“…Examples of testing procedures using NDT or semi-destructive techniques (SDTs) are popular in the literature [19][20][21], especially due to increasingly widespread access to devices enabling this type of analysis [22,23]. Numerous described analyses and examples of specific studies [24,25] also confirm the validity of using these methods in historic buildings.…”

The evaluation of the technical condition of historic buildings that have operated for several hundred years is a complicated issue. Even buildings that are in very poor condition must be checked and assessed in terms of their further repair, strengthening, or compliance with conditions that allow the facility to be safely operated. Most 18th-century buildings have not survived to this day retaining their original arrangements and structural elements. Renovations and repair work in the past were often carried out using materials of uncertain quality, with repair work of different qualities and without detailed analysis or methodology, based only on the experience of the former builders. In historic structures, the character of the work of individual structural elements has often changed due to significant material degradation, the poor quality of repair work, or the loss of adequate support. When load transfers change, internal forces are redistributed, and, as a result, the static scheme changes. This article presents an overview of identified defects affecting the change in static schemes in historical building structures built in the 18th century, using the example of a historic building with a large number of aforementioned defects. The process of assessing the technical condition of the facility is presented, in which non-destructive testing (NDT) methods were used. Detailed computational analyses were carried out for the wooden roof truss structure, which had partially lost its support.

“…Only by uncovering, it is possible to fully assess the quality of brick and mortar and their degree of degradation. The evaluation of the material properties of the structure is possible by taking representative samples and performing laboratory tests [2,10,[54][55][56][57][58][59]. A deeper analysis of the performance of the structure and the causes of its damage is possible using FEM-based 3D models [57][58][59][60][61][62][63][64].…”

Research and TLS (LiDAR) Construction Diagnostics of Clay Brick Masonry Arched Stairs

et al. 2022

The study presents the terrestrial laser scanning (TLS) diagnostic of the clay brick masonry arched staircase in a historic building. Based on the measurements of the existing arched stair flights, 1:1 scale experimental models with and without stair treads were made. Strength tests of the models were carried out for different concentrated force locations in relation to the supporting structure. Force, deflections and reaction in the upper support of the run were measured during the tests. The influence of the masonry steps on the curved vault on the load capacity and stiffness of the run structure was analyzed. The conducted experimental investigations showed that the key element responsible for the actual load-bearing capacity and stiffness of this type of stair flights were the treads above the masonry arch.

Apesar do grande interesse cultural e social despertado pelas edificações históricas, grande parte das edificações inventariadas pelos municípios carecem de cuidados, demonstrando a falta de preocupação e de conhecimento, dos proprietários, e usuários com a preservação do patrimônio edificado. As fachadas, como elementos mais externos das edificações, estão sujeitas de forma mais severa à ação de agentes agressivos, tornando-se necessário a adoção de métodos de controle e acompanhamento do avanço da degradação sofrida por estas edificações. Dentre as diversas metodologias existentes para avaliar a degradação sofrida pelas edificações, este estudo teve como objetivo determinar uma amostra de fachada inventariadas pelo Município de Santo Ângelo/RS, para determinar a viabilidade do uso do Mapa de Danos através de imagens feitas in loco e pelas ferramentas online, avaliando as limitações existentes na aplicação da metodologia nas imagens, tendo em vista que o grande obstáculo para a aplicação do método está em obter imagens sem interferências como vegetações, toldos, banner, placas, entre outros. Ao todo foram avaliadas 82 fachadas, destas, apenas 16 estavam aptas para a aplicação da metodologia, demonstrando que apesar de ser uma ferramenta amplamente utilizada na análise de manifestações patológicas, o Mapa de Danos possui limitações quando aplicado diretamente em imagens. A aplicação do Mapa de Danos na Antiga Casa Rei Sabo demonstra o que ocorre com grande parte das edificações analisadas, onde as manifestações patológicas que ocorrem com maior intensidade estão relacionadas a falta de manutenção, como por exemplo o descolamento da pintura e as manchas de umidades Palavras-chave: Degradação; Mapa de Danos; manifestações patológicas; fachadas.
