Abstract：H-shaped steel was used as the connection node,and the form of the post-poured section stirrups and the eccentricity were taken as parameters.Axial eccentric compression tests were conducted on high-titanium slag concrete assembled columns and cast-in-place columns to study the mechanical properties of their longitudinal reinforcement.The results show that under small and large eccentric loads,the stress characteristics and failure modes of the assembled columns are basically the same as those of the cast-in-place columns.The measured and calculated ultimate bearing capacities of the assembled columns and cast-in-place columns are very close.For the assembled columns,using spiral stirrups in the post-poured section can increase their ultimate bearing capacity.
