| description | This paper presents a numerical simulation and theoretical analysis of the eccentric compressive performance of a novel composite concrete-filled steel tube (CFST) latticed column with corrugated steel plates for industrial buildings. The influence of multiple parameters was systematically examined, encompassing the eccentricity ratio, material strengths (steel tube and concrete), corrugated steel plate waveform, and steel lacing tube strength. The results show that eccentric loading causes typical bending failure, with corrugated steel plates providing significant restraining effects, and diagonal lacing tubes optimizing load distribution and bending resistance. Increased eccentricity reduces the load capacity by up to 41.8% but improves the ductility by 50.6%, with benefits ceasing beyond 350 mm of eccentricity. A higher steel strength enhances the load capacity (28.6%) and ductility (14.5%), while a higher concrete strength improves the capacity but reduces the ductility. Longer waveforms in corrugated steel plates improve the stress redistribution, enhancing both capacity (19.1%) and ductility (9.7%). The eccentric compression modification formulas proposed in this study for the latticed column show a reliable calculation accuracy within 11% of simulations. |
