Taiwan's vibration mitigation

VSL has designed, supplied and is installing the VSL-R damper system for a 25-storey residential building in Kaohsiung City, Taiwan. In total, 52 sets of VSL-R dampers are being installed from the 2nd to the 14th floors to mitigate wind - and seismic - induced vibrations and deformations. The project uses high wall-type units each containing a VSL-R damper. They are integrated into prefabricated steel panels and installed directly into the structure during construction.


Challenging transformation in Spain

VSL has completed the challenging first phase of work to transform the historic Sant Antoni marketplace in Barcelona. A new 12,000m2 joint-free voided transfer slab post-tensioned in both directions was built below the old building to support it during the construction of three underground levels underneath. Spans of 30m by 20m combined with design loads of 24kN/m2 and the need to retain the existing steel structure meant that the Sacyr-Scrinser-Copcisa JV and VSL had to develop a tailor-made solution. Phase 2 will see VSL working on the PT slabs for the new underground levels.


Quieter crossing in Slovakia

Installation of a post-tensioned deck was chosen as a quieter alternative than the traditional steel for a rail bridge crossing the Váh River in an urban area of Trenčín in Slovakia. The new bridge is being built as part of the upgrade of the Nové Mesto nad Váhom – Púchov railway. The project for Slovak Railways is being co-financed by EU funds and built by Bögl and Krýsl to a design by Betoning. The seven-span viaduct is 340m long and is being constructed by the balanced cantilever method. VSL is supplying tie bars and post-tensioning, together with PT-Plus® ducting.
