چکیده مقاله :
The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than other systems because of adequate stiffness, ductility, and more energy absorption. The system of steel shear wall with corrugated sheets has been offered as an innovative system, since the construction of panels for hard-set steel shear wall is expensive and also it causes the increscent of weight construction. This type of system has been developed using of hard outer plate from geometry of corrugation shape that has better buckling strength than hard-set and flat case in this study. This study is conducted to compare the strength and energy dissipation capacity of three different steel shear walls: unstiffened, trapezoidally vertical corrugated and trapezoidally horizontal corrugated under vibration load of AISC 341-10 instruction with 100mm movement. The results reveal that although the ultimate strength of the unstiffened model is nearly 17% larger compared to that of the corrugated models, energy dissipation capacity of the corrugated models are approximately 52% larger compared to the unstiffened model.
