HIGH-RISE MANY-STORIED ANTISEISMIC BUILDING Russian patent published in 1997 - IPC

FIELD: civil engineering. SUBSTANCE: in addition to construction of antiseismic buildings, proposed solution can be used in reducing oscillation of buildings under action of industrial and transport vibration and wind loads. Problem is solved by widening range of possible dynamic displacements and enhanced attenuation. Antiseismic building has many-storied spacious sections with flexible frameworks and deformation joints arranged between them in height. Spacious sections are interconnected to each other in height at level of interstory floors by pivoted links. Building is formed of at least three spacious sections located in plan along mutually perpendicular axes. Arranged in clearances between spacious sections are deformation joints which are filled in height with loose hydrophobic fractionated material produced from solid rock. Arranged along sides of deformation joint and over contours of technological openings is joint in the form of similar height ribs with flanges symmetrically located against each other. Width of flanges is determined from condition that it is larger than possible relative horizontal displacements of adjacent spacious sections, that is to meet this condition: b > a_x, where b - width of flange, a_x - possible relative dynamic displacement of adjacent spacious sections relative to each other at maximal seismic activity. Clearance between flanges of adjacent ribs must not exceed 1/3 of size of particles in fractionated loose material. EFFECT: high efficiency. 1 cl, 4 dwg
