    Análisis estructural del desempeño sísmico del edificio de la Facultad de Contabilidad y Auditoría de la Universidad Técnica de Ambato mediante la medición de vibraciones

    To determine the seismic performance of the structure in its current state, a vulnerability analysis was performed by applying a qualitative and quantitative method. In the vulnerability analysis of the qualitative method, the rapid visual inspection technique described by FEMA 154 and NEC 2015 was used, taking into account the most relevant characteristics of the structure, the type of structural system, irregularities in plan and elevation, year and construction code, presenting a high vulnerability degree according to Fema 154 and a low vulnerability degree according to NEC 2015. In the quantitative analysis, a linear analysis was performed to know the structural behavior, where it was shown that they do not comply with the NEC 2015 standard, subsequently a non-linear static analysis was performed with the ATC-40 and FEMA-440 methodologies and where it was proven that the structure does not have enough capacity to reach the expected performance level according to the NEC 2015. With the results of the two methodologies, it was proposed the reinforcement at a global level with shear walls and at a local level with steel jacketing for beams and columns in order to ensure compliance with the performance levels. Finally, a comparison was made between the vibration periods obtained by the NEC-SE-DS methods and the period obtained by the empirical formulas based on environmental vibration studies, in order to relate the degree of vulnerability of the structure with the vibration periods.
