This research explores the impact of ageing effects resulting from the corrosion of structural materials on fragility functions which are analytically derived for reinforced concrete moment-resisting frame buildings. These structures represent the predominant architectural typology in Türkiye. Initially, an examination is conducted on both in-situ and laboratory material testing results obtained from reinforced concrete buildings in Istanbul. These buildings were constructed between 1962 and 2004. The objective is to gain deeper insights into the extent of corrosion and its distribution within structural components. Subsequently, the degree of corrosion and its diverse manifestations are integrated into structural analyses. This is achieved by modifying the mechanical properties and constitutive models of materials using data acquired from literature-based experimental and numerical findings. To accomplish this, three-dimensional finite element models are developed for both low- and mid-rise buildings. These models adhere to the guidelines outlined in the 1975, 1997, and 2018 Turkish earthquake codes. The comprehensive analysis takes place within the OpenSees environment. The behavior of buildings in their original state and as they age is investigated using nonlinear dynamic analyses. These analyses subject the structures to strong ground motion accelerations which are chosen and scaled to accurately represent the seismic hazard level specific to Istanbul. In the process of deriving fragility functions, the study employs techniques such as multiple-stripe analysis and maximum likelihood estimation method. These methodologies contribute to a robust understanding of the vulnerability of the structures under consideration.
