Abstract

Abstract

The friction energy-dissipating column base， as a novel form of seismic construction in steel structures， has a significant impact on the mechanical properties of structures. To investigate its flexural performance， five such column base specimens were analyzed under monotonic horizontal loading using the finite element software ABAQUS. The study examined the flexural performance， the composition of the flexural capacity， and the calculation methods for these column bases. A theoretical formula for predicting the flexural capacity of friction energy-dissipating column bases was proposed. The variation in bearing capacity under monotonic horizontal displacement loading was analyzed and compared with the theoretical formula for verification. The results showed that under monotonic horizontal loading， all column base models exhibited semi-rigid behavior， with damage primarily distributed in secondary components. This allowed the column base to fully utilize its frictional performance， thereby reducing damage to the main structure. The unified theoretical formula for the flexural capacity of friction energy-dissipating column bases can accurately predict the flexural capacity of the five types of column bases， providing a valuable reference for their application in practical engineering.
