Stiffness and strength degradation of steel shear walls having an arbitrarily-located opening

Behavior prediction of corrugated steel plate shear walls with openings

“…It is observed that opening location has a tangible effect on initial stiffness and ultimate strength of simple SSW. However, opening location does not have a significant effect on the response of stiffened walls [13].…”

“…Numerous studies have been conducted to investigate the lateral resistance, stiffness, and buckling behavior of shear wall systems and to propose prediction models [11][12][13][14][15][16][17][18][19]. Typically, stiffeners around openings are introduced into the shear wall design to limit the shear buckling and preserve the shear capacity of plate.…”

Prediction of the Load-Bearing Behavior of SPSW with Rectangular Opening by RBF Network

“…The application of this system compared to reinforced concrete shear wall (RCSW) system has increased in the past few decades, due to some advantages, such as lower weight, cost-effectiveness, and proper performance [5], which make some designing codes to add it as a suitable lateral load-bearing system [6,7]. SPSW diminished the amount of steel in the construction of new buildings and it is lighter than the RCSW system [8,9]. Moreover, as a retrofitting technique, SPSW can be easily installed in critical parts of the buildings [10,11].…”

“…Although experimental and numerical researches have been done to investigate the lateral load-bearing behavior of the SPSW with different shapes of opening and different areas, more studies are required to investigate this issue's effects [9,17,[19][20][21][22][23][24][25][26][27][28][29][30]. A short description about the previous researches are presented in Table 1.…”
