Description

The response of single-degree-of-freedom systems to harmonic excitation has a very important part in structural dynamics. By understanding the response of the structures due to harmonic excitations, we can learn general information about the structure and its response due to different types of loads.

This paper consists of a brief theoretical part, and later focuses on the study of a linear response of a characteristic single-degree-of-freedom system, subjected to a set of external forced vibrations with various frequencies.

An algorithm for the computation of dynamic analysis (response history analysis) of SDOF system was developed in Excel VBA based on the numerical method of Interpolation of excitation.

In this paper, it is graphically presented the response spectra for a characteristic SDOF system, subjected to a set of external forced vibrations within varying frequencies. This graph helps to visualize the resonance effect of an external force over vibrating systems, which under specific conditions can be detrimental to the structural stability.
