Obtención de modelos de cálculo de sistemas provisionales de protección de borde mediante la técnica de análisis modal operacional

Abstract

In this work were obtained by Operational Modal Analysis (OMA) vibration modes and frequencies associated with temporary of protection systems (TEPS) built with planks of pine wood and steel poles. These systems have been evaluated analytically, using a finite element model (FEM). For the FEM we obtained the elastic constants of wood using ultrasound. The results of experimental and analytical assessment in the first vibration modes match in reasonable ways.
