Field Teams: Finale Emilia Viaduct 29-05-2012
Date: 29-05-2012 Category: Bridge Typology: R.C. Municipality: Finale Emilia Distance from epicenter: 10 km Damage Typology Transverse dislocation in some spans of the deck (approximately 20 cm); further transverse displacements could induce the complete loss of support for the beams of the deck which could directly lay on the top of the pier. The action of the seismic sequence […]

Preliminary Report on the 2012, May 20th, Emilia Earthquake
This report presents the results of a preliminary survey in the area affected by the May 20, 2012 Emilia, Northern Italy, earthquake. In this report, a reconstruction of the local seismic catalogues is presented, the damage to historical buildings, rural buildings, industrial buildings and reinforced-concrete buildings surveyed on May 21-22 is described, and a short […]
Effect of 8.2 Mw Iquique Earthquake on Tall Buildings
An 8.2 Mw Earthquake struck the Chilean coast on April 1st. The epicenter was located 95km NW of Iquique. There are many 20+ story buildings in the affected area with similar characteristics than those affected in the last February 27th 2010 Maule’s earthquake, such as a high shear wall density and 20cm thick walls with none […]

Preliminary Assessment of Structural Performance – RC Buildings
Compared to the 8.8M earthquake in 2010, the 8.3M earthquake did not caused important structural damage on reinforced concrete buildings (RCB). However, two more facts helped to reduce the effects of the recent event: the affected area is less densely populated and the energy released was a third of the 2010 earthquake, as explained in an article by Pascale Bonnefoy and Patrick J. […]
Illapel Earthquake: Housing
Figure 1. Reinforced concrete building structures presenting substantial damage in the nonstructural components of the first and second floors owing to the tsunami. Coquimbo. The dwellings in the affected area are mainly masonry structures (of one or two storeys), and the remaining dwellings are reinforced concrete structures, adobe structures and wood structures. Masonry structures […]
A Simple Evaluation Method of Seismic Resistance of Residential House under Two Consecutive Severe Ground Motions with Intensity 7
In the 2016 Kumamoto earthquake in Japan, two severe ground shakings with the seismic intensity 7 (the highest level in Japan Meteorological Agency scale; approximately X–XII in Mercalli scale) occurred consecutively on April 14 and 16. In the seismic regulations of most countries, it is usually prescribed that such severe earthquake ground motion occurs once […]
