The reinforced concrete shear wall is one of the most commonly used lateral load resisting structural components in reinforced concrete buildings. The purpose of this study is to analyze the two independent shear walls, which are connected with coupling beams in the presence of lateral loads. When a lateral load acts on one side of the shear walls, due to the highly rigid nature of adjacent shear walls, most of the stress concentrated on the foundation beam, coupling beams, and foundation piles. Different types of foundation beam design and different foundation pile arrangement could affect the strength of the overall structure. This study is focused on improving the design of the foundation mat and foundation pile arrangement to mitigate the design risks associated with the coupling wall structure.This thesis uses STAAD.Pro to establish 16 variety of computer models of different mat foundations and different foundation pile arrangement to analyze seismic loads. The results reveal that a continuous intense, rigid foundation beam is essential for the coupled shear wall structure, and the appropriate pile arrangement can also reduce the bending moment and shear force in the foundation beam and coupling beam.
