MAURER supplies expansion joints, bearings, and dampers for bridge and viaduct projects. One of MAURER's global projects in this area is a bridge project in Croatia. The total length of the bridge is 2404 m. Its height is 55 m, and it comprises five central spans, each 285 m long.
For this project, MAURER developed and manufactured 32 spherical bearings. Of them, 16 bearings can withstand horizontal loads of up to 19 MN. One of the challenges for MAURER in this project was the vertical installation of these bearings. The remaining 16 bearings had to withstand horizontal loads of up to 33 MN.
All 32 bearings allow for sharp displacements of up to 1.3 m during a strong earthquake. The longest bearing is 3 m long, 1.2 m wide, and 330 mm high.
For this project, 2 expansion joints were also supplied. Each expansion joint consists of 14 profiles. One of the important tasks set by the customer before MAURER was the maximum corrosion resistance of the expansion joints. Therefore, MAURER chose a hybrid design. I.e., the upper part of the expansion joint was made of special stainless steel (specially designed for wear protection), and the lower one was made of structural steel. This ensures maximum protection of the expansion joint surface from wear.
