“…The category of assembling modality of the structural materials [23] determines its structural behavior [24]. The preservation and conservation of cultural architectural and structural engineering fields' heritage are complex challenges [25][26][27][28]. Structural evaluation of buildings [29] and stone conservation techniques and strategies [30][31][32] require an interdisciplinary approach based on scientific assessment.…”

The research reviews the environmental and cultural sustainability of the architectural elements of two mosques in the historical area of Jeddah, Al-Shafi’i Mosque and Al-Mimar Mosque. Through the research methodology, the environmental and cultural sustainability of the two mosques in the historical Jeddah area were compared, as how they were treated and reused in different ways and the architectural elements were analyzed. The results of the research indicate that sustainability. The environment is rebuilding some walls, reducing waste by using existing walls, not using new materials as much as possible, and reducing the entry of solar radiation into the building through wooden windows (Roshan). As for cultural sustainability, it is through contributing to a pioneering project that achieves the rehabilitation of the mosque to increase the number of worshipers and its use by visitors and residents of the city of Jeddah to be a distinguished center for reviving the meetings of the people of old Jeddah and enriching the social environment. As for economic sustainability, it is through the financial return of commercial activities around the mosque, the creation of job opportunities for Saudi youth, and the work of a distinguished pioneering project to encourage government agencies and real estate owners in the historical area of Jeddah, to carry out similar projects that support the development and economic sustainability, and achieve the vision of the Kingdom of Saudi Arabia 2030, as the most important recommendation for research.

“…The on-going restoration work began in 2012, and provide the opportunity to examine the material context of the building, which represents a previously unexplored historical record (Montevecchi and Sutter 2014), along with features related to its structural stability (Bennati et al 2020). The petrographic survey carried out in the matroneum noted a huge chromatic alteration of the stone surface on a coarse-grained calcarenite, which changed its colour from yellow to deep red; in some areas, dark deposits at the stone surface may be related to the effects of a fire.…”

Recent restoration work on Pisa Cathedral provided the opportunity for a multidisciplinary analysis of the monument that identified interesting aspects of its history, conservation and structural safety. In particular, the study of the matroneum provided clues about the role of the structures in the well-known fire that occurred in 1595. Alteration patterns and damage forms on the stone masonry walls were analysed to better understand their relationship with this catastrophic event. The investigation of the stone specimens enabled textural and mineralogical features typical of fire damage to be identified on the surface. The evidence of fire also provided a terminus ante quem to correctly interpret and diachronically date a damage pattern consisting of cracks in the eastern arch supporting the dome. The cracks were likely to have been induced by a soil consolidation phenomenon related to the renowned leaning of the Pisa tower, centuries before the fire.

“…A multidisciplinary research project started in 2016 is still being carried out by the authors with the aim of determining the structural response of the dome through a thorough assessment of its geometry and constituent materials, and by taking into account historical and architectural aspects as well. The activities carried out as part of the project involved conducting several steps, in particular: (i) an archival investigation of the historical development of the construction [1,2,3,4], (ii) a detailed high-density survey of the geometry using both laser scanning and photogrammetric techniques [5], (iii) in-situ and laboratory tests on construction materials aimed at determining their mechanical and chemical-physical properties [6], (iv) the definition of a suitably designed geometric model that could wholly and analytically describe the shape of the dome [7] and (v) a series of structural analyses using different mechanical models and analysis methods [6,7,8,9,10]. The problem of modelling the mechanical response of complex systems such as historic masonry structures is a topic widely addressed by the scientific community.…”

Statically Admissible Shell Internal Forces for the Stability Analysis of the Dome of Pisa Cathedral Loaded by Vertical and Horizontal Loads

The present contribution illustrates some recent results concerning the stability analysis of the oval-based pointed masonry dome of the renowned Pisa Cathedral subjected to both vertical and horizontal loads. The study is aimed at determining lower bounds of the horizontal collapse load by making use of the static theorem of limit analysis. Heyman's hypotheses are adopted, i.e., masonry is assumed to have unlimited compressive strength and zero tensile strength while collapse due to sliding is assumed to be prevented. The structural analysis is carried out by modelling the dome as a thin shell; an ad-hoc solution procedure is enforced which is able to define optimised statically admissible stress fields. The results in terms of stress distribution and safety factor are discussed. 1810COMPDYN 2023 9 th ECCOMAS Thematic Conference on Computational Methods in Structural Dynamics and Earthquake Engineering M.
