Currently in Lima city there is a limited number of high-rise buildings. So, there isn’t much literature on this type of building in Peru. Peruvian codes focus on medium and low-rise buildings. Therefore, more detailed studies are required to analyze and design these tall buildings more appropriately according to the reality of the country. In this thesis, the modal pushover analysis of 6 types of 35-story reinforced concrete buildings in Lima city will be developed. Three building models with different structural system and with different plan (square and rectangular) are proposed, being their areas of 29m x 29m and 52m x 26m respectively. These structural systems are rigid core and frames with an energy dissipation system (viscous fluid dampers and SLB dissipators) in order to study their behavior against seismic stresses. These buildings were established based on the criteria and requirements of the current codes in the country, as well as, the distribution of the floors of buildings commonly used for offices and homes. Natural periods were found to range from 2.6 to 3.3 seconds for rigid core buildings, there is an increase for viscous damping buildings from 4.2 to 5.4 seconds and also for SLB devices to range from 3.7 to 4.6 seconds. In turn, a modal static nonlinear analysis was performed to obtain the capacity curves for each type of building, which were compared with the seismic demands according to the design provisions of the Peruvian seismic code E.030 and an average of spectra of acceleration records of severe seismic events in Peru and scaled in a range of 0.2T to 1.5T. Finally, the performance points for each building case were determined following the ATC-40 methodologies, finding that tall buildings with a rigid core have approximately twice the stiffness of buildings with an energy dissipation system, as well as having low ductility. unlike buildings with dissipators that have long ductility.
