为适应高层建筑、立交桥和港口等建筑物对防震、抗震及增加结构稳定性等要求，国外已开发研制出内螺旋凸筋焊管，用作高层建筑的地基柱和立交桥的立柱等。内螺旋凸筋焊管在建筑构件中的使用，可以增强钢管与混凝土之间的结合力，增加二者之间的应力传递，提高钢管混凝土结构的 To meet the high-rise buildings, overpasses and ports and other buildings on the earthquake, seismic and increase the stability of the structure and other requirements, has developed a foreign spiral welded pipe, used as a high-rise building foundation column and overpass columns. The use of internal helical ribbed welded pipe in building components can enhance the binding force between steel pipe and concrete, increase the stress transfer between the two and increase the strength of CFST structure
