Earthquake Damage Estimations of Buildings in a Typical North Lebanon Village.

Abstract eng:
Bechmezzine is a typical village of Koura region in North Lebanon. As Lebanon is considered a seismic area, the earthquake hazard for the region was defined. Probabilistic hazard maps were digitized and presented. Moreover an adequate attenuation relationship for the Middle East region was implemented, and used to generate the deterministic hazard map of Beshmezzine for a specific scenario. A ground survey was led in order to gather the data of the village buildings, and then structural vulnerability functions were adequately chosen and assigned. The earthquake-induced building damage was modeled through Ergo platform after suitable needed files were prepared through the Geographic Information System. The earthquake building damage of Bechmezzine is assessed in terms of likely earthquake scenarios, and final results were offered. It was obtained that the unreinforced masonry structures type is the most vulnerable to earthquakes followed by the reinforced concrete frame structures type. It was recommended to reinforce masonry buildings, to add shear walls to concrete frame buildings, and to follow strictly seismic codes for the construction of new buildings. This prototype study aims helping adequate authorities and the Lebanese government to take possible risk-mitigating actions, and thus increase the resilience of Beshmezzine village.
