- Abstract:
- Based on long-span and steel-concrete bridge,the perfect stochastic fluctuating wind field processis generated to simulate stochastic wind loads by using improved WAWS method. Then,the FEA model oflong-span cable-stayed bridge is established by using ANSYS.Based on ANSYS parametric design language,one calculation program is prepared to calculate the flutter and buffeting analysis for cable-stayed bridge withsteel-concrete composite girder.Some meaningful conclusions are drawn that flutter and buffeting would causevibration fatigue to reduce the lifetime of bridge members and endanger the safety of builders and machines.1nu,uei anu bueung asu uave wau euecus ou peuesu.al count anu ue seulny 0 mg-speeu 10au.Some meaningful references,which are used to calculate flutter and buffeting of long-span and steel-concretebridges,are provided for further research on wind-induced vibration for long-span bridges.
