Análisis estadístico del periodo experimental de vibración en edificios aporticados de hormigón armado en el Distrito Metropolitano de Quito

Abstract

The aim of this research is to determinate an experimental equation that relates fundamental period with the most relevant parameter of buildings. (Height). This thesis contains a data base of 152 reinforced concrete framed building located in the Metropolitan District of Quito. Ambien vibration signals are recorded by an accelerometer at the top of the building for fifteen minutes. In order to obtain the fundamental period, the signals are processed with the Fourier Transform. The results were statistical analyzed. A comparative analysis of the experimental against codes is performed. It is also compared with experimental researches in other countries. This investigation calibrates a theoretician model where masonry is incorporated in order to obtain experimental results of ambient vibration.
