“…For the deck-type systems having arch ribs with certain, flexural and contractive stiffnesses, fixing the end-supports of the arch ribs is, speaking from view point of their ultimate strengths, more effective than making flexural stiffness of the deck girders in the two-hinged system higher. (8) The possibility of the local member failure becomes high as the number of panel decreases and the load intensity ratio, r, is merged to unity. In addition, the local member failure is apt to arise as the flexural stiffness of the arch rib becomes smaller than that of the deck girder and the slenderness ratio of the bridge system decreases.…”

Fixed-end restraint effect of arch ribs on the over-all, in-plane ultimate strength of deck type steel arch bridges is studied by an accurate nonlinear finite element approach. This approach takes into consideration the two important factors on nonlinearities, namely, geometric and material.The interaction between bending moment and axial thrust, the changes in deflection mode, and the progress of yielding and unloading zones with load level until the ultimate state are throughly examined.The load-deflection behavior, until the stability limit load is reached, has also been analyzed by elastic theory. Special characteristics of the local member failure of arch rib between the posts are finally investigated.

“…The effect of lateral horizontal force on the in-plane strength of arch bridges was studied by Kuranishi (1961b), Yabuki and Kuranishi (1973), and Kuranishi and Yabuki (1977). They determined that the in-plane strength of arch bridges with a close brace over the entire length of the arch is not significantly affected by lateral loads typically encountered in actual structures.…”

The method with the separation of rigid body displacements is a powerful tool for the finite displacement analysis of structures particularly with curved members, with variable cross sections, and/or with inelastic behaviors. Nevertheless, its theoretical equivalence to the solutions of the direct Lagrangian equations has not been examined so far. This paper presents the theoretical convergence and accuracy of the method, where an original curved element of variable cress section is considered as well as an approximate straight element of constant cross section.
