This thesis proposes a new algorithm for selecting optimal displacement measurement location to estimate structure deformed shape. A reasonable guideline is presented to select optimal displacement measuring locations and the number of sensors by using this algorithm. Algorithm is divided into two parts. First, to select location of displacement measurement, EI-SF (Effective Independence- Shape Function)Method is proposed by structural shape functions. Second, to select optimal displacement measurement location, ODL (Optimal Displacement Location)Method which is consisting of positioning and structure shape estimation is proposed by grafting EI-SF Method and structural deformed shape estimation SFSM-LS (Structural Shape Function Superposition Method-Least Squares)Method (Choi, Jun Ho, 2011)
In order to verify the proposed algorithm, a numerical problem on a two-span beam was carried out. Based on the FE Model, influences of the number of measuring locations and structural shape functions are investigated on the accuracy of the estimation for selecting optimal location. Through the study of numerical example, it could be observed that the proposed algorithm is effective method.
