AI Technical Summary
Existing cross-material in-plane stability bearing capacity testing devices are costly, have strict site requirements, are difficult to adapt to different specifications of main materials, and cannot simulate the complex stress state of cross-materials simultaneously bearing combined tensile and compressive loads in actual structures.
An experimental device was designed, comprising a self-balancing frame structure, a cross-staff main structure, an out-of-plane constraint system, and an in-plane loading system. Stress in the connecting components was eliminated by bolted connections, and adjustable out-of-plane constraints and double shear connections were used to achieve tension-compression proportional loading.
It enables testing on ordinary flat ground, reduces costs, adapts to different specifications of main materials, truly reflects the actual stress performance of the structure, and provides reliable test data.
