چکیده :

Focusing on the importance of resistive structure designing against dynamic loads such as earthquake load and in capability of the designing methods which are based on the force to predict the nonlinear behaviour of member affected by nonlinear virtue of materials. In recent years the tendency of engineers and designers to use methods of designing based on displacement and behaviour (designing according to performance) has been increased. Because of being economic, and easy to accomplish and accessibility of the building material, nowadays we see a lot of masonry structures in villages and towns. In other hand Iran's location on the potential earthquake belt of alpine show the importance of studying about seismic behaviour and vulnerability in this kind of structures. Studies on masonry buildings after earthquake shows that fragility of materials and non continuity of these buildings are main factor of destruction at the time of earthquake, There are similar damages occurred by earthquake on these structures Regarding to kind of construction of these structures. In this study, some tied walls have been modelled with software and with relevant accelerator suitable with geology conditions under dynamic analysis to research on the Seismic Vulnerability and performance level of confined brick walls. Results from this analysis seem to be satisfactory after comparison of them with the values in Code ATC40, FEMA and standard 2800 of Iran.
