Construction and Monitoring of Post-Tensioned Masonry Sound Walls.

摘要

This request documents the construction and monitoring of a post-tensioned concrete masonry sound wall built along the US 36 corridor in Westminster, Colorado. The research project was funded by the Colorado Department of Transportation (CDOT) and conducted jointly by Atkinson-Noland & Associates and Dr. Trey Hamilton of the University of Wyoming. The research project began in August of 2000 with the casting of the concrete grade beam supporting the wall. The post-tension anchorages were installed in the plastic concrete of the grade beam. The sound wall was completed in late September and tensioning of the tendons was done on October 2, 2000. A data acquisition system was installed to monitor and record strains in the tendons and was operated for one year after the initial tensioning.
