Summary: The effects of Eu incorporation in the RbBaPO4 structure were explored through atomistic simulation and crystal field models. The preferred intrinsic defect type was found to be the anti-site defect. It was observed that Eu3+ tends to enter the Ba site as charge compensation in the presence of RbBa' anti-sites. Crystal field theory revealed that substitution of Eu3+ for Ba2+ in the anti-site defect induces a local symmetry distortion of the slightly distorted C4 type. The 7F1 and 7F2 energy sublevels as well as the 7F1 manifold were successfully reproduced using phenomenological charge factors and non-null crystal field parameters.

Summary: Existing long-span truss bridges often require significant retrofits to enhance their resistance against extreme load events, such as seismic loads. However, conventional seismic retrofit measures may not provide sufficient alternative load path redundancy for bridges vulnerable to sudden member-loss scenarios. This paper proposes a performance-based retrofit approach that uses demand-to-capacity ratio or strain ratio as indicators to meet predetermined performance objectives. The retrofit increases the weight of steel by less than 10% and ensures desired performance levels in case of sudden member loss.

Summary: This study focuses on the use of ultrahigh-performance concrete (UHPC) in precast segmental beams to enhance bridge performance and durability. The shear behavior of the dry-jointed segmental beams was investigated through testing various specimens with different joint types and shear span-to-depth ratios. The results showed that shear capacity, stiffness, and cracking load of the dry-jointed segmental beams were lower than those of the monolithic specimen, and the number of shear keys also influenced the shear behavior. The study also evaluated UHPC design codes and proposed a simplified strut-and-tie model for estimating shear strength.

Summary: The ductility of square CFST columns is lower than circular ones, but can be improved by adding internal steel spiral stirrups. High-strength steel (HSS) spirals have a significant effect on the seismic behavior of HSS-CFST columns under high axial load ratio, improving hysteretic behavior and energy dissipation capacity. The addition of spiral pitch and axial load ratio can impact the load-carrying capability and deformation ability of square CFST columns.

Summary: Precast ultra-high-performance concrete (UHPC) segmental bridges (PUSBs) are a competitive bridge type in modern civil engineering. To understand the behavior of PUSBs, seven specimens were fabricated and tested, with different reinforcement, construction methods, joint types, shear span-to-depth ratios, stirrup ratios, and numbers of shear keys. Two failure modes were observed: flexural failure and shear failure. The segmental beams exhibited better ductility and deformation capacity compared to monolithic beams. Stirrups showed a positive effect on cracking control and shear strength. The three-keyed specimen performed better than the single-keyed specimen. Calculation methods were proposed to predict cracking strength and ultimate capacity of PUSBs.

Summary: Externally prestressed ultra-high-performance concrete beams without stirrups are a competitive option in bridge engineering. Five specimens were tested to investigate the shear behavior, considering parameters such as shear span-to-depth ratio, shear stirrups, and reinforcement ratio. The specimens exhibited diagonal tension or flexural failure, and their stiffness and shear strength decreased with increasing shear span-to-depth ratio. Stirrups enhanced shear resistance but resulted in a brittle shear failure mode. A higher reinforcement ratio promoted ductile shear failure. The shear-cracking strength was found to be a significant factor in design, and equations for predicting shear strength were proposed and validated.

Summary: The use of locally available seawater, sea sand, and coral aggregate can shorten construction time and address the shortage of river sand and natural gravel resources for concrete preparation in remote islands or reefs. This study experimentally investigated the shear behavior of seawater sea-sand coral aggregate concrete (SSCAC) beams reinforced with non-corrosive carbon fiber-reinforced polymer (CFRP) strip stirrups. The findings revealed that SSCAC beams reinforced with CFRP exhibited a brittle shear failure mode and had approximately 10% lower shear strength compared to natural aggregate concrete (NAC) beams.

Summary: This study aims to improve the mechanical properties of recycled aggregate concrete (RAC) and achieve its sustainable application by filling it into steel tubes to form recycled aggregate concrete filled steel tubular columns (RA-CFST columns). The concentric and eccentric compression behavior of square RA-CFST columns confined by high-strength steel (HSS) spiral stirrups was experimentally studied. The effects of critical test parameters on the compression behavior of the specimens were examined, and the failure modes, load-deflection responses, strain distributions, ductility, and composite confinement mechanism of the columns were comprehensively studied. Improved design models for predicting the ultimate strength (Nu) of the spiral-confined CFST columns were also suggested.

Summary: During the service period, chloride-induced corrosion (CIC) has a major impact on the performance and durability of aging coastal reinforced concrete (RC) structures. RC columns, which are important vertical members of many long-span highway bridges and high-rise buildings, are susceptible to the effects of non-uniform CIC and intentional or accidental explosive attacks. However, there have been few studies on the time-dependent blast fragilities of deteriorating coastal RC columns exposed to non-uniform CIC.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.
