With the development of science and technology, the application of steel structure in building engineering is more and more widely. The hot-rolled section steel is welded, bolted, or riveted together to form the basic components according to certain rules, irregularly welded, bolted, or rivet joints are used to connect the basic members into structures capable of withstanding external loads as steel structures. High Strength, small quality, good plasticity and toughness, poor corrosion resistance, and other advantages.
