Examining the Interaction between Shear Walls and Reinforced Concrete Frames in Tall Buildings using a two-dimensional model | Original Article

ABSTRACT:

Today, there is a pressing need to set aside arable land in addition to meeting rising demand for it to accommodate residential, commercial, and industrial development across the board. That's why there's a recent surge in the construction of skyscrapers. Wind and earthquakes exert lateral stresses on these high-rises. This research also makes an attempt to simulate the shear wall's interaction with the RC frame in two dimensions for buildings of 20, 30, and 35 stories. Two outside frames with shear walls are treated as a single frame with double stiffness, strength, and weight in the corresponding simplified 2-dimensional model. It is assumed that the internal frames without a shear wall have the same stiffness, strength, and weight, hence they are represented as a single frame. Every story in the model requires a stiff link to connect the frames. The lateral force distribution between the outside frame with a shear wall and the inside frame without a shear wall is examined using a 2-dimensional plane frame model. Analysis shows that up to the lowest seven or eight stories, the frame with shear wall bears more than half the load, and the bottom three stories bear almost 75 of the whole story's shear. This research examines a 30-story skyscraper with and without shear wall apertures. Specifically, dynamic analysis makes use of the response spectrum approach.
