Developed in this investigation are a method of analysis and a computer program for a sliding two-degree-of-freedom elastic system excited by ground motion. The system consists of two masses connected by a spring in parallel with a viscous damper. The motion of one of the masses, which slides on its support (or the ground), is damped in addition by a Coulomb (constant-force) damper representing sliding friction. Such a system has significant applications in the analysis of systems such as cranes, pipelines, bridges, and fluid-filled tanks. A study is made of the response of the system to a half-cycle velocity pulse, and the results of the study are summarized in the form of response spectra. Complete documentation of the FORTRAN computer program is included.
