ROLLING ENERGY-DISSIPATION AND SEISMIC-ISOLATION RING BEAM FOUNDATION FOR SUPPORTING SPHERICAL TANK

A rolling energy-dissipation and seismic-isolation ring beam foundation for supporting a spherical tank. The foundation comprises an upper rolling steel ring beam channel body (5), a lower rolling steel ring beam channel body (6), steel balls (7) and a rubber trim strip (8), wherein the lower rolling steel ring beam channel body (6) is disposed on the ground, and the cross section thereof is a groove open upwards; the upper rolling steel ring beam channel body (5) is disposed above the lower rolling steel ring beam channel body (6), and the cross section thereof is a groove open downwards; and eight steel balls (7) are uniformly arranged between the upper rolling steel ring beam channel body (5) and the lower rolling steel ring beam channel body (6), and the rubber trim strip (8) is arranged around the steel balls (7). L'invention concerne une fondation de poutre annulaire de roulement d'isolation sismique et de dissipation d'énergie pour supporter un réservoir sphérique. La fondation comprend un corps de can
