풍응답 계측을 통한 주거복합 건물의 동적특성 평가

The dynamic properties of structures are generally required for the design of large scale structures subjcet to wind loads. The wind tunnel test studies, therefore, are generally used for the evaluation of the wind effects on the structures. The accuracy of the wind tunnel test is obviously important to acquire reliable results of wind effects. The reliability of the dynamic properties of the structures, however, are also pivotal to evaluate the wind effects close to actual ones. The dynamic properties are generally evaluated by the modal analysis of the FE model. It has been reported that those are considerably different with actual dynamic properties in some cases because actual structures couldn't be fully represented by the FE model. In this study, the dynamic properties of residential tall buildings were investigated through measurement of wind-induced responses.
