Special Issue Information

Dear Colleagues,

Since the advent of Portland cement in 1824, cement-based materials have become the most extensively utilized and consumed building material. However, although the durability of concrete has a great impact on the safety and usability of the structure, compressive strength is still recognized as an extremely important property and significantly affects the structural performance of a building. Compressive strength is the first factor to be considered in structural design and quality inspection. A correct understanding of the mechanism and factors that affect strength is of great significance to the accurate design of concrete and ensuring the quality of the structure. In structural design, it is the first factor to be considered during quality inspection. Thus, this Special Issue focuses on advances in the compressive strength of cement-based materials. The purpose of this Special Issue is to provide a platform for communication between the government, construction companies, research institutes, and university researchers on the strength of cement-based materials. We welcome the submission of scientific works addressing the compressive strength of concrete, such as strengthening mechanisms, strength modeling and prediction, ultimate strength, and improvement techniques (not limited to the above topics).

This study investigates the flexural performance of desert sand concrete-filled steel tube (DS-CFST) members through experimental validation and finite element modeling (FEM). An extensive database of square and circular CFST specimens subjected to pure bending was analyzed to validate an ABAQUS-based FEM. Parametric studies evaluated the influence of steel yield strength, steel ratio, stirrup confinement, and desert sand replacement ratio (r) on ultimate bending moment, stiffness, and failure modes. The results indicated that steel yield strength and section geometry significantly affected bending capacity, while desert sand substitution (r ≤ 1) had a negligible impact on capacity, reducing it by less than 3%. The FEM accurately predicted buckling patterns, moment-curvature relationships, and failure modes. New design formulas for predicting ultimate bending moment and flexural stiffness were proposed, demonstrating superior accuracy (mean error < 1%) compared to existing design codes (AIJ, AISC, GB). This study highlights that DS-CFST members, particularly circular sections, offer robust flexural performance, with enhanced ductility and uniform stress distribution. The findings underscore the potential of using desert sand as a sustainable material in concrete-filled steel tube structures without compromising structural integrity. Full article
