La presente investigación propone un procedimiento general de análisis para edificios altos sobre la base de los requerimientos de la Norma Peruana E.030.
Primero, se realiza la configuración estructural de los edificios, se define el número de edificios y la cantidad de niveles, así como el sistema estructural predominante. Luego, se definen las características de los materiales, las cargas y las combinaciones.
Los casos de estudio que se desarrollan se basan en edificaciones altas peruanas existentes como el Hotel Westin Libertador y el Banco de la Nación. Para la configuración estructural se utilizó el sistema estructural de núcleo rígido debido a su gran versatilidad y funcionalidad.
Después, se describen los métodos de análisis de estructuras altas y se procede con el análisis de la verificación de derivas y realizar una comparación de la cortante en la base mediante el análisis estático, análisis dinámico modal espectral y análisis lineal tiempo historia. Para el análisis tiempo historia se empleó 5 registros peruanos espectro compatible, mientras que para el diseño de las placas de concreto armado se usó el análisis modal espectral. / Abstract. Currently, there is an increase in the demand for tall buildings in the city of Lima. This research proposes to reduce the dynamic amplification factor through the seismic design of tall buildings based on the requirements of Peruvian code considering that they are regular in plan and height. Mini-mum base shear values according to the comparison of static seismic shear and dynamic shear from spectral modal analysis were reviewed for cases of buildings larger than 120 meters. The study of 28 reinforced concrete build-ings was proposed, with different heights - varying from 24 to 36 floors, with different floor configurations, as well as the arrangement of the walls considering as a rigid core structural system. Additionally, the characteristics of the materials, the loads and combinations were defined. The responses of these buildings were determined by the response spectrum analysis (RSA) and then compared with those obtained by the lineal response history analy-sis (LRHA), for the last analysis, five Peruvian seismic records were used and scaled to 0.45g. The seismic responses of the LRHA procedure were taken as benchmark. The result of this study is the analysis and proposal of the C / R factor for high-rise buildings, as well as obtaining the base shear and drift verification. Minimum base shear values can be reduced for high or long-term buildings, being regular in plan and height. / Trabajo de investigación
