Peruvian protection
Seismic protection of buildings and bridges continues to grow in significance across Latin America, as demonstrated by many recent mageba projects – such as the supply of shock absorbers for the Shougang Building in the Peruvian capital, Lima.
While mageba’s past projects in Peru – such as Puente Nanay, which provided road access for the first time to the city of Iquitos – have tended to focus on connecting people, the recent Shougang Building project in Lima had the purpose of protecting them. To enable the existing nine-storey building to survive a strong earthquake and protect the structure’s users, it was decided to retrofit RESTON®SA shock absorbers (seismic dampers) at 28 locations throughout the building. The dampers were designed by mageba with various load capacities (670 kN, 1100 kN and 1500kN, depending on the location in the building) and with a stroke of +/- 125mm. Following successful testing (both Initial Type Testing [ITT] and Factory Production Control [FPC]) at the SISMALAB testing laboratory in mageba’s Shanghai production facility, the devices were shipped to the construction site in Peru. mageba’s project team also came to Lima to provide installation training, thereby ensuring the success of the project’s completion and the safety of the building and its users during future earthquakes – a very worthwhile investment in the future.
