evaluation of low-rise infilled reinforced concrete frames designed by considering local effects on column

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

Abstract: However, local wall-frame interactions can also lead to increased shear demand in the columns owing tothe compressive diagonal strut force from the inll wall, which can result in failure or in serious situationsIn this study, the effectiveness of a design strategy to consider the complex infill wall interactionframes and the failure modes were compared with those of frames designed without considering the infill wallThe proposed method can eliminate the column shear failure from the building.
