| description | Steel shear wall can be reinforced with concrete layer or steel stiffeners. Steel shear wall without stiffeners is named special steel shear wall. Capacity of special steel shear walls before buckling is insignificant because of thin plate or being unreinforced. Several studies have been done on steel shear walls, but because of the confusion that exists in most design codes such as our country code, it is not provided. To eliminate some of the confusion, in this paper focused on the behavior of special steel shear walls. This study, a 10-storey building was designed with special steel shear wall. The upper story of the structure was examined. The models are one span and one story whose length of span (inside into columns) and a height of story (the inside of the beams) are 3 m. Beams and columns are IPB280 and thickness of web plate is 2 mm.Finite-element modeling, boundary conditions, and loading procedures were validated by comparing published test results with the corresponding analysis results. Two single stories tested by Sabouri-Ghomi et al. and Valizadeh et al. were modeled using the finite-element program. The material properties reported by the original researchers were used in analyses of finite element models. The results show that there is little difference between the experimental and finite element results. One of the problems of steel wall with opening is causing stress concentration at the corners. Corners are the first place for cracking. One of the solutions that has been studied in this paper is creating a curvature in corner. In addition, effect of opening position on the period and buckling force and wall resistance is studied. The results indicated that opening on the wall increase time period. Corner opening increases period more than central opening does. Not only opening on the wall decrease buckling force, but also decrease wall resistance. If opening is closer to the wall center, the resistance of steel shear wall will be reduced further. |
