Mechanical Behavior Analysis of Reinforced Concrete Column Strengthening with Shear Wall

Abstract:

This paper studies the influences of factors such as axial compressive ratio and shear wall thickness on the mechanical performance of the reinforced concrete column strengthening with shear wall under low-cyclic reversed loading. Considering the secondary stress characteristics of the strengthening column, a numerical analysis was made on the load displacement hysteretic curve and skeleton curve. The results show that, with the increasing of axial compression ratio, the bearing capacity and stiffness of reinforced concrete column increased, but the ductility of reinforced column reduced; the bearing capacity and rigidity of reinforced column strengthening with shear wall increase while the ductile was lower; the change of shear wall thickness has a little effect on the bearing capacity, but improves the energy dissipation capacity of reinforced concrete columns.
