Abstract:
In order to describe the mechanical behavior of selfanchored suspension and cablestayed combination bridge under service stage, the full bridge model with scale ratio 1∶20 is built based on the similarity theory. Through the model test, the deformations of main cables and main girders are analyzed. The mechanical characteristics of the tower are also studied. The results show that: the maximum increase of tower stress is 2.08 MPa in service stage; the change of force in cablestaged bridge has great effects on the deformation of selfanchored suspension; compared with the case of symmetrically loading on main span, the deflection of main span decreased by 14.3% in the case of symmetrically loading on the full bridge. 3 tabs, 9 figs, 6 refs.
