Abstract: Based on the generalized potential energy variational principle of nonlinear elasticity theory with large deflectionthe incomplete generalized potential energy functional is established on the space coupling free vibration of three-span self-anchored suspension bridge by considering the effect of coupling of flexural and axial actionand shearing strain energy of stifening girderBy constraint variationthe diferential equa tions of vertical vibrationlateral vibration and longitudinal vibration have been derivedWith the nonlinear items disregardedthe linear differential equations are establishedA self-anchored suspension bridge being constructed is taken as an example for the solution of frequency of linear vertical vibrationand the results are verified by comparing then with those obtained using the numerical methodsand theoretical basis is therefore provided for the analysis of free vibration of selfanchored suspension bridges
Keywords: self-anchored suspension bridge; coupling of flexural and axial action; free vibration
