Avoiding Damage, Distress, and Disappointment in Concrete Structures – 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.
