Introduction In civil and mechanical engineering, the modal identification approached for dynamical system the numerical model has been assumed beforehand such as linear system, time-varying system and nonlinear system.
However, the nonlinear dynamic behaviors of many practical examples have been reported in the engineering literature.
Methodology The structural system encountered in civil and mechanical engineering can be described by the following equations of motion, , (1) where M, C and K are mass, damping and stiffness matrices, respectively, and C and K are functions of amplitude of responses, while x and f are displacement and force vectors, respectively.
