Análisis de la influencia de aisladores sísmicos en la respuesta modal de estructuras aporticadas de hormigón armado

Abstract

Due to the high seismic activity and the large economic and human losses of the last earthquake that occurred on April 16, 2016 in the city of Pedernales, the need to improve not only the rigor of the Ecuadorian Construction Standard in the chapters corresponding to Seismic Design and Reinforced Concrete, but also the implementation of seismic protection systems in both essential and special occupation buildings, not only for the prevention of collapse of the structure but also to preserve life and preserve the good state of Non-structural elements Initially, the use, importance, location, type of soil profile, the type of material by which the structure will be constituted and its dimensions will be determined. In the structural analysis it is necessary to model the guidelines and the characteristics to be considered in the commercial software for structure analysis, all this for a better corroboration with the data obtained through the manual calculation. The estimation of the loads to be applied in the structure and properties of the materials will be made according to the values imposed by the Ecuadorian Construction Standard for live load, dead load and specific weight of the materials, consequently the physical properties will be determined of the structure such as the mass matrix and the stiffness matrix, both necessary for the calculation of the period and the vibration modes.
