METHOD OF TESTING ASEISMIC BUILDING CORNERS AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1998 - IPC

FIELD: civil engineering. SUBSTANCE: problem to be solved herein is determination of interaction of walls and building corners with foundation and determination of seismic stability coefficients of materials. Formation of jointly imposed loads and superposition of couplings made it possible to determine effect of walls exerted on foundation. Horizontally-pulsating loads along walls are created separately by force exciters with frequency periods of 5, 11, 17 Hz. Vertical vibrations were produced by means of table vibrator. Seismic stability coefficients of materials $$$ and deformation $$$ are obtained for limiting and destruction stages. In presence of damper installed between walls and their foundations values $$$ turned to be 3-4 times below the values obtained when damper was not used. EFFECT: higher test results. 4 cl, 3 dwg, 1 tbl
