6. The panel compression stability test apparatus of claim 5, wherein the side support struts in the side brace assemblies are in line contact with the test piece to provide a small amount of out-of-plane restraint to the test piece during compression.
7. The panel compression stability test apparatus of claim 1, wherein the adjustment rod assembly includes an adjustment rod, a shaft support and a sliding bushing disposed between the side support plate assemblies for providing lateral support; the adjusting rod is of a cylindrical rod structure, external threads are arranged at two ends of the adjusting rod, the shaft support is of a rectangular block structure and is provided with a through hole and a threaded hole, the sliding shaft sleeve comprises a sliding sleeve and a shaft which are of a cylindrical rod structure with a shoulder, and the sliding sleeve is provided with a through hole to form a sliding kinematic pair with the shaft.
8. The wallboard compression stability testing apparatus of claim 7, wherein the rib clamping assembly comprises a fixing clamp and a fixing band, the fixing clamp is of an open groove type structure, a threaded connection through hole is formed in the upper end face of the fixing clamp, the fixing band is an L-shaped angle bar or a return-shaped section bar, and the fixing band is installed in the open groove of the fixing clamp and used for limiting the out-of-plane displacement of the tested piece rib; the rib clamping assembly is arranged on the adjusting rod assembly in a matched mode.
9. The web compression stability test apparatus of claim 8, wherein the rib clamp assembly is configured to vary an out-of-plane support factor for the test piece rib by adjusting a contact pattern of the retention strap with the test piece rib, a number of the retention clips, and a clamp preload.
10. The panel compression stability test apparatus of claim 9, wherein the adjustment rod assembly is connected to the retaining clip in the rib gripping assembly by a shouldered shaft of the sliding bushing to effect a kinematic pair of the rib gripping assembly through the sliding bushing to release the test piece compression direction freedom.
