ABSTRACT     This article presents two methodologies for the identification of stiffness and flexibility matrices of framed building under shear behavior. Both methods require an initial (theoretical) value of the characteristic matrices, to be adjusted. They also require an experimental (real) modal frequency and its eigenvector.     The mathematical formulae are presented. A four-story framed building is analyzed. Its initial stiffness are changed in order to represent seismic damage. Obtained results are exact, showing precision of both methodologies.
