The invention discloses a test device for light steel frame beam column node bearing test. The device includes a device bottom plate assembled and fixed to a universal testing machine, a lower clamp groove provided with a light steel frame beam column, an upper clamp groove, fastening bolts for fixing the light steel frame beam column, an upper cover plate for fixing the light steel frame beam column, a bottom plate long groove for changing the loading point position, side plates connecting the bottom plate with the top plate, clamping plates for beam end loading, a hinge rod for loading an end, a beam column connection node test piece, and a mechanical universal testing machine. The whole test device can not only effectively realize the bearing performance test constraint condition of the beam column node, but also can measure the mechanical parameters of the beam column node test piece under the load by means of a strain gauge, a dial indicator, a displacement sensor, a force sensor or other tools while carrying out the loading, and therefore, the bearing mechanism and the mechanics model can be analyzed and studied. The whole device is clear in construction, convenient to use, and low in cost, and is a novel test device suitable for a miniature light steel beam column node test piece.
