“…There have been a few studies investigating the flexural strength of a PT masonry wall resisting out-of-plane loads [32][33][34][35][36]. To the authors' best knowledge, all the literature on the masonry PT walls subject to out-of-plane loading had mortar in the joints of the masonry blocks.…”

The application of unbonded post-tensioning (PT) in structural walls has led to the development of advanced self-centring (rocking) shear wall systems that has significant advantages, including accelerated construction due to the incorporation of prefabricated elements and segmental construction for different materials (e.g., concrete, masonry, and timber), reduced residual drifts, and little damage upon extreme seismic and wind loads. Concrete, masonry, and timber are often used for the construction of unbonded PT structural wall systems. Despite extensive research since the 1980s, there are no well-established design guidelines available on the shear wall configuration with the required energy dissipation system, joint’s locations and acceptance criteria for shear sliding, confinement, seismic performance factors, PT loss, PT force range and residual drifts of shear walls subjected to lateral loads. In this research a comprehensive state-of-the-art literature review was performed on self-centring shear wall system. An extensive study was carried out to collect a database of 100 concrete, masonry, and self-centring shear wall tests from the literature. The established database was then used to review shear walls’ configurations, material, and components to benchmark requirements applicable for design purposes. The behaviour of concrete, masonry and timber shear walls were compared and critically analysed. The general behaviour, force-displacement performance of the walls, ductility, and seismic response factors, were critically reviewed and analysed for different self-centring wall systems to understand the effect of different parameters including configurations of the walls, material used for construction of the wall (concrete, masonry, timber) and axial stress ratio. The outcome of this research can be used to better understand the behaviour of self-centring wall system in order to develop design guidelines for such walls.

“…This system ensures the stationary positions of blocks at the boundaries of the structure by either kinematic constraints or in-plane forces. In practice, it is realized by constraining frames, e.g., [189,190], self-weight of the structure, e.g., [191], and post-tensioned cables and tendons, e.g., [192,193]. The self-weight and dead loads acting in the plane of a mortarless structure produce an externally applied constraint force, while the post-tensioned cables generate an internal constraint force.…”

Modern economic, social and environmental challenges require a new type of construction that ensures resilience, low construction costs and ease of maintenance. Material production, manufacturing of structural elements and final assembly should minimise the environmental impacts, such as greenhouse emissions and waste production. This review aims to identify the key routes of research and development required to address the environmental challenges the construction industry faces. It outlines recent advances and highlights the rising opportunities. The strategies with great perspectives include 3D concrete printing, prefabrication and modular construction, mortarless construction, development and utilization of sustainable, smart and composite materials, renewable energy systems and automation technologies including the Digital Twin technology. Hybrid approaches that combine traditional and novel construction methods present the greatest potential. Overall, collaboration between stakeholders is crucial in driving innovation and successfully implementing these advancements.

“…This study also contributes to the research area of mortarless construction and thus proposed a modified interlocking sequence of construction using clay bricks. Unlike the other studies [25][26] using interlocking concrete blocks, it is fast, reliable, and cost-effective for underdeveloping countries and exclusively for the Asian countries where clay bricks are the eminent building units.…”

The rising cost of construction materials need to adhere alternate construction techniques and materials. Mud brick is one of the common and basic construction units since thousands of years. In this research study the bricks with mechanical interlocking mechanism are used for comparison over economical, sustainable, environment friendly and fast track construction especially for the flood and earthquake affected areas. Naturally destructive areas require quick rehabilitation of the displaced people. A parametric study has been performed in compassion with conventional brick masonry. Performance evaluation for construction cost and time has been studied along with the durability of system to check the acceptability of mortarless masonry construction technique.
