Prestressed fibre reinforced steel concrete structure and its prestressed construction method

Abstract

The present invention relates to prestressed fibre-reinforced section steel concrete structure and its prestressing construction method. The present invention is mainly composed of fibre cloth, section steel and concrete. The invented prestressed fibre-reinforced section steel concrete structure possesses the advantages of light-weight, high rigidity, bearing capacity of heavy load, very large spanning ability, etc. Its construction method is simple, and the formed engineering structure performance is excellent.

Description

1. Technical field [0001] The invention belongs to civil engineering structures and construction methods thereof, in particular to engineering structures with special requirements and construction methods thereof. 2. Background technology [0002] At present, in the field of civil engineering, the commonly used reinforced concrete and steel concrete structures have the disadvantages of heavy weight and small spanning ability. And because concrete is a material with good compressive performance but poor tensile performance (generally 2-5MPa), it is easy to crack and damage. In addition, with the continuous development of society, people have put forward new requirements for civil engineering, such as light structure, wide space, large bearing capacity, etc., so it is difficult to adopt ordinary reinforced concrete structures and steel concrete structures. Meet the needs of modern large-scale civil engineering. Moreover, for steel concrete structures, the plastic properties ...

AI Technical Summary

Problems solved by technology

[0002] At present, in the field of civil engineering, the commonly used reinforced concrete and steel concrete structures have the disadvantages of heavy weight and small spanning capacity.

And because concrete is a kind of material with good compressive performance but poor tensile performance (generally 2-5MPa), it is easy to crack and damage

In addition, with the continuous development of society, people have put forward new requirements for civil engineering, such as light structure, wide space, large bearing capacity, etc., so it is difficult to adopt ordinary reinforced concrete structures and steel concrete structures. Meet the needs of modern large-scale civil engineering

Moreover, for steel concrete structures, the plastic properties of steel have not been fully utilized when designing according to the allowable stress method.
