15,000 buildings severely damaged or collapsed as of 8 am PDT 4/7/09. About 2/3 thirds of the buildings in L’Aquila were either damaged or destroyed. Mostly unreinforced masonry composed of rubble, stone, brick, and hollow clay tile masonry units suffered the worst damage. Several more modern, nonductile concrete frame buildings collapsed. One concrete frame with URM infill severely damaged. Corrugated steel roofs and horizontal wood flooring systems common in URM buildings. 28,000 estimated to be homeless and staying in temporary shelters as of 6 am PDT 4/8/09. Others have found refuge with friends and relatives. The region was initially developed in the 13th Century and has many historic structures.

Do you have a collection of building photographs available?
Not yet, we hope to have more up in the next few days.
Please clarify the line where you state that “Several more modern, nonductile concrete frame buildings collapsed”. What was the non ductile feature of the of the concreter frame construction that failed?
thanks
