En este trabajo se realiz? el an?lisis a un modelo a escala de una estructura porticada, donde los datos fueron obtenidos mediante un conjunto de sensores de aceleraci?n, aceler?metros, en donde sus medidas eran entregadas a un microprocesador, Arduino, en donde eran exportadas para su posterior an?lisis en una hoja de datos que se desarroll? para la completa comprensi?n de los datos obtenidos. En esta hoja de c?lculo, se realiz? un an?lisis por espectro de Fourier para obtener caracter?sticas importantes de la estructura, tales como: frecuencia de vibraci?n, periodo de oscilaci?n y modos de vibraci?n. Adicionalmente con esta caracterizaci?n elaborada de la estructura se realiz? un an?lisis modal de manera practica y de manera te?rica lo cual logro evidenciar que los resultados obtenidos mediante los ensayos experimentales son confiables.In this work the analysis was carried out to a scale model of a arcaded structure, where the data were obtained by means of a set of acceleration sensors, accelerometers, where their measurements were delivered to a microprocessor, Arduino, where they were Exported for further analysis in a data sheet that was developed for the complete understanding of the data obtained. In this spreadsheet, an analysis was performed by Fourier spectrum to obtain important characteristics of the structure, such as: vibration frequency, oscillation period and vibration modes. In addition to this elaborate characterization of the structure, a modal analysis was carried out in a practical way and theoretically, which showed that the results obtained through experimental tests are reliable.
