Análisis estructural del desempeño sísmico del edificio de la Facultad de Ciencias Agropecuarias bloque 1 mediante la medición de vibraciones

Abstract

In the present research work, a qualitative and quantitative analysis was carried out to determine the seismic vulnerability of the building of the Faculty of Agricultural Sciences Block 1 of the Technical University of Ambato. The qualitative analysis was carried out through a quick visual inspection with the forms proposed by the FEMA 154 and NEC 15 methodologies, where it was determined that the structure has a high degree of seismic vulnerability caused by irregularity in: plant and elevation, year of construction, the type of soil and hitting problems with adjacent structures. The quantitative analysis was done using the ETABS software for which we found out the behavior of the structure with a modal spectral analysis in which it was determined that it does not comply with the NEC 15 standard because it has large floor drifts and its vibration period is not among the ranges established by standard. With these results of the two methodologies used, a proposal for the reinforcement of the building was made, which at a global level is the placement of cutting walls that provide greater rigidity and at the local level of the elements with a steel jacketing in both beams and columns, then the quantitative analysis was carried out again where it was possible to comply with the requirements established by the Ecuadorian Construction Standard.
