Investigation of Behavior of Thin Steel Plate Shear Walls (Strip Model) Under Near and Far Fault Spectrums

In the latest three decades, steel plate shear walls have been considered as a resistant system against lateral loads and have been used in construction of modern buildings and retrofit of existing buildings in the world. In the latest years, researchers have seen different effects of near fault and far fault earthquakes. In this article, six simple steel frames which each of them has five 3, 5, 7, 10, 12,15 story spans and only their mid span has thin steel plate shear wall have been designed and then have been analyzed under near or far fault spectrum and Iran earthquake code spectrum. Results showed that base shear and roof drifts of short level frames (3 and 5 story) under the near fault spectrum, is less than the amount when they are under the far fault spectrum and Iran earthquake code spectrum and at medium level frames (7 and 10 story) and large level frames (12 and 15 story) the amounts mentioned above are vice versa. Also, base shear and roof story drift of steel plate shear wall which were investigated under far fault and Iran earthquake code (2800 provision) spectrums, are very proportionate with each other.
