Post-Tensioned Single Wythe Concrete Masonry Walls
This study investigates post-tensioning as a means of increasing the flexural strength of single wythe concrete masonry walls. Wall panels are constructed of conventional concrete masonry units and mortar, the properties of which are determined. The wall panels are post-tensioned and grouted solid. Three groups of wall panels are post-tensioned with a different amount of post-tensioning force. A reinforced masonry wall panel is also constructed. The panels are tested in flexure. Each post-tensioned panel is tested twice. Based on strain data obtained during the first test, cracking moment is determined. In the second test, several panels are tested to failure. The flexural behavior of reinforced and post-tensioned masonry observed during testing is discussed. The deformation of the masonry caused by grouting, shrinkage and creep in two panel is monitored or a period of 90 days. The procedure used to design the post-tensioned wall panels is discussed. The construction of a post-tensioned wall in actual practice is examined.
