ABSTRACT

Bayon temple, Angkor, built in late 12th century to early 13th century consists of sandstone-dry-masonry structures. It has been deteriorated possibly by rain, plant intrusion, settlements, and so on. Strong wind of more than 20 m/s was observed in the rainy season (JSA 1995), which may vibrate the structures either directly or via ground motion and eventually cause damage on them.
