Topic: Post-Tensioning Tendon Repairs of Two Segmental Concrete Bridges
Time: 12:00PM - 1:00PM
Summary: How to repair post-tensioning (PT) tendons and get bridges back to normal service? This presentation will demonstrate the design and construction of PT tendon repairs for two segmental concrete bridges - Wando River Bridge in Charleston, SC, and N-2 Missouri River Bridge at Nebraska city . The design for both structures utilized a combination of 3D time-dependent staged-construction finite element beam models to evaluate overall behavior and non-linear finite element solid models to evaluate local effects. The repairs included detensioning the damaged tendons and installation of supplemental external tendons, construction of expandable PT systems with post-installed anchors and deviators, and the extension of an existing end diaphragm.

In the national and global market, since joining HDR in 2018, Ying has spent most of her time working on complex bridge analysis and advanced finite element modeling, which includes Los Angeles International Airport Automated People Mover Project, the I-395 signature bridge in Miami Florida, Wando River Bridge Repairs in Charleston South Carolina, Sound Transit’s Tacoma Dome Link Extension in Washington State, and the Ontario Line project in Toronto.
