Article Preview

Parametric analysis of ultimate loading capacity is performed by the finite element method considering the dual non-linear effects for inner concave cable-arch structure with different arch rise-span ratio. The results show that for the inner concave cable-arch structure with other given conditions, the failure loads of the steel arch and the cable increase with the increase arch rise-span ratio, but the increasing ratios are different. The failure modes of inner concave cable-arch structure may be divided into three types: the steel arch failure, the overall failure and the cable failure. According to the considered parameters range in this paper, the steel arch failure mode may occur when the arch rise-span ratio is less than 0.3; the overall failure mode may occur when the arch rise-span ratio is between 0.3 to 0.35; and the cable failure mode may occur when the arch rise-span ratio is greater than 0.35. This provides some useful references for rational design of such structures.
