Análisis estructural del desempeño sísmico del edificio de administración de empresas, bloque 1, de la Facultad de Ciencias Administrativas mediante la medición de vibraciones

Abstract

In this research, a qualitative and quantitative analysis was carried out to determine the vulnerability of the Business Administration building, block 1 of the Technical University of Ambato. In the qualitative analysis, a quick visual inspection was carried out, and through the matrices provided by FEMA 154 and NEC 2015, the seismic vulnerability was determined where the structure was classified as potentially dangerous to seismic activity, this classification was obtained by irregularities in plan and elevation, soil type and knocking problems with adjacent structures. In the quantitative analysis, with the Etabs software, a dynamic spectral analysis was carried out to know the structural behavior, where it was shown that they do not comply with the NEC 2015 Standard, later a non-linear static analysis was carried out with the ATC-40 methodologies and FEMA-440 where it was found that the structure does not have enough capacity to reach the expected performance level according to the NEC 2015, the analysis of vibrations due to human activity was incorporated when making use of the building, the structure was modeled according to the AISC 11 standard and it was verified that it does not present vibration problems. A structural reinforcement proposal was made to incorporate rigidity using San Andrés crosses and, to provide ductility, the structural elements were reinforced with steel cladding, then the quantitative analysis was carried out again where it was possible to comply with the requirements established by the standards.
