Paper Title:
Debonding Effects on Internal Force and Stiffness of Single Tube Concrete-Filled Steel Tubular Arch Rib
  Abstract

In this paper the relationship of total internal force between complete debonding situation and complete bonding situation, the calculation formulas of moment distribution between steel tube and filled concrete on the complete debonding condition are deduced from the complete debonding calculation model of CFST arch rib and corresponding differential equations of geometry and internal force. Based on principle of virtual work, the relationships of radial displacement between complete debonding situation and complete bonding situation are deduced, and the results were verified by finite element method. The research results for constant section single tube CFST arch rib indicate that the total internal force of any section on the situation of complete debonding is equal to that on the situation of complete bonding if the axial strain is ignored; the moments of steel tube and filled concrete are distributed according to the ratio of their bending stiffness; the stiffness of CFST rib does not decrease with pure debonding.
