The invention discloses a small-size steel rack reaction wall which comprises a plurality of long support columns, horizontal platform surface bases, L-shaped short side bases and L-shaped long side bases, wherein the plurality of the long support columns are deeply buried under the ground and are used for supporting support; the horizontal platform surface bases are arranged at the tops of the plurality of the long support columns, take the shape of a rectangle and are used for providing mounting spaces; the L-shaped short side bases are fixedly mounted in short side positions of the horizontal platform surface bases, are positioned above the horizontal platform surface bases and are perpendicular to the horizontal platform surface bases; the L-shaped long side bases are fixedly mounted in long side positions of the horizontal platform surface bases, positioned above the horizontal platform surface bases and are respectively perpendicular to the horizontal platform surface bases and the L-shaped short side bases; and mounting positioning holes are formed in the L-shaped short side bases and the L-shaped long side bases and are used for providing mounting and loading positions. A structure test can be implemented on the small-size steel rack reaction wall disclosed by the invention like a conventional reaction wall, and the cost, the labor, the time, the material and the like are all greatly reduced on premise that structural damage mechanisms are needed.
Description
technical field [0001] The invention belongs to the field of anti-seismic tests of civil engineering structures, in particular, the invention relates to a small steel frame reaction wall. Background technique [0002] In the field of seismic testing of civil engineering structures, large-scale reaction walls must be used as supports when large-scale building models or full-scale component seismic performance tests need to be completed. The reaction wall is a pseudo-dynamic test facility. Two mutually perpendicular reaction walls can carry out two-dimensional pseudo-dynamic test research on structures and components. The reaction wall itself must have sufficient rigidity and strength. During the structural seismic test, the reaction wall will be subjected to the reverse force, so it is required that the reaction wall should not have inclined cracks. Generally speaking, the reaction wall is a shear wall structure with sufficient rigidity and strength. In order to realize the...
