Sustainability Switzerland, 2026
Climate change increasingly affects the sustainability and reliability of urban water and wastewater infrastructure. This study analyzes the relationship between climatic variables and the frequency of failures in water and sewage networks in northeastern Poland, using operational data from the Mrągowo system (2020–2023) and meteorological records from 1966 to 2023. Statistical analyses and trend assessments were employed to identify climate-related failure patterns and infrastructure vulnerabilities. Climatic parameters—including temperature extremes, precipitation, snow cover, and sunshine duration—were analyzed in relation to infrastructure reliability. The results indicate rising temperatures, reduced snowfall, and altered precipitation regimes. Although extreme cold corresponded with increased sewage network failures, no significant association was found for high temperatures. Precipitation and snow cover showed weak correlations, except during heavy rainfall events. The study highlights the need to integrate climate resilience into water infrastructure management through preventive maintenance, smart monitoring, and nature-based solutions. Findings contribute to sustainable urban development strategies by demonstrating how climate variability directly affects service reliability. By identifying climate-sensitive failure thresholds, the study supports sustainable infrastructure management by enabling risk-informed adaptation strategies that reduce service disruptions, resource losses, and environmental impacts. This case study offers methodological insights and empirical evidence that may support the assessment of climate-related vulnerability of water and wastewater infrastructure in similar urban contexts. - Matrix Method of Defect Analysis for Structures with Areas of Considerable Stiffness Differences

Applied Sciences Switzerland, 2025
The paper presents an innovative matrix method for defect analysis in heterogeneous structures with significant differences in stiffness parameters. The proposed approach modifies the finite element method (FEM) by introducing a refined type of finite element capable of handling regions with varying material and geometrical properties. Unlike traditional FEM discretization, which increases computational time calculations due to mesh refinement in stiffness-variable areas, the proposed method maintains a consistent discretization while adjusting shape functions to reflect internal stiffness changes. An original functional for modifying linear shape function distributions is introduced, leading to piecewise broken-line shape functions. This enhancement significantly improves the accuracy of numerical calculations, as verified by computational calculations. The explicit formulation of the stiffness matrix enhances computational efficiency, making the approach particularly useful for periodic structures with inclusions, voids, or localized material defects. The results of numerical tests demonstrate that the proposed method provides solutions closely aligned with conventional FEM results while substantially reducing computational costs. The approach is particularly relevant for structural engineering applications where defect analysis and material heterogeneity play a critical role in design and safety evaluation. - Reverse engineering as a non-invasive examining method of the water tower brick structure condition

Materials, 2023
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. - The influence of the fire temperature on the condition of steel roof structure

Engineering Failure Analysis, 2021
The work concerns the procedure of examination and assessment of the condition of external curtain walls used in typical prefabricated residential construction systems at the end of the 20th century in Poland. External partitions were formed from a concrete structural layer, thermal insulation made of expanded polystyrene or mineral wool with variable thickness and a layer of textured concrete. The insulating and texture layers were attached to the structural panel through connectors known as “hangers”. The durability of the exterior barrier, planned at the design stage for 50 years, is determined by the effectiveness of the execution of both concrete layers’ connections. The technical condition of more than one hundred buildings assembled in the large-panel technology was carried out after 35-50 years of operation, usually prior to the thermo-renovation of the buildings planned by the users or before the end of the designed period of use. Various research techniques were used, non-destructive testing has allowed to limit the required number of destructive tests. The test results, assessing actual physical and mechanical parameters of the materials used for the construction of connections, permitted to build calculation models and verify the effort state of structural elements. As a result of the research, calculations and analyses, a concept of effective reinforcement of threatened connections was developed. In addition, recommendations regarding effective testing of interlayer connections that are difficult to reach were formulated. - Special finite elements with adaptive strain field on the example of one-dimensional elements
