Observations from EERI/PEER Team
From EERI/PEER Team: Masonry Damage Figure 1. Facades of unreinforced masonry structures show cracks varying in severity, from loss of plaster to separation of the walls from the structure (Figure 1). In this last case, the structural integrity of the wall, the load-bearing system, is compromised. Some of the structures in downtown […]
Observations on RC construction from EERI Team
In the last 25 years L’Aquila and its province were considered to be in the Class 2 seismic area of the building code and these buildings were designed for a horizontal acceleration of 0.25g. In the epicentral area maximum accelerations up to 0.67g were measured although a recording station went off scale at 1g (see […]
EERI/PEER team visits San Salvatore hospital
During our (limited) site visit we observed very little structural damage. Unfortunately the structural damage that did occur is located in crital areas. There is severe column damage in the farmacy area, which is considered to pose a collapse hazard. Operating theaters are located at the floor above the farmacy, and as a result could […]
Onna vs. Monticchio
Figure 1. Onna. Monticchio and Onna are about a mile apart, and have a similar building stock of stone masonry buildings in the historical centers. It is interesting to see how different these two villages performed, given the structural similarity. Onna suffered badly in the earthquake. Almost all buildings in the historical […]

Performance of Dutch Colonial Era Buildings
These art deco style buildings were an integral part of the original spice trade routes, using the Batang Arau as a trading port. The structures in this area are mostly tall two-story buildings, built with unreinforced brick masonry walls usually two-wythes wide. The buildings have wood floor and roof truss framing, with no substantial connection […]
Performance of Hospitals: Bunda Medical Centre
Both towers suffered extensive damage in the earthquake, though neither is in danger of collapse. The hospital staff has evacuated both buildings and has erected a tent in the parking lot to provide clinical services. One of the nurses told us that everyone, including patients, were able to safely evacuate the buildings after the earthquake […]
