Description

The steel pipes do not directly bear external loads, but mainly constrain the core concrete. Steel pipe bound reinforced concrete columns have high bearing capacity, superior earthquake resistance and fire resistance, and can make full use of the strength of high-strength steel and concrete. When the steel pipe constraining the reinforced concrete member is circular, the steel pipe restrains the core concrete evenly, and the tensile strength of the steel pipe can be fully utilized, and the economic benefit is good. With the development of urban traffic, urban bridges have higher and higher requirements for piers. The use of hollow section columns can save materials and improve the bending and torsion resistance of bridge piers. This type of piers is widely used in urban bridges. At present, my country is gradually promoting the industrialization of construction. Industrialized buildings not only have the advantages of fast construction speed, high construction quality, and improved construction environment, but also meet the requirements of sustainable development. According to the characteristics of bridge construction, a prefabricated hollow steel tube confined reinforced concrete single-column pier is proposed.
