| description | One of the methods of resisting to earthquake forces and its undesirable effects on structures is the use of seismic isolators. Investigations on the seismic structure have been initiated by researchers since decades, but so far no study has been done on the subject of this research. Therefore, in this study, the seismic behavior of an asymmetric slip structure with a moment frame system is affected by the horizontal component of the earthquake with Considering the effects of soil and structure interaction have been investigated. In order to achieve the main objective of the research, one, five, and ten stories irregular structures (40% irregularity) are considered with seismic isolator R-FBI located on type II, III and IV soils. Also, for irregular effect analysis, irregular structures of 20, 40 and 60 percent were compared to the regular model. In order to obtain the results of the research, the finite element method has been used with modeling of nonlinear materials and performing dynamic explicit analysis. The results of the study showed that, by changing the type of soil (in accordance with the 2800 Standards), the displacement and acceleration of the structural changes considerably. This change for the conversion of II to III soil was 87.2%, 36%, 4.1%, and in order to convert the soil II to IV, 19.1%, 3.1% and 30.7%, respectively, to change location of the upper storey of the structure is 1, 5 and 10 stories. Also, the acceleration of the upper storey of structures of 1, 5 and 10 stories for converting II to III are 2.18%, 3.2%, and 43.2% respectively, and in order to convert II to IV are 51.5%, 40.5% and 57.4% respectively. |
