Abstract

Abstract

Ultra-high toughness cementitious composites （UHTCC） are fiber-reinforced， cement-based materials known for their exceptional toughness， crack resistance， and tensile strain hardening. These properties ensure that UHTCC resists cracking under normal conditions and effectively prevents the intrusion of chloride ions and water， thereby enhancing structural durability and energy dissipation. As a result， UHTCC holds significant potential for use in critical projects and key infrastructure. This study introduces a UHTCC-encased circular steel tube composite column， offering advantages such as lightweight construction， ease of assembly， high bearing capacity， and superior durability. The axial compressive performance and steel tube buckling behavior of the proposed composite column， which incorporates both stud and PBL shear connectors， were investigated using a combined approach of theoretical and finite element analysis.A detailed finite element model of the composite column was developed and validated against experimental data， with an error range of 1.2%–2.3%. The finite element parameter analysis showed that as the number of PBLs increased from 4 to 12， the bearing capacity of the composite column with width-to-thickness ratios of 25 and 150 increased by 15% and 10%， respectively. Finally， theoretical calculations were performed to determine the steel tube’s critical buckling load， from which the composite column’s axial compressive capacity was derived.
