2. BIBLIOMETRIC ANALYSIS METHOD
1.INTRODUCTION Concrete-filled steel tubes (CFST) stand as prominent components in structural engineering, acclaimed for their heightened load-bearing capacity, durability, remarkable fire resistance, and seismic stability, as attested by[1]. The amalgamation of steel tubes and concrete cores not only mitigates inherent concrete brittleness but also augments damping resistance, as elucidated by [2]. CFSTs find extensive application as load-bearing columns in tall structures, showcasing exceptional resilience to compressive stresses and ductility. The nuanced interaction between steel tubes and concrete, especially during post-buckling phases, necessitates a departure from presumptions of homogenous cross-sections, prompting a more accurate conceptualization of CFST as composite entities rather than uniform structures, an assertion supported by [3]. Local buckling intricacies, influenced by concrete constraints, significantly impact CFST behavior under compression, revealing a complex interplay between buckling strain, residual strength, and steel tube deformation properties [4].Disparities arising from the differential Poisson’s ratio between steel tubes and concrete within the elastic range lead to gradual compressive stress growth, delaying the emergence of confining stress in CFST steel tubes, particularly evident in thin-walled and high© 2024, IRJET

strength concrete configurations[5]. Many studies showed that the stiffness of CFST columns made of high-strength concrete rapidly decreased during the initial post-buckling period[6]. The limitations of modeling CFST concrete cores using the constrained mechanical model of steel tube confined concrete stub columns (STCCs) are underscored. Eurocode 4's composite element theory, explored by scholars like[7], emerges as a pivotal framework, demanding the amalgamation of individual axial capacities of steel tubes and concrete cores to ascertain the axial load-bearing capability of CFST columns. This study addresses the qualitative and subjective nature of manual-based reviews by employing bibliometric and qualitative analyses, ensuring an objective and accurate examination of research articles in the CFST field from 2019 to 2023. The ensuing sections delve into the intricacies of bibliometric methodologies, offering a comprehensive exploration of academic contributions, discernible research trajectories, and prevailing trends in the specialized domain of stiffened CFST stud columns, fostering a nuanced understanding of information dynamics, research impacts, and broader influences shaping the field.

The bibliometric analysis method under consideration involves a comprehensive scrutiny and interpretation of data acquired through bibliometric techniques, surpassing mere numerical analysis to unveil profound insights into underlying patterns, relationships, and trends within the research landscape. In addition to numerical assessments, qualitative analysis is applied, wherein researchers meticulously examine and interpret qualitative facets of bibliometric data, including publication content, citation context, and emergent themes and concepts in the literature. This qualitative analysis employs research methods such as content analysis, thematic analysis, and discourse analysis to reveal latent meanings and nuances in the data. Conducting a qualitative analysis of bibliometric data allows researchers to gain insights into research topics, theoretical frameworks, methodological approaches, and conceptual developments within a specific field. It facilitates the identification of emerging research trends, exploration of interconnections between different studies, and comprehension of the intellectual structure of a research domain. Moreover, qualitative analysis of bibliometric methods aids in identifying research gaps, challenges, and opportunities, providing a nuanced understanding of the research landscape and paving the way for the identification of new ISO 9001:2008 Certified Journal
