Worldwide, unreinforced earthen buildings have shown poor performance during earthquakes, causing deaths and loss of property. The Spaniards that conquest the Americas built with earthen materials for about four centuries and therefore, there are a l

Applying the Covariance-driven Stochastic Subspace Identification method (SSI-COV) involves uncertainties in the numerical process of identifying modal parameters in a system. The main issue is that the method does not compute the uncertainty in the

Synchronization between production scheduling and real demand is an issue of great concern for production practitioners and academics. Put in a nutshell, the solution requires the placement of a decoupling point in order to get a trade-off between ef

Damage detection in beams by using artificial neural networks and dynamical parameters

Autor: Jesús D. Villalva, Ivan D. Gomez, José E. Laier

Publikováno v: Revista Facultad de Ingeniería Universidad de Antioquia, Iss 63 (2012)

In this paper is presented a multilayer perceptron neural network combined with the Nelder-Mead Simplex method to detect damage in multiple support beams. The input parameters are based on natural frequencies and modal flexibility. It was considered
