Abstract

In order to establish a restoring force model considering rusted RC columns with stirrup, 8 inverted T-shaped RC columns were subjected to accelerated corrosion tests, and then to low-cycle reciprocating load tests. In view of the problems of strength decay and stiffness degradation caused by cumulative damage, the cyclic degradation index β i was introduced to establish a restoring force model for RC columns after stirrup corrosion. By comparing the restored force model with the hysteretic curve of the test, the agreement is good, indicating that the restored force model has high accuracy and strong applicability, and can be used to clarify the hysteretic characteristics of RC column after the stirrup corrosion. The research results can provide theoretical basis for dynamic elastic-plastic analysis of rusted RC structures and reference for practical engineering applications.
