Earthquake Retrofitting of “Soft-Story” RC Frame Structures with RC Infills
Applied Sciences, 2022 Multi-story, old reinforced concrete (RC) structures with a “soft-story” on the ground floor, sustain considerable damage to the soft story during earthquakes due to the presence of masonry infills in the upper stories.

Soft Story Design of Reinforced Concrete Structures with Masonry Infill Walls [PDF]
Journal of Rehabilitation in Civil Engineering, 2023 Based on the seismic design codes to prevent soft-story failure, columns of a soft story must be designed for amplified loads due to the discontinuity of braces or shear walls in that story.

Investigation of seismic response of asymmetric buckling restrained braced frames equipped with zipper struts [PDF]
Journal of Structural and Construction Engineering, 2021 One of the most important deficiency of buckling restrained braced frames is the concentration of lateral drifts in some specific stories and the soft story mechanism, under moderate to severe earthquakes.

Evaluation of Park-Ang Damage Indicator in collisions of two adjacent frames under the near-fault field disturbances [PDF]
Journal of Structural and Construction Engineering, 2021 Pounding of adjacent buildings during earthquake causes local and total damages in buildings. One of the ways to reduce the damage in pounding, is creating a separation gap between two adjacent buildings.

Evaluation of Using Strong Column-Weak Beam Requirements in Prequalified Welded Connections in Intermediate Steel Moment Frame [PDF]
Journal of Structural and Construction Engineering, 2019 Beams are genarally used to face bendind force and columns are used to face axial load. as the seismic load comes parallely with respect to earth surface. so the column faces the load pependicularly which is very risky for the column.
