Vulnerability Assessment of a Heritage Structure Subjected to Blast-Induced Ground Motions

Research at Kakatiya Rudreshwara (Ramappa) Temple, Telangana, revealed that the temple's structure is resilient to blast-induced ground motions. The study found that high-frequency vibrations from nearby blasting at the Devadula Lift Irrigation Project were significantly filtered by the soft clay bed beneath the temple, resulting in minimal shaking within the heritage site. This suggests that such structures may be less vulnerable to damage from controlled blasting than previously assumed. The investigation employed velocity meters and accelerometers to measure subsurface and ground vibrations, providing quantitative data on vibration intensities and their impact on the temple's stability.
