Abstract
Top -supported pre -stressed tie -arc aqueduct is a new type of aqueduct ,which possesses many advantages such as compact integer structure, no horizontal force on support piers, light pier and easy construction.Therefore, the new aqueduct has very high applicable values in engineering. Through on - site monitor and ANSYS modal analysis, detailed analysis on dynamic behavior of Jiehe top - supported pre - stressed tie - arc aqueduct is performed. The results show that the aqueduct is flexible structure because of long vibration period, transverse vibration is dominating , vertical rigidity is strong while out - plane rigidity of aqueduct is weak.关键词
