Seismic Assessment of the Archangeloi (Başmelekler) Church in Kumyaka, Türkiye

This study describes the seismic assessment of Archangeloi (Başmelekler) Church in Kumyaka (Sige), Türkiye. The is an important religious monument that has survived to present day from eighth century. Through field surveys, structural system, damages and masonry texture were determined. Pushover analysis was performed with OpenSees software, which advanced nonlinear capability. Damage TC3D material damage model features used, allowing a more stable effective application mixed implicit–explicit analyses. Displacement-based pushover analyses different control points, patterns, ultimate strength reductions obtained effectively. reflected structure’s expected behavior, especially its post-ultimate failure owing model’s capacity. Kinematic determine overturning mechanisms. Due assumptions pre-assigned mechanisms, lower multipliers kinematic than analysis. Under loading, structure did not satisfy required performance targets. Extensive occurred throughout structure, even at lowest levels. selected modeling/analysis method this church’s reflect behavior.
