive cracking in concrete.
Michael Lee investigates hundreds of distressed buildings, parking garages, and other structures. The distressed conditions have involved concrete deterioration, water leakage, collapse, construction deviations, and facade deterioration. Mr. Lee uses structural analyses, load tests, nondestructive testing, and laboratory studies to determine the cause and significance of the distress. He also develops drawings and specifications to repair the affected structures.
Prior to joining WJE, Mr. Lee worked at HDR (formerly W.E. Simpson) and Campbell & Associates, where he acquired fourteen years of structural design experience. At these firms, he was responsible for the analysis, design, or construction administration for over five million square feet of office, medical, parking, and educational facilities. His experience encompasses precast, post-tensioned, two-way, composite, and long-span structural systems. In addition, Mr. Lee has investigated existing structures and designed modifications, as required, by changes in occupancy and loading.
