Seismic vulnerability of Himalayan stone masonry: Regional perspectives
2021
Abstract Stone masonry is one of the most dominant construction forms in the Himalayan region. Stone masonry construction has been used for centuries in the Himalayan region and other regions around the world due to their availability, low construction cost, and easy availability of construction workers. However, their performance during historical earthquakes has not been satisfactory, and on many occasions, collapse of the entire building or some components has caused enormous losses in terms of lives and properties. This chapter presents an account on the typology of stone masonry construction in Nepal in regional scale and develops damageability functions based on the historical damage data. Taxonomical variations in stone masonry are presented in a regional scale together with typical damage scenarios. Some insights in reconstruction and retrofitting of stone masonry buildings after the Gorkha earthquake are presented. A correlation between building collapse and fatality is also developed considering the damage statistics of some past earthquakes.
