Abstract

The invention relates to a steel-continuous fiber composite rib enhancing concrete antiseismic construction that adopts steel-continuous fiber composite rib with normal reinforcing bar as main rib. The steel-continuous fiber composite rib adopts intermix FRP that covering layer covers the inner core of reinforcing bar. The column, node and frame of antiseismic construction are made up of the column, node, frame identity, steel-continuous fiber composite rib and stirrup. The composite rib is located in the concrete structure protection layer, and was encircled by stirrups, and framework is formed between them by the method of lashing or sintering. After the steel-continuous fiber composite rib preprocessed, taking cementing control process to the external surface of the mixing FRP covering layer of steel-continuous fiber composite rib, and pouring into the concrete structure identity.

Description

technical field

[0001] The invention relates to the application of a steel-continuous fiber composite bar (SFCB) and its reinforced concrete anti-seismic structure in civil engineering and traffic engineering, and belongs to the technical field of new material structures. Background technique

[0002] At present, my country's current seismic code adopts the method of "three-level fortification and two-stage design". Among the three levels, "not damaged by small earthquakes" and "not collapsed by major earthquakes" have quantified parameters, which are convenient for application in actual design. But for "moderate earthquake repairable", the code only gives a qualitative description, and it is only guaranteed by structural measures, so it is difficult to be reflected in the actual design, and "moderate earthquake repairable" cannot be truly realized. Secondly, with the development of materials and earthquake engineering technology, the transformation of the fortification thi...
