Parametric Analysis of the Ultimate Load-carrying Capacity of the Concrete Filled Steel (Single) Tubular Arch under In-Plane Loads

Baochun Chen

Abstract

With the dual non-linearity finite element program, the nonlinear behaviors and ultimate load-carrying capacitys of the Concrete Filled Steel (single)Tubular (CFST) rib arches are analyzed for the whole stressing process. The analyzed parameters include the rise to span ratios, slenderness ratios, steel ratios and loading conditions. The results can be referred to in putting forward an practical algorithm for the ultimate load-carrying capacity of the CFST arches, and can be useful for practical engineering.
