000019224 520__ $$2eng$$aPeru is located in the Pacific Ring of Fire, which is one of the regions of higher seismic activity in the world, so its history of devastating earthquakes is large, as well as the loss of lives and property damage. Structural engineers can not be oblivious to these losses, which is why it is necessary to raise the challenge of incorporating new technologies such as seismic protection systems in new and existing buildings as a feasible alternative. The concept of energy dissipation is a design strategy that can be used in new structures and seismic rehabilitation of existing structures. Therefore, researchers and engineers have shown interest in using energy dissipation devices as an efficient way to reduce the response of structures subjected to strong ground motions. In this research a method for the analysis and design of buildings with passive energy dissipation is proposed following the guidelines set by the American Society of Civil Engineers (ASCE) and Federal Emergency Management Agency (FEMA). The proposed method performs a nonlinear time history analysis (NLTHA), based on the philosophy of performance design proposed by the Structural Engineers Associations of California (SEAOC) across the Vision 2000 Committee. This method was applied to a building located in the city of Lima, Peru, which will be used as a Health facility. The building has a structural regular pattern in plan and elevation. It is a four-story reinforced concrete rigid frame structure, with stiffness below what is established by the Peruvian Code "Reglamento Nacional de Edificaciones" (RNE) [6] but with adequate resistance. According to the recommended levels of spected preformance for buildings proposed by the SEAOC, the building should have a Operational and Life Safety performance under earthquakes of 475 and 970 years of return period. The targets drift associated with each damage state of according to the Manual Multi-hazard Loss Estimation Methodology Earthquake Model (HAZUS-MH) are 0.0035 and 0.006, respectively. The building was design using the dynamic modal spectral analysis specified in the RNE. After that, a NLTHA was performed iteratively to the building with viscous fluid damper until reduced lateral drifts below the determined targets. In order to compare the structural behavior and the costs of construction by incorporating the building energy devices, a conventional solution was developed, that consists in increasing the size of the columns and beams until the building reaches similar lateral drifts. Verified that the conventional solution is more expensive that building unconventional.
