  7. Abstract:
  8. Shear walls are constructed to counter the effects of lateral load acting on a structure. In residential construction, shear walls are straight walls that typically form a box which provides all of the lateral support for the building. When shear walls are designed and constructed properly, and they will have the strength and stiffness to resist the horizontal forces. Thus shear walls are one of the most effective building elements in resisting lateral forces during earthquake. By constructing shear walls damages due to effect of lateral forces due to earthquake and high winds can be minimized. Shear walls construction will provide larger stiffness to the buildings there by reducing the damage to structure and its contents.
    The objective of this study is to propose a way to optimized positioning of shearwalls in steel structures to withstand seismic forces. Three positions will be considered for placing shearwall inside the steel frame: inside frame and interacting with columns, inside frame and non-interacting and eccentric shearwall with an offset equal to thickness of the wall from the frame.
    These positions are investigated in 4, 10 and 16 story buildings subjected to linear static loading according to Iranian building code (2800). The additional parameter of wall thickness is taken into account for having better point of view. The shearwalls are designed according to ACI318-05 and the most cost effective design will be mentioned as optimized design
