Simulation of Wind Loading for Large - span Bridge Structures[J]. Journal of Civil and Environmental Engineering, 2005, 27(3): 63-67. DOI: 10.11835/j.issn.1674-4764.2005.03.024.
Wind speed time series obtained with numerical simulation methods are adopted in structural analysis of wind - induced vibration. In this paper
based on the natural wind properties and the correlativity of nodal wind speed time series
AR model is employed to simulate wind speed time series
and the AIC rule is used to fix the rank of the AR model. Statistical analysis results of numerical wind speed time series show that AR model is efficient in simulating nodal wind speed time series which has time and space correlativity
and that the simulation precision
simulation efficiency and calculation stability answer the needs of practical engineering.
