Study of the Axial Compressive Behaviour of Cross-Shaped CFST and ST Columns with Inner Changes
Buildings, 2023 In this study, novel cross-shaped concrete-filled steel tube (CFST) and steel tube (ST) columns were developed. CFST columns have a high load-carrying capacity and excellent performance under seismic conditions, and the construction process is fast.
