Constructability of Segmental Concrete Masonry Tall Walls

Tall loadbearing masonry walls are part of the main structural system used in warehouses and industrial facilities. These buildings feature exterior walls ranging from 4 to 9 m in height. Construction of such walls requires special considerations, such as using scaffolds and extra mason efforts to lay blocks around bar splices. Current construction methods create uncomfortable environments for masons, increasing the risk of injuries and time construction while reducing productivity. This paper introduces a new construction method that enhances the constructability of tall masonry walls and reduces the difficulties associated with traditional construction methods. Five reinforced masonry modular panels-eight courses high- were built using 20 cm concrete masonry units to form a full-scale 9 m tall masonry wall. These panels were assembled on top of each other while ensuring mild rebar continuity using mechanical couplers. Post-tensioning threaded bars were also used to ensure wall integrity and enhance wall performance under out-of-plane loads. The experimental results showed good performance of the new wall system while the effect of post-tensioning force and the base condition on the wall performance is discussed.
