Summary: Replacing GFRP bars with SS bars in concrete columns can effectively solve corrosion problems in harsh environments. The research studied the eccentric compression behavior of SSC columns reinforced with GFRP and SS bars and analyzed the effect of reinforcement stiffness on the N-M interaction diagrams. The results showed that replacing GFRP bars with SS bars improved the ductility of the columns, and the failure mode was influenced by the axial stiffness of the reinforcement.

Summary: In this study, full iron tailings concrete (FITC) was created using iron tailings from a tailings pond in Qian'an, China. Eight rectangular reinforced concrete (RC) columns with conventional reinforced concrete (CRC) as a control were tested to investigate the effects of section dimensions, initial eccentricities, and concrete strengths, on the structural behaviour of FITRC columns under large eccentric short-term loading. The experimental and analytical results indicated that the FITRC columns exhibited slightly lower cracking load and lower ultimate load capacity than the CRC columns, but still satisfied the code requirements.

Summary: In the study, twelve full-scale reinforced concrete beams with two tension lap splices were constructed and tested under a four-point loading test. The results showed that beams with shorter lap splices failed by bond loss between steel and concrete at the lap splice region, while beams with longer lap splices failed by rebar yielding and exhibited ductile behavior. Strain distribution in the lap splice region was investigated, revealing stress concentration at the loaded end of the lap splice.

Summary: This study analyzes the dual convection regime in a Y shaped porous enclosure with heat and mass distribution, using a mathematical model and a finite element method. Key parameters such as the Hartmann number, Lewis number, Rayleigh number, and buoyancy ratio are evaluated for their impact on the flow, heat transfer rate, and mass transfer rate. The results show that an increase in these parameters amplifies both mass and heat transfer rates. The buoyancy ratio has a significant impact on the flow and transfer rates, with a greater influence seen for a buoyancy ratio of 2.

Summary: The dynamics of chemotaxis mechanism for bioconvection in the swirling movement of a flexible heated cylinder with a combination of constant rotation and axial stretching is investigated. The study considers a non-linear viscoelastic fluid with time relaxation and the presence of gyrotactic micro-species. The impact of thermal and concentration gradients on solutal and thermal transportation is analyzed using the Soret-Dufour theory, and an external magnetic field is applied as a constraint. The non-linear differential equations that govern the problem are solved using the bvp5c function, and the results are presented graphically and explained in terms of practical implementation. Each result demonstrates the influence of dimensionless parameters on flow, energy, and bioconvection phenomena, showing that fluid temperature increases due to the preventing solutal deposition and coolant effect caused by Soret and Dufour effects.
