racron is the NOn-interactive Response CAlculator Reversed. It is a command line utility that calculates the dynamic response of systems with a single degree of freedom (SDOF), due to earthquake excitation or external force. It supports both linear and bilinear systems. The program reads a list of values describing the excitation from its input and calculates the relative displacement and relative velocity at each time step. The following numerical methods are available:
