SU1423694A1 - Screen for protecting a structure against seismic action - Google Patents

Abstract

The invention relates to shields for protecting structures against seismic effects, allows for increased seismic insulation of structures. The screen is made in the form of a trench 1 located around the structure 2. The trench contains flat walls of CZ 3 adjacent to the surface of the trench remote from the building, as well as the inner wall 4. adjacent to the nearby building of the tranpliy surface. and bottom wall 5, adjacent to the bottom of the trench. The inner and lower walls constitute the corner wall. The outer wall is connected to the lower wall 5 by means of a cylindrical hinge 7 through a system 6 of dry friction. The trench is filled with liquid 8 and compressed gas 9, the pressure of which is regulated by valves 10. The top of the trench is blocked by a damping gasket I. The outer and bottom walls are made with anchor triangular projections 12. 2 Cp. f-ly, I ill. SP

The filling of the transport with liquid and gas (L1 contributes to the quenching) of the waste (J.Ie, and the torsional momeit) is transferred to the construction slightly.
