Comparison between dynamic nonlinear analysis with ASCE 7-10 and ASCE 7-16 in concrete frames with viscous dampers incorporated

During the last few years, different methodologies have been developed for the analysis of the structural seismic response, such as the performance-based design, the systems of energy dissipation, seismic isolation. Based on these efforts, a number of devices, known collectively as protection systems have emerged. They are divided into three types of systems: passive, active, and semi-active. Passive systems dissipate energy through friction, viscous fluid dampers, and inelastic behavior of the material, among others. On the other hand, active control systems can be implemented by applying time varying forces to counteract those imposed by the excitation. which can be active, passive, semi-active, active, etc. This paper presents the response of the structure when it enters the nonlinear range and is being controlled by the Viscous Damper. To obtain the nonlinear response of the structure system through numerical simulation are used the Methodologies of ASCE 7-10 and ASCE 7-16. To examine the behavior of the structures and the application of each methodology, simulations using concrete frames of 5, 7 and 11-story buildings were performed. The models were subjected to the horizontal components of different earthquakes, for the ASCE 7-10 were used three earthquakes, for the ASCE 7-16 were used seven earthquakes. These seismic records are subjected to a matching process to obtain records that match the corresponding building code design spectrum for a high seismic risk zone. The history displacement and acceleration results were compared with those obtained with the uncontrolled structure with nonlinear behavior.
