  • Patent number: 11091926
    Abstract: A building earthquake resistance structure includes an integrally connected roof support frame, used for supporting a roof of a building independently from walls of the building; a plurality of support columns, fixedly connected to the roof support frame; an annular trench, arranged in the ground around the building; an annular damping frame, arranged within the annular trench, lower ends of the support columns being fixedly connected to the annular damping frame; a plurality of dampers, arranged between a bottom portion of the annular trench and the annular damping frame. An earthquake resistance method for the building earthquake resistance structure prevents damage caused by the roof collapsing during an earthquake by supporting the roof of the existing building in the ground via the support columns. The building earthquake resistance structure is easy to construct and suitable for transforming traditional old buildings.
