Abstract

The purpose of this study is to present a method of updating the model-based stiffness matrix using the measured data in static system and expanding to the displacements at all degrees of freedom. Using the measured data set as a constraint, the mathematical form of the updated stiffness matrix is derived using the least squares method to minimize the difference between the analytical and actual stiffness matrices. The expanded displacement responses include the rotation responses. The validity of the proposed method is illustrated in two numerical examples to update the stiffness matrix and expand the displacements of a cantilevered beam and a truss structure.
