CONCRETEFiX 5.13 – TMH7 Earthquake Loading: Practical Insights on Plastic Hinge Confinement for Bridge Columns
Balancing Safety and Cost for Resilient Bridge Design in Low-Seismic Regions
By Wandie Olivier, Associate Bridge Engineer, AECOM
Earthquake resilience in bridge design is critical for ensuring safety and functionality during seismic events. This presentation explores the TMH7 guidelines for seismic design, with a specific focus on confinement in the plastic hinge regions of bridge columns—a key factor in ductility and energy dissipation. We will discuss the principles behind confinement detailing, review practical design considerations, and highlight common challenges encountered in applying TMH7 provisions. Through examples and insights from real-world projects, attendees will gain a deeper understanding of how proper confinement strategies enhance structural performance under earthquake loading, ultimately contributing to safer and more resilient transport infrastructure.
