Análisis estructural de la edificación del hospital del IESS Cantón Zaruma bloque b1

Abstract

In the present work, the structural analysis of the "IESS Hospital" of Zaruma canton is carried out based on a resistant earthquake design philosophy as established in NEC_SE_DS section 4.2, which allows to demonstrate the level of safety, the design earthquake was performed for a return period of 475 years. The elastic spectrum of design depends on the type of soil, seismic zone, the region where the construction will take place for the value of n, the value of r depends on the type of soil and other values Fa, Fd, Fs are taken as specified the NEC_SD_DS section 3.2.2, for the calculation of To and Tc which are the limiting periods of vibration. We calculate the basal shear, in which we use a seismic reduction factor that according to the NEC corresponds to the structural typology, but that we must also take into account according to the type of sections and their ductility. The AISC 360-10 standard was used to check the structural elements such as beams and columns depending on the type of section. In the ETABS software we carry out the modeling of the structure, we enter values of live load, dead load on loads, seismic load and load combinations obtained from the NEC_SE_CG section 3.4.3; we obtain the maximum floor drift that must not exceed the inelastic drift limit of 2% according to section 4.2.2 of the NEC_SE_DS, in the same way we obtain the values of the basal shear and so we proceed to perform the respective correction.
