We are proud to announce that we have positively completed a fatigue and static test carried out at the Politecnico di Milano, according to Fib Bulletin 30, over a stay cable, made of 7 strands galvanized, waxed and hdpe coated, provided with a multi-tube saddle type 7TSS-T. The 2 million fatigue cycles have been completed without wire failures and subsequently a static test has been performed, leading to a maximum load exceeding 98% of the nominal breaking load of the cable. This brilliant result comes after nearly 6 months of continuous work for the design, manufacturing, installation and test execution. Congratulations to our technical office working group!

On the 12th July 2016 TENSA obtained a new improved European Technical Assessment (08/0012) on its multi-strand system, issued by the French TAB Cerema. The assessed system now includes the coupler anchorage type MTG, from 4 up to 37 strands type 15,2 and 15,7 mm diameter strand. The new ETA also provides updated information on the improved performance of the system, allowing a complete and satisfactory support to design and construction activities related to PT. The brilliant achieved result confirms again the high levels of performance guaranteed by TENSA post-tensioning system. www.tensainternational.com

CASE STUDY - Kingdom of Saudi Arabia, Wadi Hanifa #Challenge: Constructing a viaduct that crosses the 120 km-long Wadi Hanifa valley in the Nejd region in central Saudi Arabia. The deck is a precast segmental concrete box girder with internal post-tensioning, erected via balanced cantilever method. #Solution: TENSA supply: - 2.086 complete 12MTAI15 Internal post tensioning anchorages, including the full set of installation, stressing and grouting equipment; - materials required for the temporary bars post tensioning needed during the span assembly process; - POT bearings (TP), Shear Keys (TSK) and Shock Transmitter Units (TSTD); - approx. 64 m of TUBJ 400/S pre-regulated expansion joints (± 200 mm). #Outcome: The project has been successfully completed in one year. The time performance is remarkable, especially for erection rates out of the learning curve: one span (77 m long each) per week. www.tensainternational.com

READY FOR A NEW CHALLENGE - ITALY - Cable stayed bridge over the Crati river After designing, producing, supplying and installing two record-breaking Pot bearings (more than 16.000 kg each) combined to an hysteretic device with elasto-plastic behavior (vertical capacity of 60.000 kN and lateral capacity of 20.000 kN), we are now ready for the next challenge: in the next few months we will supply a couple of giant stay cables, each containing 169 strands (breaking load 47151 kN). The two back stays, installed between top and foundation of the inclined pylon having height 90 m, will balance the stayed-deck having length 110m, width 24m. www.tensainternational.com

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
