    Análisis y diseño estructural del edificio Mushuc Runa de diez pisos en estructura metálica, mediante comparación del análisis estático lineal, modal, estático no lineal (Pushover), dinámico no-lineal (historia de respuesta), y diseño estructural en concordancia con el AISC 341-16, AISC 358-16, e incidencia en las condiciones actuales de la edificación

    The degree work in question consists of analyzing, through non-linear mathematical models, the seismic vulnerability of a building built in 2018 with structural steel (A572 GR 50) and a height of 9 floors with respect to the road. Likewise, the structural design carried out in 2017 (prior to construction), and compared with international standards, specifically those described in ANSI - AISC 341-16, 358s-16, 360-16, ASCE 41-13, FEMA 440, FEMA 273. The company AyF, Consultoría y Construcción provided all the necessary documents to carry out a correct seismic performance analysis; among the most important: mathematical model of analysis and structural design prepared in 2017, as-built plans prepared at the end of the work in 2018, ultrasound tests on welds, material quality certificates, architectural plans, among others. In this way and with all the documentation available, the expected results were obtained through nonlinear analysis (NSP) and (NDP), comparing maximum displacements, floor drifts, shear forces, formation of plastic hinges, failure, hysteresis diagrams and amount of energy dissipation; in this way, the level of seismic performance and the seismic vulnerabilityxviii of the structure were obtained for a design earthquake of 475 years of return period (earthquake considered due to the type of building) and it is expected that the civil works in question resist the design earthquake and is between the Operational – Functional states. Within the resilience rating with respect to FEMA P-58-1, the category that corresponds to the current system is "GOLD", where 10 percent damage and 4 weeks of occupation time are expected. Likewise, a comparison was made of the design carried out prior to construction (2017), with respect to the analysis carried out in this document; therefore, the dimensioning of cross sections used in the different structural members is justified. It should be noted that practical results have been obtained for the structural analysis specifically to the value related to the coefficient R (coefficient of seismic reduction) and that they can be extrapolated to different scenarios.
