What is CFST Arch Bridge Defects Analysis about?

This study investigates the strength of concrete-filled steel tube (CFST) ribs with defects, focusing on the effects of cap gaps and spiral-welded seam strength under weak eccentric axial compression. Using finite element analysis with ABAQUS, the research reveals that while spiral-welded seam defects have a lesser impact on the bearing capacity of CFST compared to empty steel tubes, they significantly affect local yield failure modes. The findings provide insights into the performance of CFSTs with composi
