Verificación del comportamiento dinámico a torsión de un modelo físico tridimensional con base en ensayos en mesa vibratoria

Abstract

At present, the theorical and practical study of Structural Dynamics is very important by means of simulation or laboratory tests. The main objective of this work is that Civil Engineering students can observe the dynamic behavior with torsion in a three-dimensional model. The test is carried out using a shaking table owned by the Salesian Polytechnic University and the resolution of the analytical model based on the application of the Newmark Method to obtain the response of the dynamic system. A 2-level model was built, it is made up of stainless-steel columns and acrylic plates, in addition it is composed of steel ingots (masses) which can be placed at different points of the structure to verify the dynamic behavior to torsion. The results obtained in the tests are consistent, this allows validating the applied methodology and assuring the performance of the equipment used.
