Resumen

According to the Geophysical Institute of Peru, the city of Huancayo presents high values of acceleration and dynamic intensity, classified as a zone of great seismic danger. This work develops the Stewart platform as a seismic isolator for water storage tanks through active control in the city of Huancayo. For the dynamic analysis of the structure we took into account the properties of the fluid, impulsive mass, convective mass, modeled and analyzed by SAP2000 to analyze the structural behavior, Revit 2021, SolidWorks and also used the Arduino Mega and a gyroscope to obtain the acting vibrations in the 3 different directions and to process them to move the pistons in the opposite direction to the movement. Finally it was obtained that the Stewart platform helps to reduce vibrations in the structure by the 6 degrees of freedom it has, in the analysis of the tank walls it was observed that the moments were reduced by 62.47% and the lateral displacements were reduced achieving stabilization of the structure through active control.
