The Transfer Matrix Method for Seismic Analysis of Curved Box Bridges under Multi-Support Excitation in Frequency Domain
In this paper the transfer matrixes out plane of curved bridge are derivated.based on the FFT transform and the relationship between the quality and inertial force the point transfer matrix for vibration analysis is biult, and then establish the vibration transfer matrix and the total transfer matrix. Derivates the frequency domain transfer matrixes of single-span curved box bridges under uni-support or multi-support excitation, and offers a new method for seismic analysis of curved box bridges under multi-support excitation in frequency domain.
