Abstract

The invention discloses a civil engineering structure explosion damage experiment platform, which comprises a base plate, a plurality of pillars and a plurality of cross bars welded on the corresponding pillars, the middle part of the base plate is provided with a locking device for fixing a test piece, the Both sides of the locking device are symmetrically provided with a first test device and a second test device for testing explosion parameters, and a plurality of cross bars are jointly provided with fixing devices for fixing explosives. There are two protective plates at both ends of the base plate, each of which is slidably provided with a plurality of screws. The invention has a novel structure, and can detect explosion pressure parameters in various directions around the test piece. When the shock wave generated by the explosion propagates around, the first test board and the second test board can not only rely on their own strength to resist the impact force, but also The kinetic energy of the shock wave can be converted into the kinetic energy and internal energy of multiple devices to avoid damage to the experimental platform.

Description

Technical field [0001] Technical Field The present invention relates to civil engineering, particularly to a civil engineering structure explosion experiment platform damage. Background technique [0002] Explosion is an interdisciplinary between fluid mechanics, solid mechanics and physics, chemistry, has been widely used in weapons development, transportation, water conservancy construction, civil engineering and other aspects, the explosion damaged the experiment is to explore the object or structure in short change or features of structural damage and the extent of damage in the mechanical properties of partial excitation shockwave time, civil engineering because of their specificity, as compared to ordinary chemicals explosion test, civil engineering explosion experiments generally only considered explosion unconstrained ground to the power load member when the response of steel concrete column member, and therefore, the structure for civil engineering explosive damage exper...
