Description

Reinforced concrete coupled shear walls are one of the systems commonly used in medium and high rise structures to resist lateral forces. The aim of this paper is to carry out an assessment regarding the impact of reinforced concrete coupled shear walls in the global behavior of the structure. Further, will be studied the efficiency of coupling beams, on the behavior of these walls, taking in consideration that depending on the stiffness of these beams, the walls can act as isolated walls, or interact with each other as a single system. Specifically, it will analyze the impact of variation of coupling beam‟s height and length, on coupled shear wall system performance, and plan ways of positioning of these walls. Among others it will also analyze the Coupling Degree degree of these beams. Important part of this topic approach, is the type of detailing and construction of these connecting beams of coupled walls, which has its own, because of the function to be performed, and the difficulty of realization in practice. Further in this study, we will see redistribution of internal forces on shear wall and their coupling beams due to wall-beam interaction, by using ETABS and SAP2000 programs. For the analysis of reinforced concrete coupled shear walls system, we will use “Modal Response Spectrum Analysis” and non-linear. ”Push-over analysis” . We will compare the following parameters for the building with coupled shear wall with various depth and length of coupling beam, we will compare the following parameters:

Lateral displacement at each floor levels, Time period of the building, Maximum deflection at roof level, Seismic base shear for models, Story drift of the structure, Storey shear, Overturning moments.

Keywords:

Reinforced concrete, structure, walls, beams, performance etc.
