Timoshenko Analytic solution of Timoshenko beam excited by real seismic support motions

摘要

The present invention relates to a dynamic analysis method of Timoshenko beams by a supporting point movement and a real earthquake, which comprises: an equation of motions input step in which an equation of motions of beams is input; an information input step in which basic information for dynamic analysis for movements of the beams is input; and a numerical analysis step which, based on the equation of motions and the basic information, uses a quasi-static decomposition method and an eigenfunction expansion method to derive motion information of the beams. According to the present invention, the dynamic analysis method of Timoshenko beams by a supporting point movement and a real earthquake can efficiently analyze motions of Timoshenko beams, which can represent slender beams and stocky beams together, by supporting point movement and a real earthquake, and can conveniently and precisely analyze motions of beams.
