چکیده مقاله:

This report is made on basis of a site survey on almost all bridge structures located in the quake-affected area. By the inspection of damaged or collapsed bridges is clear that a large number were designed long time ago. Another important factor to be considered is that almost all of collapsed structures had pot been retrofitted to increase their resistant capacity against large earthquakes. Finally, this earthquake showed more than ever, the effect of vertical acceleration on the failure mechanism of collapsed structures.
