| Abstract: | The dynamic characteristics of hangar of Capital Airport were tested by means of pulsatile theory for further study. The data were analyzed by using of spectrum analysis method. Frequency and mode of structure are gained. Based on the engineering structure, three dimensional finite element model is set up by SAP2000N software and its characteristics is calculated by eigenvectors method. The difference between test results and calculated results are less than 8 percent and the modes are similar. |
