“…The corrosion of reinforcing steel is the most destroying pathology that reinforced concrete structures (RCS) present, considered by the experts the main causative factor of the operation, durability and useful life decrease of the RCS [1]- [4], what means a big problem of premature economic costs or medium period in addition to a negative impact to our society due to the uncertainty of possible significant structural failures in civil works [5]- [12].…”

In the present investigation, the protector against sulfate corrosion of reinforcing steel AISI 1018, which provides the Eco-friendly Concrete system CPC-SCBA-SF, was evaluated. This system was made with CPC-SCBA-SF cementitious materials, in percentages of 90-5-5 and 80-10-10 respectively, with exposure of the concrete specimens to a 3.5% MgSO4 solution, an experimental arrangement that simulates the foundations of Civil Works such as bridges, buildings, pavements, etc.; in soils contaminated with sulfates. The design of the concrete mixtures was in accordance with the ACI 211.1 method. The behavior of the corrosion potential Ecorr and the corrosion rate (icorr) of the AISI 1018 steel embedded in Conventional Concrete (CC) and in the EC were evaluated during a period of 180 days of exposure to an aggressive environment. The Ecorr values indicate between a 10% risk of corrosion and uncertainty, according to the ASTM C-876-15 standard, but the icorr indicates a negligible level of corrosion but with a tendency towards the activation of the system, with the eco-friendly concrete EC-20 having the best performance.

“…This is indicating the significant role interplay between the stainless steel and other DM variable factors. This is the proof that Stainless Steel is responsible for the high cost of the DM (Rabi, Shamass, & Cashell, 2022). It therefore suggests that replacement of stainless steel with another viable material like hard plastic will drastically reduce the cost DM production (Olorunnisola, 2021).…”

Some concerns had been expressed over the success rate of the De-feathering machine (DM) in Nigeria. Therefore, it is imperative to evaluate DM in selected poultry farms in Ekiti State, Nigeria, and consider the factors that inhibit their viability. This study seeks to verify the success rate and identify factors that pose challenges to DM and provide a solution to their intercorrelations. Kendall Coefficient of Concordance (KCC) and Principal Component Analysis (PCA) was the design framework used to investigate the identified factors that influence DM. The KCC was used to analyse the data matrix generated by 12 Judges who ranked the twenty-eight identified factors that influenced DM in ascending order, upon which basis an index of concordance in ranking among the judges was computed as w = 0.70. PCA was used to further analysed questionnaires crafted with the twenty-eight well-ordered factors, purposively selected, using statistisXL version 2021.2 software. Also, the result obtained by PCA indicates that factor reduction was achieved from twenty-eight variables to seven clusters using a scree plot graph. Furthermore, Cost of Material cluster 5 (consisting of dual factors; ‘stainless steel’ and ‘material selection’) wielded the highest factors loading of 0.847 and 0.779 respectively. This study has helped to justify unsatisfactory DM operating costs among poultry farmers in Nigeria and clarify challenges associated with the high cost of material selection in DM design.

“…There is a general scarcity of experimental research on the structural behaviour and design of CHS beam-columns, including hot-finished [7][8][9][10], coldfinished [8,[11][12][13] and fabricated CHS [14,15]. The coldformed CHS exhibit a continuous rounded stress-strain response caused by cold-working throughout the forming process, whereas the hot-finished CHS have a linear elastic response followed by well-defined yield plateau and moderate degree of strain hardening [16][17][18][19][20][21]. More recently, Meng and Gardner [22] conducted a series of experimental and numerical tests on hot-finished and cold-formed CHS beam-columns made from both normal-and high-strength steels.…”

The use of circular hollow sections (CHS) has increased in recent years owing to its excellent mechanical behaviour including axial compression and torsional resistance as well as its aesthetic appearance. They are popular in a wide range of structural members, including beams, columns, trusses and arches. The behaviour of hot‐finished CHS beam‐columns made from normal‐ and high‐strength steels is the main focus of this article. A particular attention is given to predict the ultimate buckling resistance of CHS beam‐columns using the recent advancement of the artificial neural network (ANN). Finite element (FE) models were established and validated to generate an extensive parametric study. The ANN model is trained and validated using a total of 3439 data points collected from the generated FE models and experimental tests available in the literature. A comprehensive comparative analysis with the design rules in Eurocode 3 is conducted to evaluate the performance of the developed ANN model. It is shown that the proposed ANN‐based design formula provides a reliable means for predicting the buckling resistance of the CHS beam‐columns. This formula can be easily implemented in any programming software, providing an excellent basis for engineers and designers to predict the buckling resistance of the CHS beam–columns with a straightforward procedure in an efficient and sustainable manner with least computational time.
