In the preceding chapter we studied the response of a single degree-of-freedom system with harmonic loading. Though this type of loading is important, real structures are often subjected to loads which are not harmonic. In the present chapter we shall study the response of the single degree-of-freedom system to a general type of force. We shall see that the response can be obtained in terms of an integral which for some simple load functions can be evaluated analytically. For the general case, however, it will be necessary to resort to a numerical integration procedure.
