| Abstract: | The technology of autogressive-type simulation method is introduced to simulate turbulent wind loading with time and spatial correlation. Then the paper gives autogressive-type simulation process and MATLAB program. Turbulent wind velocity of Gushan bridge over Minjiang river is generated with this program and the result indicates that the program is good, which can meet engineering requirements. |
