Information from WG 7

Workshop:  Technical presentation abstracts, London, 2011
C. Bucur - Earthquake and robustness case study concrete roadway viaduct
D. Sonda - Post-earthquake safety evaluation and strenghtening of buildings Haiti experience
J. Oviedo-Amezquita - Current situation of low-rise wall structures in Colombia
M. Gercek - Evaluatıon of seısmıc desıgn methodologıes ın Turkey
S. Dritsos - Earthquake damage a Greek perspective

S. Bousias - Hybrid Testing of Substandard Buildings Retrofitted Via RC Infilling

Field of activities and objectives
1.  Characteristic seismic failures
Identify, from a practical point of view, a list of worldwide characteristic seismic failures.  The parameters that lead to seismic failure of buildings and structures should be catalogued.
The objective here would be to develop practical ideas and advice that would lead to better design of new structures, identify the most vulnerable structures and upgrade existing structures in order to avoid seismic failure.

2.  Seismic code comparisons
Investigate the discrepancies and similarities between the various seismic codes adopted throughout the World. 
Concerning: Design of new structures, Assessment of existing structures and Upgrading and retrofitting.
The objective here would be to find a way to harmonise seismic codes and similar guidelines.  Grey areas of knowledge should be identified and areas for research could be proposed.

3.  Developing countries:  Vulnerability and simple strengthening techniques for non-engineered buildings
Examine rapid visual screening procedures to identify seismic vulnerability and investigate simple seismic strengthening techniques for non-engineered buildings in developing countries.
The objective here would be to find the most suitable way or ways to identify structurally deficient non-engineered buildings in developing countries and investigate and/or propose areas for research concerning simple retrofitting techniques in order to increase the seismic resilience of such buildings.

4.  Trends in seismic analysis
Closely monitor new state of the art trends in seismic analysis specifically in the areas of assessment and retrofitting.
The objective here would be to find grey areas of knowledge and, based on this, propose areas for research.
