CASE STUDY – ITALY – L’AQUILA – Gagliardi Sardi building #Challenge: base isolation of the masonry building, severely damaged by the 2009 earthquake, using the retrofit approach, in accordance with regulations and preserving its historical value. #Solution: Tensa has used a combination of 53 high damping rubber isolators characterized by a limited horizontal stiffness to limit the input force, in parallel with 49 free sliding Pot Bearings to limit the torsional effects at the isolation interface and the global cost of the intervention. #Outcome: Base isolation retrofit has allowed Tensa in avoiding an invasive structural intervention above the ground level characterized by valuable architectural elements concentrating the work in the creation of sub foundations. This approach allowed to proceed with a simple conservative restoration guaranteeing the protection of an extremely important building both for national artistic heritage and for the city of L’Aquila. www.tensainternational.com

LIVE FROM CONSTRUCTION SITES - COLOMBIA - Proyecto Cartagena-Barranquilla y circunvalar de la prosperidad - Gran Manglar Viaduct. First pile driving test successfully completed! Here are the the last pictures from Cartagena, where Rizzani de Eccher, Deal and Tensa have implemented a environment-friendly solution for the construction of the longest bridge in Colombia. The innovative “top-down construction method” ensures the possibility of constructing the entire viaduct, including foundations, solely by accessing the section of the viaduct which has already been built. TENSA supply: - Pre-tensioning equipment (mono-strand jacks + hydraulic pump equipped with lifting device for jacks movimentation / 5 sets) - Bushes, wedges and couplers for pre-tensioning - Post-tensioning materials for piers - Bearings and joints www.tensainternational.com

READY FOR A NEW CHALLENGE - ITALY - Ispica, Rosolini, Modica - Salvia Viaduct (A18 - Siracusa-Gela) The two-lane and 28 spans - 54 ml length each - Salvia viaduct, will be erected using the balanced cantilever tecnique, which has been adopted only a few times in Italy so far. The infrastructure dimensions, as well as its extension, have required the design of significative bearings for both loads and sliding capacity, but it also had to fit the reduced dimensions of the concrete segments and piles. TENSA is supplying free sliding pot bearings (TPM), guided longitudinal bearings (TPL) and transversal constraints (TRT). www.tensainternational.com

CASE STUDY - Romania - Bucarest - Seismic isolation of Mihai Bravu Overpass #Challenge: pier head dimensions of the steel arch bridge were not sufficient to guest the lead rubber isolators size as designed in the original drawings. #Solution: Tensa suggested to change the isolator's round geometry to a rectangular shaped solution, providing the same performances as the original one. #Outcome: our solution permitted to switch the problem: instead of modifying and adapting the existing structure, we have designed a new isolator to suit the available spaces. www.tensainternational.com

SUCCESSFUL COMPLETION OF CRYOGENIC STATIC LOAD TEST ON PT SYSTEM - Laboratory of MPA (Materials testing and Research Institute), Karlsruhe (Germany) Once again, TENSA confirms its continuous effort in products development and testing towards higher levels of products’ performance! We have brilliantly completed a full scale cryogenic static load test in compliance with ETAG013 and SR 88/2. The complete tendon, made of 27 strands provided with 27MTAI anchorages, has been tested at the extremely severe condition of -196°C, providing a brilliant result in full compliance with the most stringent acceptance standards on the market. The achieved results provide again proof of the perfect suitability of our PT system for use in #LNGtanks and all applications where extreme cold conditions may affect the standard use of systems. www.tensainternational.com
