ABSTRACT
Because of chloride ion and long expected service life, concrete structures in corrosion environment will suffer to corrosion damage, leading to deterioration of seismic performance. A total of eight RC pier column specimens were experimentally investigated for the influence of steel corrosion and axial repeated loads on the seismic performance of RC column. A parametric study by finite element analysis is conducted to assess the effect of primary parameters on the seismic performance of columns, such as concrete strength and longitudinal reinforcement ratio. Pier was simplified as a cantilever. The fiber finite element model of pier was shown in figure 1. The fiber finite element model of piers. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315207681/cd556cd4-4dcf-4efe-8e29-56fc67b8bfbd/content/fig289_1.tif"/>
