Abstract

In order to study the seismic performance of RAC column silica fume enhanced, this paper selects 1 common RAC column as the control group, and the 3 column contains 4%, 6% RAC and 8% silica fume as the experimental group, combined with ABAQUS finite element simulation, the RAC column broken ring model, skeleton curve, bearing capacity and ductility, energy dissipation and damage stiffness degradation properties were analyzed. The results show that the finite element simulation results and test results of composite is better, its failure forms are from the column began to crack, and gradually expand upward, until the last column began to appear concrete damage, shedding in doped silica fume content; 6%, is conducive to the improvement of seismic performance the RAC column, but with the increase of silicon content, the lower the ductility of the column, the energy dissipation capacity weakened, stiffness and strength degradation speed.
