Virtual bat algorithm for the computation of Duhamel’s Integral applied to structural systems with one degree of freedom

Sergio Vanegas, Iván Amaya, Rodrigo Correa

Abstract


The current article presents the use of the virtual bat optimization algorithm, for solving Duhamel’s Integral in dynamic systems with one degree of freedom. Some situations are solved, as a demonstrative example, calculating global maxima. The results found were comparable (both, in precision and in accuracy) to those achieved with other calculation approaches. In a similar fashion, acceloremeter data of a Chilean seism (2010) was used to calculate the dynamic response and its maximum displacement. In all cases, the number of virtual bats were varied, noting an influence over the run time.
