This chapter extends the substructuring methods to the fast and precise computation of structural responses and response sensitivities. The vibration equation of the global structure is expressed by a small number of master eigenvectors, while the elastic effects of slave modes are compensated by the residual flexibility. The response sensitivities are computed from the the derivative of one substructure containing the designed parameters solely. This not only ensures high precision of structural responses and response sensitivity, but also improves the computational efficiency by reducing the size of the vibration equation.
