Novel panel system for concrete masonry walls

Masonry is one of the oldest materials that humans use for construction. It durable, as seen on ancient structures built thousands years ago, yet still in excellent shape. Recently, masonry walls have struggled to be competitive among other construction such precast concrete, tilt-up walls, timber, etc. This mainly due practices and lack a standardized modular system prevents offsite In this paper, new methods concrete are proposed. These based building partially grouted panels can onsite or offsite, then transported assembled site. The commonly restrained unbonded post-tensioned (UPT) threaded bar join panels. A full-scale experimental program campaign at University Alberta (UOA) currently undergoing test proposed methods. Numerical models were developed before investigation assess behaviour techniques under out-of-plane loading. Bare joints, connecting reinforcement, grouting joints three types panel connections here. influences magnitude prestressing lateral restraints stiffness also studied. results show approaches comparable traditionally constructed with improved serviceability. Also, because relative ease post-cracking behaviour, reinforcement preferred method. Whereas increasing level enhances service conditions but leads premature failure. high stiffness, grout steel, essential enhance behaviour.
