VIBRATION STAND FOR TESTING BUILDING CONSTRUCTIONS FOR SEISMIC LOAD Russian patent published in 2018 - IPC G01M7/04 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to test stands for testing building structures, models, fragments of buildings and structures, as well as self-supporting and non-load bearing elements and equipment in their composition in the form of walls, floors, suspended facades, engineering systems and other equipment for dynamic effects characteristic of natural, natural and man-made or man-made nature, including earthquakes, wind loads and loads from moving vehicles. Claimed vibration stand for testing building structures for seismic loading includes a frame-mounted system of interconnected pillars and girders, a floor, a source of vibration of inertial action rigidly fixed on it and brackets for fastening of simulated test samples, while the frame system is made in the form of lower and upper rigid metal frames, connected among themselves by vertical struts through damping rubber gaskets, the lower frame around the perimeter is rigidly mounted on the base, and the floor consists of mounted on the upper frame of transverse H-beams and removable plates attached to them, made with through holes, providing an independent attachment of the vibration source on one of the slabs with the possibility of applying a dynamic load in two horizontal mutually orthogonal directions, and modeling brackets for the test samples.

EFFECT: technical result consists in increasing reliability and simplifying operation and repair.
