Problems solved by technology

[0003] In order to make the research on the mechanical performance of space frame beam-column joints more realistic, so that it can truly reflect the spatial combination effect of earthquake action on space frame beam-column joints, overcome the problem of using planar frame beam-column joints in a single direction (in-plane) The influence of loads in other directions (out-of-plane) on the actual performance of beam-column joints is not considered during loading. It is necessary to invent a performance test device for beam-column joints that can apply loads along the two main axis directions of the beam-column or the axial direction of the column.

Abstract

The invention discloses a loading device and a loading-device-based seismic test system for a beam-column joint. The loading device comprises an X-shaped base, four reaction frame square steel tube columns, four first reaction frame beams, four second reaction frame beams, four third reaction frame beams, four first reaction frame short oblique beams, four second reaction frame short oblique beams and two first steel beams. The seismic test system for the beam-column joint of a space frame comprises a first jack, four second jacks and the self-balancing reaction frame loading device. According to the device and the system, a seismic test in the beam-column joint of the space frame can be implemented.

Description

technical field [0001] The invention relates to the field of seismic performance testing, and relates to a loading device and a beam-column node seismic testing system based on the loading device. Background technique [0002] Generally, the research on the mechanical performance of space frame beam-column joints is mainly carried out with the plane horizontal unidirectional loading system, which is only applicable to plane beam-column joints. The test devices are mainly divided into two types: column end loading and beam end loading. Both the column end and the beam end are generally in the form of one-way hinges, resulting in only in-plane deformation of the column, but no out-of-plane deformation. Only bending deformation around its own axis can occur but not torsional deformation. [0003] In order to make the research on the mechanical performance of space frame beam-column joints more realistic, so that it can truly reflect the spatial combination effect of earthquake...
