Findings in Civil Engineering Reported from T. Wright and Co-Researchers

2011 FEB 16 - (VerticalNews.com) -- "This paper conducts a detailed review of thernseismic hazard, inventory, bridge vulnerability, and bridge retrofit practices in the Central andrnSoutheastern United States (CSUS). Based on the analysis of the bridge inventory in the CSUS,rnit was found that over 12,927 bridges (12.6%) are exposed to 7% probability of exceedance (PE)rnin 75-year peak ground acceleration (PGA) of greater than 0.20 g, and nearly 3.5% of bridges inrnthe CSUS have a 7% PE in 75-year PGA of greater than 0.50 g. Since many of the bridges inrnthis region were not designed with explicit consideration of the seismic hazard, many of themrnare in need of seismic retrofitting to reduce their seismic vulnerability," scientists writing in thernJournal of Bridge Engineering report.
