Abstract

Shear wall frame buildings are commonly used in buildings ranging from about 8 to about 30 stories. Shear walls may be simple planar walls, several wall segments commonly are connected to act as a three-dimensional unit, then may enclose spaces in buildings, such as stairs, wells or elevator shaft. In this case, 18 story building with shear wall as planar has been analyzed. The portion of frame is less than 25 % as required in Indonesian standard there are 11.64% in X direction and 12.12 % in Y direction, so the results are compared with the condition if shear wall is released, hence, only boundary elements are placed and taken the maximum value by giving 25 % earthquake load. In the 100 % base shear acting on structure the value of column shear force has greater value at the bottom story of column than if shear wall is released and only 25 % base shear is given. The value of shear force at shear wall in the bottom story is greater in the bottom because there is void in that area. The portion of frame is less than 25 % as greater in the bottom because there is void in that area, so the greater shear force in the story is obtained. As the result, at the lower story the correction of scale factor less than one factor for all story can give the economical design.
