Abstract:
The static stress, stability and natural vibrating frequency of concretefilledsteeltube arch bridge with different arch rib leaning angles under constant load are calculated by finite element program. The relations of structural displacement, internal force, stable coefficient and natural vibrating frequency with leaning angles of arch rib are analyzed. The results show that: when the leaning angle of arch rib is increased, the structures lateral stability and lateral stiffness can be increased effectively, and member moments in the middle span and horizontal force in the arch skew can be decreased greatly, and they will reach the minimum values when the leaning angele is 8°; but when the leaning angle is below 3° or over 8°, to increase the leaning angle has little influence for increasing lateral stiffness; the changing of leaning angle also has little influence on arch stability, torsion rigidity and the vertical displacement of structure. The above analysis means that 8° is an appropriate value to arch rib from the views of static and dynamic mechanics. 3 tabs, 8 figs, 8 refs.
