The objective of this paper was to establish the degree of correlation between the results obtained from a 3/8 scale plastic model, an actual frame, and a mathematical computer model. Results showed that a satisfactory dynamic simulation can be obtained from a scaled plastic model of the structure and that a mathematical model composed of beam elements is accurate at the lower frequencies but begins to differ with the actual frame at higher frequencies.
