This thesis investigates the acceleration amplification experienced by solar towers mounted on the rooftops of low-rise industrial buildings during a seismic event. Specifically, this thesis looks to assess the validity of using amplification factors adopted by the ASCE 7-05Minimum Design Loads for Buildings and Other Structures to approximate seismic acceleration amplification for roof-mounted solar towers. To investigate the validity of the ASCE 7-05 amplification factors, this thesis conducts timehistory analyses of three theoretical solar towers mounted on the roof of a case study building. The time history analyses are conducted in the finite element computer modeling program SAP 2000 using 30 historical ground motion records of varying frequency content. Based on the results of the time history analyses, modifications to the ASCE 7-05 provision specific to roof-mounted solar towers are proposed.

Actualmente la población limeña no cuenta con viviendas propias y seguras; por ello, surge el auge del rubro de la construcción masiva con grandes edificaciones multifamiliares, cuya resistencia al impacto telúrico de enorme magnitud de 8 a 9 grados sigue en prueba sísmica; por ende, es muy relevante realizar la comparación del análisis del método modal espectral de la estructura (desplazamientos y aceleraciones respecto al suelo) y un análisis del método tiempo-historia donde se obtendrán las deformaciones máximas de la estructura de los edificios en este presente estudio; asimismo, evaluará la vulnerabilidad de la construcción estructural mediante acelerogramas sintéticos utilizando como espectro objetivo el espectro de peligro uniforme obtenido en el Parque de la Reserva, Cercado de Lima, por medio de un estudio peligro sísmico para un periodo de retorno de 475 años, reconociendo el comportamiento estructural ante un sismo de gran magnitud. El presente estudio titulado: Análisis de la amplificación sísmica de edificios del Cercado de Lima – Lima y La Punta – Callao por medio del análisis modal espectral y tiempo – historia mediante acelerogramas sintéticos; cuyo objetivo es realizar la comparación de dichos métodos en 4 edificios (2 de 5 niveles y 2 de 12 niveles) cuya configuración estructural es de muros de concreto armado, los cuales se estudiaran en dos distintos tipos de suelo (Cercado de Lima y La Punta) con la finalidad de obtener resultados de derivas, fuerzas, desplazamientos y aceleraciones para determinar la amplificación sísmica en los suelos mencionados, y así optar por el método de análisis más óptimo. Asimismo, el propósito del presente estudio es conocer el comportamiento de la edificación acorde con la realidad peruana; es decir edificaciones con periodos cortos; el cual evaluará la vulnerabilidad mediante acelerogramas sintéticos, reconociendo el comportamiento estructural ante una eventualidad sísmica de gran magnitud. / Currently, the population of Lima does not have their own and secure homes; For this reason, the boom in the field of massive construction emerges with large multi-family buildings, whose resistance to the telluric impact of enormous magnitude of 8 to 9 degrees continues in seismic testing; therefore, it is very relevant to make the comparison of the analysis of the spectral modal method of the structure (displacements and accelerations with respect to the ground) and an analysis of the time-history method where the maximum deformations of the structure of the buildings will be obtained in this present study. ; Likewise, it will assess the vulnerability of structural construction using synthetic accelerograms using the uniform hazard spectrum obtained in Parque de la Reserva, Cercado de Lima as the objective spectrum, through a seismic hazard study for a return period of 475 years, recognizing structural behavior in the face of a large earthquake. The present study entitled: Analysis of the seismic amplification of buildings in Cercado de Lima - Lima and La Punta - Callao by means of spectral modal analysis and time - history using synthetic accelerograms; the objective of which is to compare these methods in 4 buildings (2 of 5 levels and 2 of 12 levels) whose structural configuration is made of reinforced concrete walls, which will be studied in two different types of soil (Cercado de Lima and La Punta ) in order to obtain results of drifts, forces, displacements and accelerations to determine the seismic amplification in the mentioned soils, and thus opt for the most optimal analysis method. Likewise, the purpose of this study is to know the behavior of the building in accordance with the Peruvian reality; that is to say buildings with short periods; which will assess vulnerability using synthetic accelerograms, recognizing the structural behavior in the event of a large seismic event. / Tesis
