•C-shaped walls subject to different loadings simulate isolated or coupled walls.•Bi-directional loading results in approximately 20% reduction of drift capacity.•Flexural strength loss from boundary element damage was impacted by load direction. Reinforced concrete structural walls are commonly use...
