Strength of Unbonded Post-Tensioned Walls
Post-tensioned masonry walls (PT-MWs) will be an ideal candidate for accelerating the construction of sound barriers in highways. PT-MWs have been in use for a while; however, there has been no rigorous single-study in the United States about in-plane strength of PT-MWs built out of concrete masonry units. This project will investigate the in-plane behavior of six full-scale unbonded post-tensioned walls. All the walls will have the same total post-tensioning force and identical dimensions of 104 in. long, 96 in. high, and 8 in. wide. Spacing between tendons ranging from 32 in. to 96 in. will be investigated. The walls will be subjected to in-plane shear loads of increasing amplitude. Both flexural strength and shear strength will be evaluated and compared to the strengths given by MSJC (2011). The stresses in the tendons will be measured using strain gauges and compared to different formulae.
