The Ecuadorian “Sociedad de Lucha Contra el Cancer” (SOLCA) was established in 1951 in order to treat and prevent cancer and has grown to become one of Ecuador’s most important health institutions, with facilities across the country. The society’s new hospital in Guayaquil, the country’s largest city, which is currently bring constructed, has been designed to protect it from damage during earthquakes. This is being achieved by isolating the main above-ground structure from the kind of strong ground movements that might arise during an earthquake.
In order to isolate the above-ground structure from violent ground movements, it is supported on an array of Lead Rubber Bearings (LRB), which function as regular bearings in normal circumstances but which provide critical seismic isolation properties (damping, energy dissipation and re-centering) during an earthquake, preventing the supported building from being destroyed. For this purpose, mageba has supplied sixteen LASTO-LRB seismic isolators, each with a movement capacity of 80 mm and a vertical load capacity of 1,000 kN.
