Abstract

Buildings adjacent to each other may create risks during earthquakes, due to catastrophic structural response. This phenomenon is referred to as the IMPACT of non coherent vibration of adjacent buildings that are not constructed far enough apart. Considering that Iran is located on an active seismic belt, and with due regard to the need for safety, due to the expansion of towns and villages as well as retro t buildings, it is obvious that research is needed regarding the risks of injury during seismic hazard. The simplest way to cope with this phenomenon is to construct buildings of sufficient distance from each other. However, this is not always applicable, and other means are required to reduce the IMPACT of this phenomenon. One of the most modern methods of applying seismic dampers is necessary resistance against lateral forces using energy applied to the amortized and maintaining structures, known as energy dampers. Fluid viscous dampers are passive ENERGY DISSIPATION systems for seismic rehabilitation of old buildings. These dampers are uniform at all levels with the same scrollable frame placed between them. According to energy intake, the damper at each floor number was optimized and linear spring elements were used to model the IMPACT of the gap. For analysis of nonlinear dynamical performance, 3D software was used and the main structural elements were made of plastic. This study showed that the performance within the frames of the viscous damper significantly reduced the IMPACT ENERGY DISSIPATION rate, and the distance between the IMPACT energy absorption. For a VISCOUS FLUID DAMPER, the amounts of energy absorbed by the damper at all distances are almost identical.
