摘要

This paper describes an in-depth case study of St. Andrew’s Church (The Kirk), located in Chennai, India, focusing on its historical background, construction, past damages, repairs, and conservation methodology, with special attention to the steeple, adhering to ISCARSAH principles. A vibration study was conducted to ensure the safe resumption of the church bell’s operation. The Fourier Transform (FT) was employed to understand the response of the steeple to the bell vibrations. The results showed that the maximum PPV was 1.253 mm/s, which is within permissible limits as per codal provisions, indicating that bell operations can be safely resumed without posing any risk to the structure.
