Model updating of multistory shear buildings for simultaneous identification of mass, stiffness and damping matrices using two different soft-computing methods

► Two novel methods for identification of mass-damping-stiffness of shear buildings. ► In the first method, modal properties are estimated from forced vibration responses. ► In the second method, a direct strategy of structural identification is developed. ► The noise effects may partially be eliminated by using high-order FIR filters.
