To investigate the spatial performance of concrete filled steel tubular arch with corrugated steel webs, a static loading test has been conducted on an arch with a clear span of 6m subjected to in-plane and out-of-plane loading simultaneously. The structural behaviors such as load-displacement relation, ductility, distribution of strains in tubes and corrugated webs, were explored. Based on the results, it is demonstrated that the lateral deformation is the critical factor for the ultimate load-carrying capacity of the arch. In the whole process of test for the tubular arch, material non-linearity is dominant and geometrical non-linearity is subordinate. It could be concluded that the CFST-CSW arch shows good structural behavior and may be applicable in practice. 漏 (2012) Trans Tech Publications.
