“…The standard [ 26 ] recommends for the designed masonry structures to adopt the value of this coefficient as for reinforced concrete structures, at the level of γ Rd = 1.1. In the case of existing masonry structures, the detailed identification of which is limited, it is proposed to adopt slightly higher values, e.g., γ Rd = 1.15 [ 50 ]. In the article, an attempt was made to determine the value of γ Rd for the analyzed compressed masonry structures.…”

Technological progress in masonry structures has resulted in the creation of competitive solutions, which force the need for an ever deeper recognition of this type of structure. Masonry is a composite with heterogeneous strength properties. Therefore, the most appropriate way to accurately describe the behavior of the masonry structure under the influence of the working load are experimental research and their statistical and probabilistic analysis. This article presents a series of experimental tests carried out on real masonry structures. The results of the experiments were subjected to static evaluation, determining the most important parameter in the probabilistic analysis—the coefficient of variability of strength. The variability obtained in the experimental studies was used to determine the safety of the structure in the probabilistic method. Achieved values of coefficients of variation and safety coefficients proved to be satisfactory and adequate to the emerging technological progress in the production and embedding of masonry components.

“…Modern technology has radically changed the way we create and communicate the information necessary to create inventory and design documentation. The most significant thing about these advanced technological methods has become that they enable non-invasive examination of the condition of each building and the use of innovative technological and material solutions [33,34,25,20,21,35,19]. Historic buildings are also often characterized by complex geometry, many elements of small architecture, ornaments or decorations, which results in the need for a thorough and comprehensive data acquisition technology, for which TLS can be best used.…”

Terrestrial laser scanning (TLS) technology is increasingly used in surveying, construction and architecture. The potential of the data obtained by this method creates the possibility of its versatile application also in conservation and revitalization of monuments, archaeology or history. The use of this technology during the creation of architectural documentation of a historic building greatly facilitates the acquisition of comprehensive information about its actual condition in a fast, non-invasive and very precise manner. Thanks to digital technology, it also creates the possibility to accurately interpret the condition of an object and present its model in a virtual space. This technology provides the ability to transfer acquired image elements with high accuracy of their mapping to plans and designs prepared by architects and contractors. It is also possible to maintain high technical standards in the processes aimed at the preparation of the required graphical studies, thanks to the use of the point cloud obtained in TLS. One of the most important advantages of using this measurement method is the possibility of combining it with data from e. g. from photogrammetric tools, which gives the possibility to fill in the missing elements creating a more complete picture of the needed data. This paper presents the implementation of terrestrial laser scanning technology as a non-invasive method for the modelling of walls and buildings of the so-called “greenfield”. Revers BIM on the example of the measurement of the facades of the buildings of the old market in Jarosław. This technology allows for preparation of precise architectural documentation including: projections, sections, elevation views, 3D models or multimedia visualizations. The use of TLS for cultural heritage research also enables the preparation of fully complete documentation for conservation and restoration works aimed at maintaining the current state of monuments or even at reconstructing their damaged architectural elements.

“…Then, a reliability model was also used in order to estimate the reliability of this mechanical model, while proposing a method for estimating the distribution laws of the different random variables used in the mechanical model, by a response surface coupling technique between the two models. Some applications of reliability analysis for reinforced concrete structures have been reported by (Schlune et al [32], Allaix et al [33], El Ghoulbzouri et al [34]; Olmati et al [35]; Słowik et al [36]), and prestressed concrete structures by (Rakoczy and Nowak [37], Hadidi et al [38]). The combination of nonlinear analysis with reliability methods for the assessment of the reliability index has been used (Robuschi et al [39], Slobbe et al [40], Grubišić et al [41]).…”

The object of this article is to be able to simulate the behavior of reinforced and/or prestressed concrete beam’s section in the shear loading through a model allowing the evaluation of nonlinear strains caused by shear, while taking into account the real behavior of the materials. In this approach, we are often confronted with problems of modeling uncertainties linked to some insufficiencies of the mechanical model allowing to describe the physical phenomena in a realistic way. For that, it is necessary to use a reliability model making it possible to evaluate their probability of failure, by establishing failure curves according to the different transition zones of the limit state curve of the nonlinear behavior in the shear loading up to at section failure of reinforced and/or prestressed concrete beams. In this work, we also propose a coupling of the reliability method by response surface to carry out the reliability optimization on complex mechanical models, where the mechanical and reliability models developed have been implemented on the Fortran. This allows the estimation in an efficient way of the different reliability characteristics according to each transition zone from the limit state curve to the real behavior until failure in the shear loading.
