Abstract
Steel shear walls that are used in two (thin and thick) forms, are innovative systems for resistance against lateral wind and earthquake loads. The thin type of steel shear wall has recently attracted the researcher’s interests. Due to good performance of this type of lateral resisting system (for example high stiffness, high ductility index and very much energy dissipation) it can be used for retrofitting of vulnerable structures. In this paper describing some tests on retrofitting a steel frame by a steel shear wall, the advantages and possibility of retrofitting vulnerable structures have been investigated and interaction of the frame and steel shear wall at different stages of loading has been studied. In the tests it was observed that for increase in the load carrying capacity of the shear wall, it is better to use stiffer columns and for increase in energy dissipation, more flexible columns are required.
