Abstract :

The assessment of the strength of welded Circular Hollow Section (CHS) steel tubular joints is of paramount importance in the safe design of engineered structures. In order to address this core factor, this paper employs Gaussian Process Regression (GPR), a probabilistic machine learning method based on a collected database, with the objective of modelling and predicting the strength of three types of welded CHS steel tubular joints and effectively quantifying their associated uncertainties. This study presents two strength prediction models for welded CHS steel tubular joints: a Single-Output Gaussian Process Regression (SOGPR) model and a Multi-task Gaussian Process Regression (MTGPR) model. The models are evaluated and compared with existing empirical approaches, design guides, non-probabilistic machine learning methods, and Bayesian Linear Regression. The objective is to demonstrate the accuracy and high efficiency of the predictions made by these models. Furthermore, the MTGPR model employs the shared information between the three types of joints to enhance the prediction performance. Subsequently, the SHapley Additive exPlanations method was employed to examine the interpretability of the GPR model in relation to the strength uncertainty of welded CHS steel tubular joints. Ultimately, the uncertainty in the strength of the three welded CHS steel tubular joints is quantified based on the proposed prediction methodology in conjunction with Monte Carlo Simulation through the utilisation of Sobol sensitivity analysis and Morris sensitivity analysis. The findings indicate that the chord diameter D and chord length L of welded CHS steel tubular joints have the greatest impact on the uncertainty of strength. The aforementioned study facilitates the optimisation of the design of actual engineering structures, the management of the range of strength uncertainty and the enhancement of the safety and reliability of engineering structures.

Abstract :

3-mercaptopropyltriethoxysilane (KH580) surface organic layered double hydroxides (LDHs) was synthesized to simultaneously bolster the anti-ageing property of SBS copolymer modified bitumen (SMB). The X-ray diffraction and X-ray photoelectron spectroscopy proved that the KH580 was successfully grafted on the surface of LDHs (KH-LDHs). After KH580 surface organic modification, the aggregation and hydrophilicity of LDHs were significantly restrained, and the UV absorbing capacity was concurrently enhanced. Compared with LDHs, KHLDHs exhibited superior compatibility within SMB and could improve the high-temperature performance and elastic behavior of SMB much better. After ageing, SMB became stiff and crisp, the rheological properties worsened, and the number of oxygen-containing groups (C--O and S--O) in SMB experienced a considerable rise. Simultaneously, SBS copolymer also degraded during the ageing process, further deteriorating the performance of SMB. LDHs was able to inhibit the ageing repercussions on the rheological properties, chemical structure and SBS copolymer, thus bolstering both the anti-ageing property of SMB and the degradation resistance of SBS copolymer. Furthermore, the role of LDHs would be dramatically strengthened by KH580 surface organic modification.

Abstract :

To reduce the consumption of Ordinary Portland Cement (OPC) in subgrade reinforcement, steel slag (SS) and calcium carbide residual (CCR) were applied to solidify undesirable soil. The relationship between the unconfined compressive strength of solidified soil and OPC, SS, CCR was analysed by response surface method. The result showed that SS and CCR exhibited synergistic enhancement on the strength of solidified soil. Compared with OPC solidified soil, the introduction of 11 % SS and 6.5 % CCR could reduce 4 % OPC at the same strength. OPC/SS/CCR solidified soil could reduce cement consumption and recycle industrial solid wastes, which was conducive to reducing carbon emissions and protecting ecological environment. Then, the interaction mechanism of SS and CCR on the strength of solidified soil was thoroughly investigated by crystal structure, chemical composition and micro-structural morphology. CCR increased the alkalinity of soil and SS provided silica-aluminum oxides, these two solid wastes synergistically promoted the hydration reaction. Compared with original and OPC solidified soil, newly produced AFt (3CaOAl2O33CaSO(4)32 H2O), more C-S-H (CaOSiO22 H2O) and calcite were found in OPC/SS/CCR solidified soil. These hydration products could fill the deleterious (extra-large pores (>20 mu m) and large pores (5-20 mu m)) in soil, reduce the porosity and enhance the compactness, which achieved a significant increase in the strength of solidified soil.

Abstract&Keyword Cite Version(2)

Abstract :

gamma- aminopropyltriethoxy silane organic layered double hydroxides (LDHs) and SBS were combined into LDHs/SBS composite to improve anti-ageing performance of SBS modified bitumen (SMB). XPS and SEM showed that organic LDHs (OLDHs) was successfully grafted onto SBS, and OLDHs could be more evenly distributed in SBS, which was conducive to improve the anti-degradation capability of SBS. Compared with SBS and LDHs/SBS composite, the interaction between OLDHs/SBS composite and bitumen was stronger, resulting in the better stabilization of SBS and LDHs in bitumen. Furthermore, OLDHs/SBS composite could enhance the hightemperature property of SMB. SMB became hard and brittle during ageing, the physical and rheological properties were remarkably deteriorated. LDHs/SBS and OLDHs/SBS composite could alleviate the damage of ageing on the highand low-temperature performance of SMB and enhance the anti-ageing capacity, particularly OLDHs/SBS composite. Then, the improvement mechanism of OLDHs/SBS and LDHs/SBS composite on the anti- ageing capability of SMB was analyzed at microscopic scale. LDHs/SBS and OLDHs/SBS composite could hinder the infiltration of oxygen into bitumen and decrease the oxygen content, and simultaneously decelerate the oxygen diffusion rate in bitumen. The synergistic combination of these two functions conspicuously diminished the probability of oxygen colliding with bitumen or SBS, which relieved the ageing of bitumen and the degradation of SBS, and ultimately improved the anti-ageing capability of SMB. Furthermore, due to the better stability, the effectiveness of OLDHs/SBS composite was more notable than LDHs/SBS composite, OLDHs/SBS composite demonstrated superior improvement on the anti-ageing capability of SMB than LDHs/SBS composite.

Abstract&Keyword Cite Version(2)

Abstract :

SBS modified bitumen (SMB) is widely used for its excellent physical and rheological properties, but it is susceptible to aging due to exposure to environmental factors such as heat, light, and oxygen. This aging process involves bitumen aging and SBS degradation, which complicates the rejuvenation of SMB. In order to explore the rejuvenation mechanism of aged SMB, particularly emphasizing the rejuvenation effects of epoxy compounds (BUDGE, TMPGE, and RDGE), a combination of molecular dynamics simulation and experiments was employed. The thermodynamic, chemical, and physical properties of rejuvenated SMB were analyzed. Results show that BUDGE and its repaired SBS exhibit excellent flexibility compared to TMPGE, improving cohesive energy density and free volume of aged bitumen, which facilitates recovery of ductility in aged SMB. Conversely, SBS repaired with RDGE increases cohesive energy density of aged SMB while reducing free volume, which enhances stiffness of bitumen. Additionally, rigid groups in RDGE inhibit mobility of both itself and the repaired SBS, leading to a reduction in the ductility of aged SMB to 10.1 cm. Besides, SBS repaired with RDGE shows strongest binding with resins and aromatics, which diminishes lubricating effect of these components on asphaltenes. This reduction in lubrication enhances aggregation of asphaltenes, ultimately raising flow resistance.

Abstract :

The thermal-oxidative aging of asphalt is extensively researched in recent years. However, the aging behavior of asphalt in salt and water environment receives less attention. A virgin asphalt binder was treated by various coupling conditions of salt and water in this work aiming at understanding the aging behaviors, and then the physical indexes, rheological parameters, chemical structures, four fractions and contact angles of asphalt before and after aging were measured to evaluated the effects of different aging environments on the physicochemical properties of asphalt. Results indicate that the aged asphalt has higher softening point and complex modulus while lower penetration and phase angle in comparison with unaged asphalt, implying the asphalt becomes harder and more brittle after aging. Although asphalt aged in salt and water conditions exhibits similar changes in macro-properties to thermal-oxidative aged asphalt, the analysis of chemical composition indicates that the aging of asphalt under salt and water environment is caused by unique inducements, which can be divided into two parts, that is, separating out of aromatics and saturates from asphalt by combined action of salt out and emulsification, and increasing of asphaltenes and resins caused by oxidation. These two factors work together leading to the change of colloidal structure and finally cause the deteriorate of macro-properties. Besides, the results of contact angle test indicate the increasing polar functional groups resulting from aging enhance hydrophily of asphalt and increase the possibility of water to enter the interior of asphalt, exacerbating the performance degradation of asphalt.

Abstract :

SBS modified asphalt (SBSMA) pavements have gained popularity worldwide due to their prominent performance. However, its maintenance and reconstruction projects will produce a large amount of reclaimed asphalt pavement (RAP) during the long-term service of asphalt pavement. Adding rejuvenators products is a common method to recycling RAP. However, conventional rejuvenators are typical component regulators applicable to recycling unmodified asphalt, while there is a poor regeneration effect for the aged SBS modified asphalt (ASBSMA), because it cannot repair the degraded SBS polymer. Fortunately, reactive rejuvenator (RR) has achieved this breakthrough based on the research findings in recent years. It contains special compounds that have the ability to repair the degraded SBS. The vital questions to be investigated in the present review are how the four current systems of RR (epoxy system, isocyanate system, compound system and polymer system) affect ASBSMA's properties and how well does its regeneration effect. Existing research indicated that RRs are favorable for the regeneration of A-SBSMA and have their respective characteristics. This review summaries various RR different regeneration mechanism, and analyzed its effects on physical properties, rheological properties, high and low temperature properties, and microscopic characteristics of A-SBSMA. Although research on RR is still in its infancy with a limited number of relevant studies, they show an excellent regeneration effect for A-SBSMA and hold a promising prospect. Overall, this review provides information on the feasibility of using RR as a sustainable SBSMA rejuvenator to promote conserving resources and reusing RAP.

Abstract :

To promote the anti-ageing performance of asphalt, layered double hydroxides (LDHs) modified by propyl trimethoxylsilane (MPMS) was prepared and applied to modify asphalt. Fourier transform infrared spectroscopy (FTIR) showed that MPMS was chemically-grafted on the surface of LDHs. The interaction between LDHs and asphalt was significantly enhanced after MPMS organic modification, and MPMS organic LDHs (OMLDHs) exhibited better compatibility in asphalt. OMLDHs and LDHs could enhance the high-temperature properties of asphalt, particularly OMLDHs. After ageing, the properties and structure of asphalt were dramatically degenerated. The incorporation of LDHs could inhibit the oxygenic groups increase in asphalt molecules during ageing, and retard the gelatinization of colloidal structures. LDHs could alleviate the negative effect of ageing on asphalt, and improve the anti-ageing performance of asphalt. The improvement effectiveness of LDHs on the anti-ageing performance of asphalt was remarkably improved after MPMS modification.

Abstract :

Assessing the seismic capacity of pier columns is a crucial element in the performance -based seismic design of bridges. Such assessment necessitates a probabilistic approach to accurately determine the marginal probability distributions of seismic capacities and to characterize the dependencies among these variables. In response to this need, this paper employs Multi -Output Gaussian Process Regression (MO-GPR), a probabilistic machine learning method, to jointly model the multiple seismic capacities of pier columns. We initially introduce a probabilistic seismic capacity model that utilizes MO-GPR for pier columns and validate its predictive accuracy in comparison to Bayesian linear regression and existing empirical methods. Subsequently, the methodology is augmented by the integration of hierarchical modeling within the MO-GPR framework, resulting in a Multi -Output Hierarchical Gaussian Process Regression (MO-HGPR) model that effectively estimates intraclass correlation coefficients for specific types of datasets. It is postulated that these correlation coefficients also reflect correlations associated with multiple components of the real structure. This study employs MO-HGPR and MO-GPR separately to investigate the potential correlations of seismic capacities among pier columns and distinct limit states. The results demonstrate that the MO-GPR model exhibits superior prediction accuracy and more effectively portrays uncertainty compared to existing empirical models. Moreover, the correlations of seismic capacities among piers and limit states are both robust and significantly impact the seismic fragility of bridges. This finding highlights the essential nature of considering capacities correlations in seismic fragility or risk assessment processes.

Abstract :

The cinnamic acid intercalated layered double hydroxides (CA-LDHs) were prepared by anion exchange method and analyzed by X-ray diffractometer (XRD) Fourier transform infrared (FTIR) spectrometer, scanning electron microscopy (SEM), contact angle goniometer, ultraviolet and visible (UV-vis) spectroscopy, and thermogravimetric (TG) analysis system. Then, the CA-LDHs were added to styrene-butadiene-styrene (SBS) modified bitumen together with an antioxidant composed of octadecyl-3-(3,5di-tert-butyl-4-hydroxyphenyl)-propionate (1076) and tris(2,4-di-tert-butylphenyl) phosphite (168) at a mass ratio of 1 : 1. The effects of antioxidant/CA-LDHs on the physical and rheological properties and chemical composition and characteristics of SBS-modified bitumen before and after pressurized aging vessel (PAV) and ultraviolet (UV) aging were investigated. The results revealed that CA was successfully intercalated into the interlayer space of LDHs. Meanwhile, the CA-LDHs performed improved hydrophobicity and UV absorption capacity compared with LDHs, resulting in enhanced compatibility of LDHs with SBS-modified bitumen, and then the antiaging properties of SBS-modified bitumen could be further strengthened, especially the anti-UV aging properties. Moreover, the mixture of antioxidants and CA-LDHs could synergistically improve the SBS-modified bitumen's thermal- and photo-oxidative aging resistance.
