DEVICE TO ENSURE LONGEVITY OF BUILDING STRUCTURES DURING SHORT-TERM DYNAMIC ACTION Russian patent published in 2011 - IPC E04H9/00 

FIELD: construction.

SUBSTANCE: device to ensure longevity of building structures, during the short-term dynamic effect, comprises a support from a lower metal element fixed on the support surface, and an upper metal element, where a building structure rests directly. Besides, one of these elements is installed with the possibility of vertical displacement, and a metal insert of round section arranged between the lower and upper elements. The lower and upper support elements are arranged as plates, and a metal insert is arranged in the form of a wrinkled insert and has a cross section in the form of a ring, besides, the wrinkled insert length is determined using the given dependence.

EFFECT: increased longevity of a building structure under various types of short-term dynamic loads, provision of building structure bearing capacity integrity, reduced material intensity.
