Description
Recent research on the seismic retrofit of existing masonry buildings has emphasised the need for techniques that ensure structural safety while remaining sustainable, compatible, minimally invasive, and reversible. This study presents recent advancements in these retrofitting methods for the in-plane strengthening of historic and traditional masonry structures, with particular attention to the use of natural materials and advanced metals. The work reviews the evolution of the Reticulatus technique—based on the insertion of reinforcement within mortar joints—as well as the application of CLT panels for shear strengthening. Both CLT and advanced metals offer favourable strength-to-weight ratios, durability, and corrosion resistance, making them suitable for long term use in heritage contexts. When combined with lime-based mortars, these systems enhance mechanical compatibility while preserving vapour permeability and reversibility, which are essential for conservation. Experimental and analytical results show that such approaches can improve shear and compressive capacity, limit crack propagation, and reduce seismic vulnerability without altering the architectural fabric. The use of lime matrices also contributes to sustainability by lowering embodied carbon. However, the study also highlights challenges associated with lignocellulosic natural materials, including variability, durability concerns, and the resulting complexity in structural design.| Period | 9 Jun 2026 |
