Performance evaluation of low-rise infilled reinforced concrete frames designed by considering localeffects on column shear demand

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 5,   Pages 686-703 doi: 10.1007/s11709-023-0937-2

Abstract: The interactions between reinforced concrete (RC) frames and infill walls play an important role in theInfill walls can increase the overall lateral strength and stiffness of the frame owing to their highHowever, local wall-frame interactions can also lead to increased shear demand in the columns owing toThe proposed method can eliminate the column shear failure from the building.
