Abstract: The present study is an investigation into the fire performance of steel-reinforced concrete (SRC) beam–column joints subjected to fire. Two new tests on SRC beam–column joints subjected to the ISO-834 fire standard were carried out and described. A finite-element analysis (FEA) modelling was developed. A comparison of results calculated using this modelling shows generally good agreement with the test results. The FEA modelling is then used to investigate the influence of important parameters that determine the mechanism of the composite joints under fire.

Abstract: In current practice, a relatively wide range of different interconnections and assembly systems is being used for the design of modular buildings made of volumetric prefabricated frames. The integration strategies and design criteria for providing structural robustness or prevention of disproportionate collapse for such buildings are completely different with those with conventional systems. This is mainly because of their fundamentally different configuration of joints and the redundancy they provide for the structure. This paper studies the robustness of multistory modular structures, made of prefabricated volumetric steel frames, against progressive collapse, which can be triggered by various column or module loss scenarios. In this study, the flexibility of modules and propagation of the damage inside the in idual modules are taken into account, and the buckling of columns, as well as the effects of material nonlinearity on the responses and capacity of the entire system, are also considered. Load redistribution patterns and possible gravity‐induced collapse mechanisms are inspected in various collapse scenarios for a typical mid‐rise modular steel frame. In the numerical model, each in idual prefabricated volumetric module is composed of discrete beam and column frame elements, connected through conventional rigid beam–column connections. The volumetric modular steel frames are connected via corner vertical and horizontal intermodule joints each one is modeled utilizing one axial and two shear springs with predefined nonlinear force–displacement behavior in a 3D finite element analysis. The local damage scenarios are assumed to be due to instantaneous loss of columns or entire modules, for which the interactions between the modular units, overall structural robustness, load redistribution, possible collapse mechanisms, and progressive collapse response of the frames are investigated. The results indicate that the additional redundancy may help the modular steel frames survive from some corner column or single module removals but will not be able to maintain their robustness under combined module removal scenarios.

Abstract: Engineers are increasingly encouraged to consider sustainability in the design and construction of new civil engineering infrastructure. Sustainability can be achieved through the use of high strength materials thereby reducing quantity of materials required in construction where possible. Knowledge of residual stresses in fabricated columns is important in identifying whether the fabricated columns can be classified as heavily welded (HW) or lightly welded (LW). The determination of residual stresses can be used to determine the local buckling of stub columns. Residual stress magnitudes are also essential in the numerical modelling of buckling behaviour of columns. This paper outlines the challenges in measurement of residual stresses using neutron diffraction in fabricated high strength steel square tubes. The residual stress line scans and maps were measured using the Kowari Strain Scanner located at the Australian Nuclear and Science Organisation (ANSTO) in Australia.

Abstract: Geopolymer concrete (GPC) is attracting increasing attention due to its potential to replace ordinary Portland cement (OPC) concrete to reduce the carbon dioxide emissions from cement production. Although extensive research has been conducted in this area since the 1970s, its applications in engineering practice are still very limited. This paper briefly reviews the recent developments of GPC and its properties at ambient and elevated temperatures. It was found that GPC generally exhibits comparative properties to OPC concrete at ambient temperature. In contrast, GPC often has better fire performance and superior durability. Therefore, GPC could be advantageously used to improve the fire performance and durability of buildings and infrastructure. While a lot of aluminosilicate raw materials (such as fly ash) are low cost, the prohibitive costs of laboratory grade activators (such as sodium hydroxide and sodium silicate) greatly limit the widespread application of GPC. Therefore, there is a need to develop low-cost geopolymer concrete. Meanwhile, a few other challenges should also be overcome, such as difficulties to achieve consistent properties and to control efflorescence of GPC. Further research is required at both material and structural levels to address these issues. Particularly, there is a need to develop relevant building codes to promote the use of GPC in practice.

Abstract: While there is abundant research on fibre reinforced polymer (FRP)-confined circular concrete columns, information on FRP-confined rectangular concrete columns is much more limited. This paper thus presents the axial compression test results of carbon fibre reinforced polymer (CFRP)-confined concrete short columns with rectangular cross-sections. The parameters considered in this study were (a) the concrete strength (b) the cross-sectional aspect ratio (d) the number of CFRP layers and (d) the corner radius. Five existing design-oriented models were used to predict the stress–strain curves of the test specimens with an aim to verify their accuracy. Considerable deviations were found between various model predictions.

Abstract: The objective of this paper is to investigate the performance of slender square reinforced concrete (RC) columns strengthened with carbon fibre reinforced polymer (CFRP) jackets subjected to eccentric loading. Tests were conducted on eight RC columns strengthened with CFRP jackets, and another eight unstrengthened ones served as reference specimens. The main variables explored in this test programme include: (a) load eccentricity (0–150 mm) (b) with or without CFRP strengthening and (c) CFRP configuration (unidirectional and bidirectional). Compared to those unstrengthened RC specimens, the test results showed that no obvious strength increase was observed for specimens confined by unidirectional CFRP jackets, while an increase of 22·8–61·8% was obtained for those strengthened by bidirectional CFRP jackets. The longitudinal fibres were effective in enhancing load-carrying capacity of slender RC columns subjected to eccentric loading.

Abstract: Circular concrete-encased concrete-filled steel tube (CFST) consists of the circular inner CFST and circular outer reinforced concrete. In this paper, the axial compressive behaviour of the composite column is experimentally and analytically investigated. Ten concrete-encased CFST specimens, four reference CFST specimens and two reference reinforced concrete specimens were tested the parameters include the ratio of the steel tube diameter to the column diameter and the concrete strength. The influence of these parameters on the axial load in relation to axial strain, ultimate compressive strength and ductility is discussed. A finite-element model is established, where a stress against strain model is suggested for the concrete confined by circular stirrups located outside the steel tube. The predictions are verified against the test results of the stub columns. Analysis is then performed to investigate the internal force distribution and stress development during the loading process. Parametric analysis is conducted to discover the influence of critical parameters. Finally, simplified superposition methods are suggested to predict the ultimate compressive strength.

Abstract: The global coal industry yields a vast amount of tailings waste, and the utilisation of these tailings necessitates innovative efforts contributing to the United Nations Sustainable Development Goals. One of such novel initiatives is to reuse coal tailings (CT) safely, ecofriendly, and cost-effectively in agroecosystems as a soil conditioner to enhance the productivity of lands. This study aimed to evaluate the potential utilisation of coal tailings waste in the soil amelioration to improve plant performance. The physico–chemical characteristics of coal tailings from two Australian mining sites (CT1 and CT2) showed that the tailings s les are alkaline with loamy and loamy sand textures, respectively. The tailings have ~ 3% of macronutrients, high carbon (C), and low heavy metals and metalloids (As, Cd, Se, Cu, Zn, and Pb). The germination rate of tomato seeds was improved in the low-rate CT treatment. Greenhouse tomato plants exhibited an increase in leaf’s K, Ca, and Mg contents in CT1 and CT2 treatments. More importantly, the CT treatment-induced accumulation of heavy metals in plants was mostly insignificant in both CT treatments. Therefore, we highlight the potential application of coal tailings as a soil conditioner because of the beneficial effect of improved carbon and nutrients (N, P, K, Mg, and Ca) in tomato leaves. Further amendment of the coal tailings should focus on the adjustment of pH and the addition of other beneficial materials for the improvement of soil properties for crops in both the greenhouse and the field.

Abstract: Epithelial ovarian cancer is the fourth leading cause of cancer death among women. Due to the asymptomatic nature and poor survival characteristic of the disease, screening for specific biomarkers for ovarian cancer is a major health priority. Differentially expressed proteins in the serum of ovarian cancer patients have the potential to be used as cancer-specific biomarkers. In this study, proteomic methods were used to screen 24 serum s les from women with high-grade ovarian cancer and compared to a control group of 11 healthy women. Affigel-Blue treated serum s les were processed either by linear (pH 4-7) or narrow range (pH 5.5-6.7) IEF strips for the first dimension. Proteins separated in first dimension were resolved by 8-16% gradient SDS-PAGE. Protein spots were visualized by SYPRO Ruby staining, imaged by FX-imager and compared and analyzed by PDQuest software. Twenty-two protein spots were consistently differentially expressed between normal and ovarian cancer patients by resolving proteins in a linear pH strip of 4-7 for the first dimension. Six of the protein spots, significantly up-regulated in grade 3 ovarian cancer patients (p < 0.05), were identified by MALDI-TOF MS and Western blotting as the isoforms of haptoglobin precursor. When serum proteins were resolved on narrow pH range strips (5.5-6.7), 23 spots were consistently differentially expressed between normal and grade 3 ovarian cancer patients. Of these, 4 protein spots significantly down regulated in grade 3 ovarian cancer patients (p < 0.05) were identified by MALDI-TOF MS and Western blotting, as isoforms of transferrin precursor. Increased expression of serum haptoglobin and transferrin was also identified in peritoneal tumor fluid obtained from women diagnosed with grade 2/3 ovarian cancer (n = 7). Changes in the expression of haptoglobin and transferrin in the serum of women with different pathological grades of ovarian cancer was examined by one-dimensional Western blotting method. Serum s les collected from women suffering from benign, borderline, grade 1, grade 2 and grade 3 cancer (n = 4 for haptoglobin and n = 5 for transferrin in each group) were analyzed and compared to the serum of normal healthy women. The mean serum haptoglobin expression in grade 3 ovarian cancer patients was fourfold higher than in the control subjects (p < 0.05). On the other hand, transferrin expression in grade 3 ovarian cancer patients was decreased by twofold than in normal healthy women (p < 0.05). Haptoglobin expression in the serum of cancer patients (n = 7) decreased following chemotherapy (six cycles of taxol/carboplatin). Concomitant with the decrease of haptoglobin, transferrin expression remained constant in four patients, but increased in three out of seven patients included in the study. Changes in serum expression of haptoglobin correlated with the change of CA 125 levels before and after chemotherapy. In conclusion, proteomic profiling of differentially expressed proteins in the sera of normal women compared to women with ovarian cancer can greatly facilitate the discovery of a panel of biomarkers that may aid in the detection of ovarian cancer with greater specificity.

Abstract: This paper presents the axial compression test results of concrete-filled steel tubular (CFST) stub columns strengthened with carbon fiber reinforced polymer (CFRP) composites. Both circular and rectangular specimens were tested to investigate the retrofitting effects of CFRP composites on them. The test results showed that the CFRP jackets enhanced the load bearing capacity of the circular columns effectively, whereas the enhancement was not so significant for rectangular columns. However, ductility was enhanced to some extent for those rectangular columns. A simple model is proposed to calculate the ultimate strength of circular CFST stub columns wrapped with CFRP. The predicted results are generally in good agreement with the experimental ones obtained in this study and in the literature.

Abstract: The cytokine tumour necrosis factor-alpha (TNF-alpha) has been implicated in the pathogenesis of insulin resistance in Type 2 diabetes mellitus, but limited data are available in relation to gestational diabetes mellitus (GDM), a disease in which similar biochemical abnormalities exist. We investigated the effect of exogenous glucose on the release of TNF-alpha from placental and adipose (omental and subcutaneous) tissue obtained from normal pregnant women, and women with GDM. Human tissue explants were incubated for up to 24 h and TNF-alpha concentration in the incubation medium quantified by ELISA. The effect of normal (5 mmol/l) and high (15 and 25 mmol/l) glucose concentrations on the release of TNF-alpha was assessed. In placental and subcutaneous adipose tissues obtained from women with GDM (n = 6), TNF-alpha release was significantly greater under conditions of high glucose compared with normal glucose (placenta, 25 mmol/l 5915.7 +/- 2579.6 and 15 mmol/l 4547.1 +/- 2039.1 vs. 5 mmol/l 1897.1 +/- 545.5 subcutaneous adipose tissue, 25 mmol/l 423.5 +/- 207.0 and 15 mmol/l 278.5 +/- 138.7 vs. 5 mmol/l 65.3 +/- 28.5 pg/mg protein P < 0.05). In contrast, there was no stimulatory effect of high glucose on TNF-alpha release by tissues obtained from normal pregnant women (n = 6) (placenta, 25 mmol/l 1542.1 +/- 486.2 and 15 mmol/l 4263.3 +/- 2737.7 vs. 5 mmol/l 5422.4 +/- 1599.0 subcutaneous adipose tissue, 25 mmol/l 189.8 +/- 120.4 and 15 mmol/l 124.5 +/- 32.3 vs. 5 mmol/l 217.9 +/- 103.5 pg/mg protein). These observations suggest that tissues from patients with GDM release greater amounts of TNF-alpha in response to high glucose. As TNF-alpha has been previously implicated in the regulation of glucose and lipid metabolism, and of insulin resistance, these data are consistent with the hypothesis that TNF-alpha may be involved in the pathogenesis and/or progression of GDM.
