CSIR-CBRI Technology: Enhancing Masonry Wall Safety through Bed Joint Reinforcement

CSIR-CBRI Technology: Enhancing Masonry Wall Safety through Performance-Based Reinforcement Excited to share a brief overview of our work on: “Process Know-how for Performance-Based Safety of Walls using Prefabricated High-strength Steel Cord Reinforcement (PHSR)” With increasing emphasis on resilient infrastructure and seismic safety, masonry infill walls continue to remain one of the most vulnerable non-structural components during earthquakes and extreme wind events. Our developed framework focuses on improving the out-of-plane performance, crack control, ductility, and structural reliability of AAC masonry infill walls using Prefabricated High-strength Steel Cord Reinforcement (bed-joint reinforcement). Key highlights of the work include: Experimental investigation on full-scale AAC wall panels under realistic loading and boundary conditions Evaluation of reinforcement spacing, anchorage systems, RCC band integration, wall thickness, and reinforcement configurations Significant improvement observed in: Ultimate load capacity Ductility and deformation behavior Crack distribution and crack control Post-peak stability Energy dissipation characteristics The study further establishes: Optimum reinforcement spacing recommendations Rational optimization of reinforcement layers Anchorage detailing guidelines Hybrid strengthening approaches combining PHSR with RCC bands for seismic regions One of the important outcomes of this work is bridging the gap between commercially available reinforcement systems and their effective field implementation through experimentally validated and implementation-ready recommendations. This framework can contribute significantly towards: Safer masonry construction Enhanced seismic resilience Performance-based engineering practices Improved serviceability and durability of infill wall systems As the construction sector moves towards resilient and performance-oriented infrastructure systems, such technologies can play a vital role in minimizing non-structural damage and enhancing occupant safety.
