- Abstract
Nowadays paying attention to the environment problems and also special attention and conservation to it, is very important in human societies. In this regard, the present research investigates the effect of using seismic isolation system at high-rise structures to retrofit with decreasing building construction material consumption by the approach of protecting the environment. In recent decades utilizing seismic separators to strengthen the structures against quakes has entered performance. The main goal in this method preventing direct transition of earth-quake force from the foundation to the structure. In the other word in seismic separation to confront lateral loads due to the earthquake, only to apply lateral rigidity of the structure. Against lateral loads such as wind load, or operation loads of some ingredients with lateral loads in the least need is suggested. In this method because the earth-quake is not entered the structure or a small share is transferred to the structure, it will have consequences such as reduction of the floors relocation, decreasing acceleration, decreasing structural and nonstructural damages, and finally decreasing materials usage, and environmental protection. Initially using a laboratory sample, selected from a steel frame, we payed to the procedure of modeling and validation results, by the method of limited components at ANSYS software, and in the following by modeling the structure of 15 floors, in existing and non-existing the separator and interaction between soil and structures and doing nonlinear dynamic analysis the systems operation, in consecutive cycles, is investigate. The results show the reduction of materials to protect the environment.
