Stand for testing of short-dynamic torsion static compression CONCRETE ELEMENTS

摘要

Stand for testing on the short-term dynamic torsional statically compressed concrete elements relates to the field of dynamic materials research. The technical result is to increase the reliability of information about the stress-strain state of a reinforced concrete element with respect to the predetermined duration of the power feedback. For the tests with achieving this result comprises a support stand for placing concrete element mounted on the power floor. On both ends of the reinforced concrete member installed additional support for placing traverse interconnected strands. At one end of the concrete element bearing and wearing tight end cap with the lever for a shock load is applied. The second end of the reinforced concrete element is rigidly clamped in a metal shoe, which rests on the yoke. Between the end cap and the corresponding traverse a hydraulic jack. The jack abuts the end cap through the metal gasket as a spherical segment. To implement power impact on the power floor mounted U-shaped frame. Racks U-shaped frame installed on both sides of the concrete element. On the lever end cap is a metal tube with a load, a second end of which is fixed on the crosspiece U-shaped frame. The load is formed of cylindrical shape and fitted onto the metal pipe with the possibility of moving and fixing. Base load is provided by rubber gaskets, thickness and the number which the predetermined duration of force action on the concrete element.1 N.C. 1 and ZP f-ly 1 Fig.
