Summary: The mechanical behavior of concrete-filled steel tubes (CFST) subjected to lateral impact was studied using drop hammer testing and finite element analysis (FEM). The results showed that the maximum stress occurred in the steel tube part and fixed support, while other parts remained in the elastic or elastoplastic stage. The distribution of inertial force in CFST was significantly influenced by impact velocity, while impact mass and cross-sectional steel ratio had no discernible impact.

Summary: This paper conducted lateral impact tests on 10 concrete-filled weathering steel tubular (CFWST) columns and investigated the effect of prestressing on their resistance to lateral impact. The results showed that using pre-stressed cantilever members can significantly improve the impact resistance of the columns. Numerical simulations were also performed to verify the test results and analyze the parameters of the full-scale model. Based on these analyses, empirical formulas for the lateral ultimate displacement and bending moment of the cantilever members were derived. Furthermore, an impact resistance design approach based on the performance of the component was proposed.

Summary: This study aimed to investigate the ultimate seismic performance of thin-walled concrete-filled steel tube (CFST) bridge piers through cyclic loading tests and the establishment of a finite element model. The model accurately reproduced the seismic performance degradation and post-earthquake residual displacement variation by introducing cracks in the concrete and ductile damage in the steel tubes. The analysis showed that the model with concrete cracks reflected the pinching effect of the hysteresis curve and the ductile damage reflected the degradation of bearing capacity and residual displacement under different loading conditions. In addition, the study found that the seismic response of the full in-filled thin-walled CFST bridge pier was the least under the same intensity seismic wave, indicating that the in-filled concrete improved the ultimate seismic capacity. Finally, a formula for the relationship between the residual and maximum displacements under bidirectional seismic waves was established.

Summary: Using steel slag as a substitute for natural aggregates in concrete production can address environmental issues caused by the depletion of natural aggregates and the disposal of slag. The use of steel slag-filled steel tubes enhances the strength and stiffness of the concrete. Experimental results showed that replacing 50% of natural coarse or fine aggregate with steel slag increased compressive strength but decreased flowability. Additionally, SSCFST columns exhibited superior mechanical behavior compared to traditional CFST columns, especially when externally confined.

Summary: To address the issues of river sand shortage and construction waste pollution, this study proposes the use of tailings and recycled aggregate concrete (TRAC) in concrete-filled steel tube (CFT) columns. Six full-scale TRAC filled square steel tube (TRACFST) columns were tested under different loads and verified using finite element method (FEM). The study analyzes the failure mode, hysteresis curves, ductility, energy dissipation capacity, and stiffness degradation based on experimental data. The TRACFST columns exhibit excellent seismic performance with a minor difference in peak bearing capacity and an increase in ductility coefficient with higher RAC substitution rate.

Summary: This paper experimentally investigates the cyclic behavior of steel-reinforced concrete-filled steel tubular (SRCFST) columns. It is found that columns with circular cross-sections exhibit better performance under cyclic loading compared to those with square cross-sections. The steel section type has a negligible influence on seismic behavior, but as the axial load ratio increases, the ductility factor and ultimate load of the columns moderately decrease.

Summary: Piezoelectric single crystal composites (PSCCs) are considered promising candidates for hydrophone applications due to their superior hydrostatic performance, but challenges remain in preparing large-area or conformal PSCCs due to the brittleness and small dimensions of single crystals. A large-area PSCC was successfully prepared using 3D-printing-assisted dice-and-insert technology, showing significant advantages in hydrostatic piezoelectric performance compared to other materials. This breakthrough technology allows for the production of large-scale piezoelectric composites, enhancing the sensitivity of hydrophones significantly.

Summary: Porous PZT-5H single crystals were grown using the solid state crystal growth method. The microstructure, phase structure, and dielectric/piezoelectric properties of [001]-oriented porous PZT-5H single crystal were investigated. In-situ temperature-dependent X-ray diffraction was used to study the evolution of phase structure with temperature. The effect of pores on performance parameters was simulated using COMSOL Multiphysics software. High piezoelectric coefficients d33 and d33* were achieved, with stable behavior under different temperatures. The presence of pores in the single crystal contributed to an extremely large figure of merit g33*d33. This work expands the application possibilities of PZT based single crystals in piezoelectric energy harvesting and actuation at high temperatures.

Summary: The frequency locking phenomenon induced by modal coupling can effectively overcome the dependence of peak frequency on driving strength in nonlinear resonant systems and improve the stability of peak frequency. This study proposes the double frequencies locking phenomenon in a three degrees of freedom (3-DOF) magnetic coupled resonant system driven by piezoelectricity. Experimental and theoretical investigations confirm the occurrence of first frequency locking and the subsequent switching to second frequency locking with the increase of driving force. Furthermore, a mass sensing scheme for double analytes is proposed based on the double frequencies locking phenomenon.
