Abstract

Nine eccentric compression numerical models of GFRP confined reinforced concrete long columns with different eccentric distances were established using finite element analysis software ABAQUS. The influence of eccentric distance on eccentric compression performance of GFRP confined reinforced concrete long columns was investigated based on finite element simulation results. The results show that the increase of the eccentric distance significantly reduces the bending stiffness of the column. The load-midspan deflection curve shows an obvious decline section when load application point is located inside the upper surface of the column. The location of the load application point has a significant influence on the ultimate bearing capacity under eccentric compression of the long column. The ultimate bearing capacity decreases greatly with the increase of eccentric distance, especially when the loading position is gradually eccentric from the axial position to the edge of the column.
