【Abstract】 Based on the study of references [1] and [2], this paper is concerned with the dynamic characteristics of Prestressed Plane Cable-Arch mixed system. The simplified calculating formulas of natural frequencies of the system are derived on the basis of continuum theory. Theoretical results are well verified by experimental measurements of reference [1].更多还原
