SPEAKER: Lawrence E. Keenan AIA, PE, QPSI Both a licensed engineer and a registered architect, Lawrence Keenan brings experience and technical insight to complex structural challenges. He is a Qualified Parking Structure Inspector and has over 30 years’ experience testing, investigating, and
rehabilitating concrete structures. He is a past president of the Connecticut Chapter of ICRI and holds two US Patents for precast concrete structural connections.

OVERVIEW This presentation delves into the fatigue failure mechanisms associated with double-tee connections in precast concrete parking structures. It explores how fatigue failures can be readily identified in the field and provides insights into the practical challenges these failures pose. The discussion includes an examination of code requirements for high-cycle fatigue performance, offering an analysis of recent studies that challenge traditional interpretations established by the precast concrete industry. By offering alternative viewpoints, the presentation aims to foster a deeper understanding of the factors influencing fatigue behavior and the long-term performance of double-tee connections.
