Análisis estructural del desempeño sísmico de los laboratorios de hidráulica, hormigón y mecánica de la Facultad de Ingeniería Civil y Mecánica de la Universidad Técnica de Ambato mediante la medición de aceleraciones

Abstract

The procedures used in the analysis of the structures are qualitative and quantitative through formats and matrices of FEMA 154 and NEC 2015, with the purpose of recognizing and classifying the structure for its seismic vulnerability. With the two proposals that were used in the project, it was determined that the degree of vulnerability of the structures is high, since the punishment factor for buildings is small, for the analysis the most relevant parameters were: irregularities in plan and elevation, the structural system and the type of soil. With all the information collected, the linear static analysis and the nonlinear static analysis were carried out to verify the modal factors and the behaviour of the structures. With the results obtained from the linear analysis, it was concluded that the vibration period and the floor drifts in two of the structures comply with the provisions of the NEC 2015, unlike the Concrete Laboratory that presented many problems in its design and analysis, each The structure presented a torsional behaviour in its vibration modes and with respect to the nonlinear static analysis, two of the buildings were executed that comply with the capacity for the different levels of seismic threats, with respect to the Concrete Laboratory that has a high degree of seismic threat. With the results of the two methodologies used, a reform proposal was made for the building of the Concrete Laboratory. Finally, a comparison was made of the periods obtained by empirical formulas that were based on environmental vibrations, to relate them to the degree of vulnerability of the structures.
