Abstract
A method for probabilistic assessment of seismic resistance of long-span arch bridge based on time-frequency hybrid computation includes: S, parameter acquisition; S, modeling; S, model preprocessing; S, piecewise interpolation of a time-frequency modulation function; S, response expression derivation; and S, probabilistic assessment of seismic resistance. By integrating spectral decomposition technology, a modal superposition method, and piecewise interpolation technology for time-frequency modulation functions, an explicit response expression of a long-span arch bridge structure is derived under conditions of arbitrary time-frequency modulated seismic excitation, which greatly saves the computational cost of probabilistic analysis of the non-stationary seismic response of the large arch bridge structure, and achieves efficient probabilistic assessment of the seismic resistance of the arch bridge structure.
