Abstract
Influences of cavity on in-plane stability behavior of parabolic CFST arch ribs are analyzed with ANSYS. Considering different cavity ratio, steel ratio and rise-to-span ratio, material and geometric nonlinearities analysis of parabolic CFST arch-ribs under different in-plane load cases are conducted. It is concluded that the bigger the cavity ratio is, the lower stiffness and bearing capacity of arch-ribs will be. With the same cavity ratio, including section cavity ratio and rib cavity ratio, there is more significant influence with the smaller steel ratio and the more uniform distribution of vertical loads. Moreover, there is little influence of common rise-to-span ratio on stability reduction due to the existence of cavity.
