Multi-directional application of steel pipe in structure

What are the structural applications of steel tubes? Structural steel pipe, including a variety of welded pipe and seamless pipe, because of the ideal annular cross-section, so that the ability to resist local buckling is very strong, is subjected to radial internal pressure and external pressure of the best lightweight components. The basic components, such as column and beam, can be used for structure alone, and can be combined into frame, diffraction frame, net frame and other structure types.

In steel and concrete composite structures, the concrete filled steel tubular columns which are being popularized are the new field of effective steel pipe application. For the grid structure is very popular. The grid structure of the hollow spherical joint or the bolt-ball node has been in vogue for a long time, and the steel pipe is the best choice. High-rise structure is also very common, steel pipe not only superior cross-section performance, the external surface of the arc can significantly reduce the role of wind load. The use of steel-tube masts or mast towers can give full play to these advantages.
