| Abstract: | The great Wenchuan earthquake,which measured as 8.0 Ms and occurred on May 12,2008 in Sichuan province of China,has caused severe damage to many highway bridges and also left us with valuable information that can be analyzed to reduce potential losses associated with future earthquakes.The Lessons learned from Wenchuan seismic damages of highway bridges were summarized.It is believed that special attention should be paid to(1) bridge seismic response and unseating damages subjected to near-fault ground moti... |
