Compressive tests of cold-formed steel curved panels

Abstract This paper discusses the compressive tests of cold-formed corrugated steel curved panels. In the absence of either a standard test protocol or a reported test on compressive tests of curved panels, this paper presents two types of compressive tests; namely, the corner and flange-section test, and full-section test, for curved specimens with primary focus on the experimental set-ups and test procedures. A total of 198 compressive tests, which consist of 114 corner and flange-section tests and 84 full-section tests, were conducted to investigate the influences of panel curvatures and transverse corrugations on buckling behaviour of cold-formed corrugated steel curved panels. The proposed test approaches yield consistent results; therefore, they could be considered reliable for compressive tests of curved specimens.
