Failure modes and loading bearing capacity of corrugated steel roofs connected by standing seam clips
Abstract This paper presents the research on failure modes and loading bearing capacity of two types of purlin-sheet roofs under uniform loadings. The full-size experiments are carried out on the purlin-sheet roofs and the allowable design stress and design proposals are proposed. Besides, the finite element analysis is conducted to compare with the experiments. Results show that the failure modes and loading bearing capacity of two types of purlin-sheet roofs are different. The first is that the adjustments are pulled out from the base, while the mechanical occlusions between the adjacent sheet and adjustments are well. The latter is that the mechanical occlusions between the adjustment and sheets are tensioned fracture, while the adjustment are tensioned straight and pulled out from the sheets. The numerical calculations and experiment data are in good agreement, and the deviations are mainly because of initial defects of specimens, construction errors of specimens and loading protocols. The numerical calculation method is reliable and can be used to analyze the sheet-purlin roof connected by standing seam clips.
