Understanding The Dynamic Behavior of Junctions in Mortar-free Interlocking Block Walls Through Literature Research

This paper presents a comprehensive review of the dynamic behavior of junctions in mortar-free interlocking block walls under harmonic loading, emphasizing their seismic resilience and structural performance. With the rising frequency and intensity of earthquakes, there is a critical need for sustainable and cost-effective construction techniques. Mortar-free interlocking block systems have emerged as a promising solution, offering advantages such as reduced construction time, cost efficiency, and improved environmental sustainability. This study integrates finding from global experimental, numerical and analytical investigations, encompassing shake table tests, finite element modeling, and cyclic loading experiments. It examines critical factors affecting T-junction performance, including interlocking mechanisms, block geometries, material properties, and reinforcement strategies. Research highlight that well-engineered junctions play a pivotal role in enhancing structural integrity and mitigating failure under seismic events. However, certain limitations persist in terms of junction misalignment, inadequate reinforcement, and block displacement under harmonic loading conditions. The review reveals critical gaps in the existing body of research, including the necessity for large-scale experimental investigation, field validation, and optimization of junction design parameters. Future research directions are suggested to address these challenges, aiming to enhance the resilience and reliability of mortar-free interlocking block structures in earthquake-prone zones. This study contributes to advancing construction practices and fostering innovative solutions for sustainable and disaster-resilient infrastructure systems.
