Background
The pier column in the reinforced concrete structure is a typical anti-seismic component, the traditional pier column is mainly anti-seismic through a measure of hoop reinforcement, and the typical characteristic of pier column anti-seismic is that shear damage caused by seismic force is resisted through the reinforcement of the hoop reinforcement, so that operation is not easy, and the construction cost is higher. In addition, when the building structure or member is exposed to a corrosive environment for a long time, the building structure or member is continuously corroded with the passage of time, and the durability and the bearing capacity of the building structure or member are gradually degraded, so that the service life of the building structure is sharply reduced. If an earthquake occurs again, the frost is added on the snow to the building structure, so that casualties, economic losses and traffic paralysis are likely to be caused, and the earthquake-resistant building structure not only brings great disasters to local residents, but also brings great economic pressure to governments. The method is also an important reason for urgently solving the corrosion prevention and earthquake resistance of the pier column.
The invention can be used for the structural design of the anti-seismic and anti-corrosion pier stud in severe environment and other applicable building structures or component designs.
