The Zygos Bridge in Limassol carries the main B8 road across the Limnatis river where it enters a large reservoir.
The bridge required a major reconstruction work in 2013. The work involved the complete removal of the bridge deck and of the upper section of the existing piers and abutments, and the construction of a new, wider deck with enhanced load-bearing capacity on the newly-strengthened piers and abutments.
In order to enhance the bridge’s ability to survive a strong earthquake, it was considered necessary to seismically isolate the deck from the piers and abutments beneath.
mageba supplied 56 LASTO-LRB lead rubber bearings to support the new deck of the renovated bridge.
In addition to supporting the deck like standard bearings during normal service conditions, these will also isolate the bridge from damaging ground movements during any earthquake that might occur.
The isolators each have a diameter of between 450 mm and 550 mm, and a height of up to 244 mm.
Prior to installation, seismic testing, in accordance with EN 15129, was carried out at the Eucentre facility in Pavia, Italy.
