A Parameter Ascertainment Method for the Skeleton Curve of Corroded Reinforcement Concrete Members with Flexure and Compression

This paper presents an effective method of parameter ascertainment for the skeleton curve of corroded compression-bending members to establish its restoring force model. An assumption which considers the skeleton curve of damaged and undamaged members has similar shape is introduced into the fitting...
