Abstract
In order to analyze the deterioration of mechanical properties of axially compressed reinforced concrete columns under corrosion,a simulation model of reinforced concrete columns was established by ABAQUS finite element software,and the effects of corrosion rate,axial compression ratio,stirrup spacing and longitudinal reinforcement diameter on the shear capacity of rectangular columns were deeply analyzed.The results show that with the increase of axial compression ratio and longitudinal reinforcement diameter,the forward load level of reinforced concrete column increases continuously.With the increase of stirrup spacing and corrosion rate,the forward load bearing level of reinforced concrete column decreases continuously.Therefore,the mechanical properties of reinforced concrete columns can be improved by increasing axial compression ratio and longitudinal reinforcement diameter,reducing stirrup spacing and corrosion rate.关键词
