AI Technical Summary

Technical Problem

Traditional loading racks and large multi-functional loading systems struggle to balance flexibility, low cost, and adaptability, failing to meet the lightweight testing needs of small and medium-sized laboratories for various bolted connections and components.

Method used

A modular multifunctional loading frame is designed, comprising a bottom beam and a top beam arranged in a straight line. The modular combination is achieved through axial screws and jacks, enabling flexible application of axial force and vertical load. It is suitable for mechanical property testing of bolted hollow steel pipes, steel-concrete composite pipes, bolted T-shaped parts, and bolt groups.

Benefits of technology

It reduces research funding costs, shortens the experimental cycle, improves research efficiency, is suitable for the budget and space resources of small and medium-sized laboratories, covers the mainstream needs of steel structure node research, and ensures the accuracy and reliability of experimental data.
