  • Clay-Based Grout Injection for the Consolidation of Masonry Walls at Wupatki Pueblo: An Applied Investigation
    Laura Gambilongo, Rui A. Silva, Alberto Barontini, Rafael Ramirez, Paulo B. Lourenço
    International Journal of Architectural Heritage, 2026
    This study investigates the application of clay-based grout injection for consolidating masonry walls at the Wupatki Pueblo archaeological site (Arizona, USA), which have experienced accelerated degradation phenomena due to harsh environmental conditions. Three trial zones were selected for injection, each one evaluated based on the injected grout volume and on non-destructive testing, namely impact-echo and sonic tests. A compatible clay-based grout mixture with adequate fluidity, strength, and durability was designed using local soil. Fluidity was measured during works using the Marsh cone test, while compressive strength was evaluated afterwards. The volume of injecThe authors report that there are no competing interests to declare.ted grout was monitored during execution, and impact-echo and indirect sonic tests were conducted before, shortly after, and one-year after the intervention. The injected grout volumes exceeded the initial estimations in all zones, indicating wider crack extents and interconnected voids within the masonry. After injection, an increase in wave velocity was observed in most sonic tests, suggesting the effective filling of cracks, while the comparison of frequency spectra obtained from impact-echo tests yielded inconclusive results. Overall, the findings suggest that clay-based grout injection is a suitable intervention for consolidating masonry walls at the Wupatki Pueblo, although long-term issues, such as grout deterioration and crack reopening, should be monitored.

  • Field Investigation and Numerical Modeling for the Seismic Assessment of the Castle of Lanjarón, Spain
    Hayden Luger, Rafael Ramirez, Paloma Pineda, Paulo B. Lourenço
    Applied Sciences Switzerland, 2025
    The Castle of Lanjarón is a 16th century stronghold located in Andalucía, Spain. After losing its military function, the castle was abandoned, leading to significant decay. Designated a national heritage site in 1985, recent efforts have sought to preserve its historical and cultural value. This study outlines an inspection and diagnosis campaign carried out on the castle. Non-destructive tests (NDTs) were employed to characterize the properties of the masonry, using both mechanical and wave-based methods. Dynamic identification was performed to determine dynamic and modal properties of the structure, which were used to develop and calibrate a three-dimensional (3D) finite element model (FEM) of the west wall, based on homogenized masonry material. Limit analysis and non-linear static (pushover) analysis under various boundary conditions were conducted to determine the maximum relative load factor in the out-of-plane direction. The results were compared to the expected peak ground acceleration (PGA) of the area, showing that the maximum load capacity of the wall exceeds local seismic demands with a safety factor of 1.39. The study highlights the efficacy of pairing a homogenized macro-modeling approach with wave-based and dynamic identification methods, particularly for resource efficiency. Finally, recommendations for future conservation efforts have been provided.

  • Seismic Assessment of the National Museum of Archaeology in Lisbon, Portugal

    International Journal of Architectural Heritage, 2025
    Structural assessment of historic unreinforced masonry structures faces multiple challenges due to geometric complexities, material heterogeneity and phased reconstructions. Code-based seismic evaluation is essential, focused on displacement performance, to conclude on the current safety and optimization of retrofitting schemes. This study delivers a comprehensive methodology, combining inspections, ambient vibration testing, advanced numerical and kinematic analyses to evaluate the seismic and gravitational safety of the National Museum of Archaeology in Lisbon, Portugal, part of the UNESCO-listed Jerónimos Monastery. Nonlinear pushover analyses and displacement-based assessment of the galleries revealed that seismic safety is satisfied for the usual design code earthquake, but showed vulnerability under severe earthquakes. The improved lateral capacity from a reinforced roof was demonstrated. An additional retrofitting scheme of embedded steel tie rods could enhance lateral capacity and ductility by 40%, while maintaining the structure’s aesthetic integrity, but at a high cost. This research provides a critical framework for evaluating the seismic performance and retrofitting of heritage structures, balancing modern building codes with conservation principles to ensure long-term structural safety and cultural preservation.

  • Industry 5.0, towards an enhanced built cultural heritage conservation practice
    Alejandro Jiménez Rios, Margarita L. Petrou, Rafael Ramirez, Vagelis Plevris, Maria Nogal
    Journal of Building Engineering, 2024
    The rise of Industry 4.0 has led to a rapid increase in digitalization and industrial operations. However, it has recently been deemed insufficient in fulfilling European objectives for 2030. In response, and to counteract the unintended negative consequences triggered by Industry 4.0, Industry 5.0 has been introduced. The purpose of this article is to shed light on how the architecture, engineering, construction, management, operation, and conservation industry can adapt and better prepare to embrace novel Industry 5.0 principles and enabling technologies, ultimately resulting in enhanced conservation practices for the built cultural heritage environment. To achieve this, a systematic literature review was conducted following the PRISMA methodology. The principal results of this article highlight the work of different conservation professionals and our views on the potential of Industry 5.0 for enhancing conservation practices. Major conclusions indicate that artificial intelligence and digital twins are the two most studied technologies in the field. Sustainability is broadly discussed throughout the analyzed literature, whereas resilience and human centrism require further research and implementation efforts to achieve a holistic Industry 5.0 adoption. The significant scientific novelty of this work lies in the comprehensive scope of the review in terms of principles and enabling technologies, with a particular emphasis on heritage buildings. Thus, it is valuable for conservation practitioners seeking best practices, for policymakers as it suggests ways to encourage the adoption of novel technologies and principles in conservation, and for researchers as it highlights gaps and stimulates further paths of research and innovation.
  • Evaluating the Role of Mortar Composition on the Cyclic Behavior of Unreinforced Masonry Shear Walls
    Meera Ramesh, Rafael Ramirez, Miguel Azenha, Paulo B. Lourenço
    Materials, 2024
    The mechanical behavior of unreinforced masonry (URM) shear walls under in-plane cyclic loading is crucial for assessing their seismic performance. Although masonry structures have been extensively studied, the specific influence of varying lime content in cement-lime mortars on the cyclic behavior of URM walls has not been adequately explored. This study addresses this gap by experimentally evaluating the effects of three mortar mixes with increasing lime content, 1:0:5, 1:1:6, and 1:2:9 (cement:lime:sand, by volume), on the cyclic performance of brick URM walls. Nine single-leaf wall specimens 900 mm × 900 mm were constructed and subjected to combined vertical compression and horizontal cyclic loading. Key parameters such as drift capacity, stiffness degradation, and energy dissipation were measured. The results indicated that the inclusion of lime leads to a moderate improvement in drift capacity and ductility of the walls, with the 1:1:6 mix showing the highest lateral capacity (0.55 MPa), drift at cracking (0.08%), and drift at peak capacity (0.31%). Stiffness degradation and energy dissipation were found to be comparable across all mortar types. These findings suggest that partial substitution of cement with lime can enhance certain aspects of masonry performance. Further research is recommended to optimize mortar compositions for unreinforced masonry applications.
