A variety of structural systems have been proposed to improve the behavior of high-rise buildings. The perimeter frame system is one of the most suitable systems for supporting lateral loads in this type of structure. In the design of the building, attention should be paid to the deformation caused by the cut and, as far as possible, to reduce it. These deformations are referred to as shear delays. Past researchers in their designs have more than examined the effect of shear delay on simple columns. In this study, the effect of shear delay on a box with a cross section was investigated. Considering the hardness of the beams between the columns, creating a bracing frame and comparing the system with classified columns, the ASCE / SEI 7-10 shear slab reduction methods are considered. For this purpose, the 40-story building is three-dimensional and in accordance with the standard
Chassis is modeled with increasing difficulty, column sorting and bracing frame .ETABS2015 in software
The structure has been designed and compared with conventional long structures to the effect of these factors on shear slab. The results show that each of the mentioned factors has reduced the significant amount of shear slabs, while the effect of increasing the hardness of the peripheral beams on the reduction of lamina was higher.
