Analysis On The Dynamic Behavior Of Cable Tower Of Harbin Sifangtai Cable-Stayed Bridge

The dissertation mainly is involved in simulated calculation on the modeling of Harbin Sifangtai Cable-Stayed Bridge with finite-element method software Sap2000, in simulated calculation on the Static load study under the phenomenons in which Sifangtai Cable-Stayed Bridge is in the state without earthquake, and in the ability of loading proofSafety test. Abovely the proofsafety under the static and dynamic load is enough obviously.Additionally this dissertation mainly is involved in simulated calculation on the dynamic behavior of a cable-stayed bridge with modeling of a cable-stayed bridge for dynamic analysis and response spectrum method. According to the analysis on proofSafety of earthquake at the area of Harbin Sifangtai Cable-Stayed Bridge and the simulated calculation on the dynamic behavior, it is reasonable to conclude that the pier is safe under the grate shear load.Conclusionly though Haerbin Sifangtai Cable-Stayed Bridge is a kind of large-spaned bridge, the rationality of the design about structures and cross-sections is enough to proof that the proofsafety under the earthquake.
