WebOct 16, 2024 · The tests results show that the fully grouted walls exhibited a large lateral drift and small residual deformation, while the partially grouted and ungrouted walls exhibited shear failures. Hassanili et al. [ 17, 18] carried out an experimental study on four unbounded posttensioned masonry walls. WebThe partial depth shear key is generally filled with a high-strength, low-shrinkage grout as shown in Figures 1 and 2. Ties are generally placed at even intervals up to 20 ft apart. The ties are used to snug the adjacent members together before placing the grout in the key.
