For one motorway project in Romania, the alignment has to cross an artificial lake that was made for drying a former swamp. The alternatives considered were crossing the lake with a bridge or with an embankment. According to the geotechnical investigations, the soil in the area consisted of soft saturated clays of 10-18m followed by marle. Crossing the lake with a bridge involved raising the vertical alignment of the motorway to nine meters above ground level in order to ensure the clearance for the maintenance of...

The Giurgiu-Ruse Bridge, also known as ?The Friendship Bridge?, is one of the two bridges over the Danube River, which links Romania and Bulgaria aside with the Calafat ? Vidin Bridge. Between 2014 and 2016 the Romanian side of the Giurgiu-Ruse Bridge was retrofitted. After finishing the works, static and dynamic trials were done in order to attest the behavior of the structure under test loads. The superstructure of the access viaducts is made up of independent upper carriageway steel decks, simply supported beam...

Romania is an active country from a seismic point of view, every year occurring around 250 earthquakes, many of these of a medium to strong level. This is one of the reasons why the seismic design of bridges is very important in Romania. The seismic provisions applied in Romania evolved from P100 - 92 to P100 - 2013, containing major changes regarding the ground acceleration and corner period, but also regarding the structural details. The cantilever method for prestressed concrete bridges has obvious benefits for...

For the bridges under rehabilitation, especially for cable stay and suspended structures, situations that can lead to the increase of strain in the structure may occur during construction works. Because of that, monitoring the way the bridges behave during works becomes necessary. Monitoring them during rehabilitation under traffic is essential, because alarms are triggered when accidental actions take place or when certain strain values are exceeded. The bridge on DN39 over the Danube пїЅ Black See channel in Agi...
