6) The results of this study indicate that the development of the soft-storey phenomena brought on by earthquakes depends critically on the positioning of infill walls. Column stiffness should be employed to control and restrict the inter-storey drift ratio in order to avoid soft-storey collapse. 7) Regardless of column strength, open-ground buildings are susceptible to soft first-storey issues even in low seismic zone areas. This highlights the importance of incorporating infill walls in the construction of reinforced concrete structures.
