The structural safety of the infrastructure stock is an important issue in modern seismic performance assessments. Following recent events, reports have highlighted increased vulnerability physical infrastructural assets, particularly for many bridges across Italian road and motorway network. Italy possesses one most complex intricate systems Europe which was constructed irregular territories t...

Abstract The number of bridges approaching or exceeding their initial design life has been increasing dramatically. Meanwhile, are withstanding an ever-increasing traffic volume, both in and weight vehicles. Analytical numerical models can predict bridges’ response to loads ultimate capacity with low uncertainties; however, such uncertainties increase as age due deterioration mechanisms. Non-de...

With the increase of traffic pressure on main roads in central areas major cities, new high-speed elevated corridors have become a way to relieve urban congestion. However, for prosperous areas, cast-in-place piers and cap beams cannot be used well due long construction period harsh conditions. At this point, prefabricated cover can solve above problems. actual engineering abroad, especially Af...
