Abstract

Observations from past earthquakes and studies conducted by various re-searchers show the effect of facade on the seismic performance of the structure. Structure, veneer wall and faced need to be stable and inde-pendent in their deformation. The most important goal in the upcoming study is to investigate the effect of materials on the in-plane behavior of external walls and building facades based on the existing common imple-mentation methods. Based on this, 3 samples of Cyclic lateral loads were tested in a controlled manner under displacement and the results of their behavior in terms of form, failure patterns, cyclic curves, cover, bilinear, ductility, reduction of equivalent hardness were investigated. The results of the analyzes showed that adding a facade to the structure, depending on the type and characteristics of the facade materials, has a significant effect on increasing the initial stiffness in range of 4 to 6 time and resistance in range of 2 time. Facade isolation reduces interframe damage and also re-duces facade damage and adverse interframe-frame interaction it seems that the seismic performance of the brick facade is better compared to the stone facade and has less effect on changing the seismic performance of the structure. Key words: facade isolation, seismic performance, brick fa-cade, stone facade
