This study presents a test program on the behaviour of cold-formed tubular section subjected to interior localised loading at elevated temperatures. Six cold-formed austenitic stainless steel rectangular hollow section specimens were tested. The localised loading tests were carried out as per Interior-One-Flange (IOF) loading condition outlined in the American Specification for designing cold-formed stainless steel structural members, by adopting steady state test method at various temperatures up to 800 ℃. The obtained test data, including the measured geometric dimensions, temperature histories, failure modes, load-deformation curves, and web crippling strengths of the specimens at varying temperatures, were presented. The impact of elevated temperature on the web crippling strengths of cold-formed austenitic stainless steel tubular section under the IOF loading condition was revealed. The suitability of the current web crippling design provision codified in the updated American Specification to elevated temperature conditions was evaluated. The comparison results indicated that the codified design guideline offer conservative estimations of the web crippling strength for the tested cold-formed austenitic stainless steel tubular section at elevated temperatures.
