Özet

Earthquakes are considered among the most destructive natural hazards worldwide. Regardless of the period in which they occur, earthquakes may cause severe damage or collapse of numerous structures, resulting in significant casualties and substantial economic losses. Post-earthquake damage assessments generally focus on primary structural components such as columns, beams, and shear walls, whereas staircase systems are often regarded as secondary elements and therefore neglected. However, staircases are structural components that can significantly influence the seismic behavior of buildings. Staircase openings may create short-span regions, while stiffness irregularities caused by surrounding infill walls and the interaction between the staircase and the structural system under seismic loading can alter the overall damage mechanism depending on the location of the staircase within the building and may lead to unforeseen torsional effects during the design stage. Furthermore, several researchers have reported that, depending on the staircase configuration and structural system layout, additional shear forces and bending moments may develop in columns adjacent to the landing, whereas internal force demands in other columns may decrease. In this study, staircase damage observed in buildings located in Malatya following the Kahramanmaraş earthquakes was investigated. The obtained findings were evaluated through a holistic approach considering parameters such as concrete and reinforcement quality, probable construction period, number of stories/building height, and building layout characteristics within the parcel. The results indicate that staircase systems should not be overlooked in seismic performance assessments, and they highlight the importance of a more comprehensive evaluation of these components within the existing building stock.
