Structural mechanism-based intelligent capacity prediction methods for concrete-encased CFST columns

Xiao-Guang Zhou et al.

Summary: This study proposes an innovative framework that combines data-driven models with physical mechanisms to estimate the axial compression capacity of concrete-encased CFST. The results demonstrate that all models developed through this method perform well and reflect structural mechanisms to a fair extent.

Performance of concrete-encased CFST column-to-beam 3-D joints under seismic loading: Analysis

Wei Li et al.

Summary: A numerical model of the concrete-encased concrete-filled steel tubular column to steel beam joint was established and verified by experimental results. The stress and force distributions of different components under different loading phases were analyzed and compared between planar and 3-D joints. Parametric studies were conducted to reveal the effects of key parameters, and strength prediction models and hysteretic models were proposed.

Experimental and numerical studies of concrete-encased concrete-filled steel tube stub columns under uniaxial and biaxial eccentric compression

You-Xin Ma et al.

Summary: Experimental and numerical studies were conducted to investigate the structural performance and resistances of concrete-encased concrete-filled steel tube (CECFST) stub columns under different loading conditions. It was found that loading eccentricity and end moment ratio affect the ductility and failure mode of the specimen, leading to the proposal of new design methods to improve design accuracy.

Study on axial compressive stiffness of RAC-encased RACFST composite columns

Cai Min et al.

Summary: This study investigated the axial compressive stiffness of the recycled aggregate concrete (RAC)-encased recycled aggregate concrete-filled steel tube (RACFST) composite columns with 24 specimens. The interaction of each component of the composite column was analyzed, and constitutive models were discussed for different layers of the composite column. Simple formulas were proposed to calculate the axial compressive stiffness of the composite columns, which can help engineers predict the axial deformation of structures in high-rise buildings more accurately.

Circular concrete filled thin-walled steel tubes under pure torsion: Experiments

Khanh Ba Le et al.

Summary: This study experimentally investigated the torsional behavior of various specimens, finding that concrete infill enhances the torsional moment capacity of concrete filled steel tube specimens. The presence of diagonal cracks on the concrete infill after cutting the steel tubes provides evidence of collaboration between the steel tube and concrete.
