| Abstract: | During the detection and technical state evaluation of the bridge structure,some problems appear when structural dynamics theory is applied.Several problems of structural dynamics application are analyzed and discussed,such as the relationship beween the displacement response and the strain energy for each mode,structural free decay response and its application for identifying the damping factor of bridge structure,the relation ship between the damped natural frequency and the undamped natural frequency of ... |
| Keywords: | dynamic characteristics of structure natural frequency loading test of bridge modal analysis |
