Abstract - Recent earthquakes caused severe structural damage to a number of new structures, which highlights how crucial it is to prevent abrupt changes in lateral stiffness and strength. Numerous existing reinforced concrete buildings are susceptible to damage or possibly collapse after a powerful earthquake, as evidenced by recent earthquakes that happened. While soft story damage and collapse are most frequently seen in buildings, they can also occur in other kinds of structures. The concrete columns in the lower level behaved like a soft story during the earthquake since they couldn't offer enough shear strength. Adding the appropriate bracing to soft storeys of a building is typically the most cost-effective retrofitting method.
Key Words: retrofitting, soft storeys, bracing, earthquakes.
