- Abstract
To calculate the vertical frequency of self-anchored suspension bridge conveniently,the selfanchored suspension bridge with double-tower was taken as research object. Frequency formulas for first symmetric and asymmetric vertical vibration modes were induced by Rayleigh method,and the influence coefficient for tower stiffness was proposed. The presented theoretical formulas were validated by engineering project,and the application condition was discussed. The results indicate that tower stiffness has great influence on first symmetric vertical frequency, which should be correctly considered in frequency calculation. The error between values calculated by the proposed formula and the finite element method can meet the requirement of conceptual design. The proposed formulas can be applied into the self-anchored suspension bridge with double-tower.
