Abstract:

This paper presents an experimental study on the V-shape concrete-filled steel tube (CFST) laced column. The test parameters are column slenderness and eccentricity. The deformation process, failure modes and strains of specimens on the longitudinal chords and diagonal lacing are analyzed. The failure characteristic of a specimen on whole and local, failure mechanism and ultimate load carrying capacity of the CFST laced column are studied. Test results show that axial force and bending moment are dominate forces on lacing bars of the specimens unlike axial force in lacing bars in the laced column with transverse struts, and strains of lacing bar are much larger than that of the latter. There is differential axially force between longitudinal chords. With the increase of slenderness the column behavior shifts towards global stability from local buckling. The load bearing capacities for single chord of stub column should be checked in calculation. Based on the analysis of experimental results, the calculating method is presented for eccentricity reduction coefficient and stability coefficient. Finally the calculating formula of the V-shape lacing CFST laced column ultimate load carrying capacity is presented.
