Low-cycle reciprocating test device for concrete member

Abstract

The invention discloses a low-cycle reciprocating test device for a concrete member. The device comprises a concrete test piece, a clamp and bases, wherein the bases are cushioned under the two ends of the concrete test piece, rigid supports are arranged on the two sides of the bases, a distribution beam is arranged in the middle of the concrete test piece, a lower steel sheet is arranged under the middle of the concrete test piece, the distribution beam is connected with the lower steel sheet through second screw rods, and first anchorage devices are arranged among the distribution beam, theconcrete test piece and the lower steel sheet. The low-cycle reciprocating test device disclosed by the invention has the advantages that the low-cycle reciprocating test device for the concrete member is more convenient to use and requires no complicated operation; in the loading process, the clamp and the distribution beam as a partial whole are connected with an upper structure, and the bases and the rigid supports as a partial whole are connected with a ground anchor, so that the stability outside of the plane of the concrete test piece is maintained, the lateral turnover is avoided, and the test safety is improved.

Description

technical field [0001] The invention relates to the research on the anti-seismic performance of beams applied in a laboratory, and belongs to the field of civil engineering, in particular to a low-cycle reciprocating test device for concrete components. Background technique [0002] Reinforced concrete structures and prestressed concrete structures are usually mainly subjected to static loads, but in actual engineering there are many structures, such as bridges or crane beams, which, in addition to bearing static loads, also bear repeated cyclic loads. With these With the increasing application of structures, many structures work under high stress conditions, which makes the fatigue of concrete structures a non-negligible problem. Contents of the invention [0003] The object of the present invention is to provide a low-cycle reciprocating test device for concrete components, which enables our concrete specimens to be combined with the loading device to complete the low-cy...
