Abstract

In High-rise buildings, by increasing the number of floors, designers are forced to use the Tubular system or to combine it with other systems. The “ Shear lag” phenomenon and also architectural problems due to the low distance between the columns are disadvantages of this system. Concentrically bracings due to their high shear-stiffness combining with Tubular system improve the behavior of this system due to the disadvantages mentioned. But the main disadvantage of this system is the sudden change of lateral deformation against wind and earthquake forces. In this paper, a new idea is introduced that uses a steel shear wall at the two ends of the frame and a General bracing between them. These two walls act as a strong moment anchor against overturning moment of building, and due to their high stiffness, absorb the major shear forces. So, the Shear lag decreases. The results show that lateral deformation is reduced in the proposed system, and the axial forces and bending moment also have a significant reduction, which indicates the high efficiency of this system.
