“…6 Concrete deformation and its ability to recover after unloading are determined by several factors. When the hysteretic recovery is complete, the residual deformation is referred to as plastic deformation 7 , and it affects the structure's durability (Sugandhini et al, 2022).…”

“…Concrete or reinforced concrete (RC) is used to ensure the structure's long-term durability and, as a result, compliance with standards for reasonable building deformations (Sugandhini et al, 2022). Because of the efficacy of epoxy resin coatings in enhancing concrete durability, structures can withstand a variety of environmental effects (Shaik et al, 2022).…”

Even though experts had been monitoring infrastructure quality previous to the COVID-19 epidemic, they had not normally widely highlighted the importance of constructing high-quality infrastructure. The lifespan of a structure is a significant consideration in evaluating how long it will last. This, however, necessitates a reevaluation of infrastructure durability to promote more sustainable growth. Based on these facts, this paper presents a method for measuring building durability utilizing structure deformation effects. The findings indicate that building durability will be acceptable in cities if building deformations in the serviceability state (SLS) do not exceed those of the ultimate limit state (ULS).

“…As the reduction of the performance of structural components must be manifested in the form of external diseases, the formulation of durability standards can be considered from the perspective of disease conditions and service performance [27,28]. (e qualitative criteria of evaluation indicators and evaluation Reference [12] Reference [13] Reference [14] Reference [15] Reference [ results might be inconsistent, but the focus here was on verification of method applicability.

By integrating rough set theory and neural network theory, this study combined their advantages. Drawing on the existing theoretical results for bridge influencing factors, a method for numerical simulation and data fusion was used in the application of multifactor data fusion for cable-stayed bridge safety evaluation. Based on studying existing bridge safety evaluation methods, a neural network and rough set theory were combined to perform a safety evaluation of PC cable-stayed bridge cables, which provided a new means for bridge safety evaluation. First, a cable-stayed bridge in Shenyang was used as the engineering background, the safety level of its cables was divided into five levels, and a safety evaluation database was established, clustered by a Kohonen neural network. This provided specific evaluation indicators corresponding to the five safety levels. A rough neural network algorithm integrating the rough set and neural network was applied to data fusion of the database, with the attribute-reduction function of the rough set used to reduce the input dimension of the neural network. Conclusions. The neural network was then trained and the resulting trained network was applied to the safety evaluation of the cables of the cable-stayed bridge. Four specific attribute index values, corresponding to the bridge cables, were directly input to obtain the safety status of the bridge and provide corresponding management suggestions.

“…However, because of its shortcomings, including low tensile strength, high brittleness, and poor crack resistance, concrete is susceptible to the influence of the complex surrounding environment during long-term use, making it challenging to prevent micro cracks on the surface and interior of concrete. [4] In addition to reducing the durability of concrete structures, cracks in concrete allow corrosive elements from the environment, such as water, oxygen, and chlorides, to enter the material [5]. This leads to issues like leakage, carbonation, and steel corrosion.…”

Cementitious materials are the most common construction material globally. Even though deterioration cannot be prevented once the service life has begun, it still calls for maintenance and repair work, which is frequently labor and resource-intensive. Bacteria and fibres can be used to fix these issues. In this study, Bacillus pumilus bacteria is impregnated in concrete with 107 Cfu/g concentration. Glass fibres are used with 1% in ECC. To find mechanical characteristics like compressive, tensile, and flexural strength, tests were run at 7 and 28 days curing time intervals. The mechanical strengths of ECC are enhanced by the combination of fibres and bacteria due the high bridging ability, increase the bonding performance linking fibres, fill voids, enhances compactness.
