Abstract: In this study, the suitability of current design methods for the 0.2% proof yield strength of the corner regions for high strength cold-formed steel at normal room temperature was investigated. The current standard predictions are generally accurate for outer corner specimen but conservative for inner corner specimen. Based on the experimental results, an analytical model to predict the corner strength of high strength cold-formed steel at normal room temperature was also proposed. The comparison indicated that the proposed model predicted well the corner strength of high strength cold-formed steel not only at normal room temperature but also at elevated temperatures. It is shown that the predictions obtained from the proposed model agree well with the test results. Generally the corner strength enhancement of high strength cold-formed steel decreases when the temperature increases.
