Abstract

In order to establish a trilinear skeleton curve model of RC columns considering stirrup corrosion, accelerated corrosion tests were carried out on 8 inverted T-shaped RC columns, and then low-cycle reciprocating load tests were carried out. The influence of stirrup corrosion on the seismic performance of RC columns is analyzed by comparing the factors such as different stirrup spacing and corrosion rate. Combined with the characteristic point parameters of the skeleton curve of the uncorroded RC column, a three-line skeleton curve characteristic point calculation model suitable for the corroded RC column is obtained. The calculation results are compared with the experimental data, and the basic error range is within 6%, indicating that the fitting formula has great accuracy.
