Abstract: Based on a concrete-filled steel tube rigid frame tied arch bridge, the finite element model of the bridge is built with large general structure finite element program ANSYS. Each construction stage will be considered as the real engineering too, so to determine the design tensile force of the tie-bar in all stages. Though comparing the inner force of the arch rib with different arch axis coefficient, the reasonable arch axis shape will be identified finally. At last, stress superposition theory is used to check the stress in the arch rib; the related research results and conclusion can supply experience and practical reference to another homologous tied arch bridge.
