Determination and Comparison of Optimal Placement Scheme for Dalian Internatioanl Trade Mansion
This paper considers the problem of locating sensors on the flexible structures with the aim of maximizing the data information so that structural dynamic behavior could be fully characterized. Since only translational degrees of freedoms (DOFs) are considered for possible sensor installation in the state-of-the-practice, a method which could avoid distinguishing the translational and rotational DOFs is presented. In order to realize the proposed method and to demonstrate its effectiveness, three different sensor placement techniques, EfI, EfI-DPR and Uniform, were employed to a super tall building. The calculation results showed that the proposed method is easy in understanding and could be used practically by civil engineers. EfI method provides a more effective method for optimal sensor placement than other ones to identify the vibration characteristics of the studied building.
