Title: Structural Testing of Enhanced Post-Tensioned Concrete Masonry Walls
Author(s): Peter T. Laursen and Jason M. Ingham
Publication: Structural Journal
Appears on pages(s): 852-862
Keywords: concrete masonry; design; post-tensioning; prestressing; seismic; test; wall
Abstract:The in-plane response of post-tensioned concrete masonry walls with unbonded tendons, incorporating strengthened masonry and enhanced energy dissipation, is examined by means of structural testing. An introduction to the testing program is followed by a presentation of the results from structural testing of five fully grouted walls. Discussion of the results is concerned with wall structural response in terms of flexural strength, displacement capacity, tendon stress, and masonry vertical strain, and makes comparison with testing of unconfined (ordinary) post-tensioned concrete masonry walls.
