Abstract

The invention discloses an FRP (fiber reinforced plastic)-steel composite tube concrete column and relates to a civil engineering structural element, the composite tube concrete column consists of an FRP-steel composite tube and concrete filled therein and is characterized in that the FRP-steel composite tube is formed by compounding a steel tube as an inner wall with an FRP tube as an outer wall, the steel tube is formed by welding a steel plate, the FRP tube is prepared by winding continuous fiber yarn on the outer surface of the steel tube, and the solid concrete is poured in the composite tube. The FRP-steel composite tube concrete column can fully play the respective advantages of three composition materials of FRP, steel and concrete and has the characteristics of high bearing capacity, corrosion resistance, excellent aseismic performance and the like, thereby providing a new choice for civil engineering construction.

Description

A kind of FRP-steel pipe concrete column
Technical field
The invention belongs to a kind of civil engineering structure member, be particularly related to a kind of coupled column of forming by FRP pipe, steel pipe and three kinds of different materials of concrete, be particularly useful for highrise building, bridge engineering, underground construction and port works etc. under the adverse circumstances such as ocean, humidity and salt-soda soil.
Background technology
At present, the concrete filled steel tube rod structure is widely used in highrise building, bridge engineering, underground construction and port works etc. in China, and has obtained great economic and social benefit.High-strength concrete can be described as the most perfect combination with the steel pipe pressure-bearing, can be rated as to give full play to the model of characteristic separately, has excellent ductility feature simultaneously.Yet when the suffered load of steel core concrete column was big, member section still can be bigger, and need the thicker steel pipe of wall thickness to offer the enough clamping forces of concrete this moment.Therefore, steel using amount is still bigger than normal, and the supply channel of major diameter, thick walled steel tube is few, if adopt double-layer pipe, then difficulty of construction is bigger, if adopt high strength steel pipe, then cost is higher.In addition, in adverse circumstances such as ocean, humidity and salt-soda soil, use encased structures, its outer steel pipe need be brushed anticorrosive paint or adopt special anticorrosive measure, has so greatly increased construction costs and technical difficulty, and the expense of later maintenance simultaneously is also than higher.
Because fibre reinforced plastics (FRP) material has very high tensile strength, concrete filled can play the effect same with concrete filled steel tube in the FRP pipe, especially the FRP material has characteristics such as lightweight, corrosion-resistant and designability be strong, in civil engineering, obtained increasing concern in the last few years, the appear as bridge pier, pile foundation, the isostructural endurance issues of the overhead sign of highway of FRP pipe concrete column have proposed effective solution, and it is with a wide range of applications in field of civil engineering.Yet, the FRP material is the linear elasticity material, though can suitably improve its failure mode by optimizing ply sequence, make the FRP pipe concrete column show to a certain degree ductile fracture, the ductility degree that it obtained still can't satisfy the more and more higher requirement to structural seismic performance.Simultaneously, the axial rigidity of FRP pipe is lower, may be in the process of concreting owing to concrete deadweight produce cripling, and cause lateral deflection excessive and form cripling and destroy.
Summary of the invention
In order to overcome the above-mentioned shortcoming and defect of existing steel core concrete column and FRP pipe concrete column, carry out steel pipe and FRP pipe compound, a kind of newly-built structure that can be used for is provided, the FRP-steel pipe concrete column structure of highrise building, bridge engineering, underground construction and port works etc. under the adverse circumstances such as particularly suitable Yu Haiyang, humidity and salt-soda soil, one side can improve the stress performance and the anti-seismic performance of structure; In adverse circumstances such as ocean, humidity and salt-soda soil, have advantages such as favorable durability on the other hand.
The present invention is achieved through the following technical solutions:
FRP-steel pipe concrete column, form by FRP-steel pipe and the concrete that pours into wherein, the FRP-steel pipe is by being composited as the steel pipe of inwall with as the FRP pipe of outer wall, steel pipe is welded by steel plate, the FRP pipe is twined on outer surface of steel tube by the continuous fiber yarn to be made, and builds solid concrete in the clad pipe.
Described FRP-steel pipe is pipe, square tube or rectangular tube.
Described concrete is ordinary concrete or high-strength concrete.
Described FRP is a kind of in glass fiber reinforced plastics, carbon fibre reinforced plastic, basalt fibre reinforced plastic, aromatic polyamide fiber reinforced plastics or the four kinds of fiber hybrid reinforced plastic.
The present invention has the following advantages and effect with respect to prior art:
1. the present invention is the coupled column that is made of FRP pipe, steel pipe and three kinds of different materials of concrete, can give full play to constituent material characteristic separately: the supporting capacity of concrete under three axial compression stress states; The FRP pipe is to steel pipe and the lasting hoop effect of contraction of core concrete; The elastoplasticity of steel pipe makes structure have good axial compression ductility;
2.FRP the outsourcing of pipe constraint not only can reduce the steel using amount of steel pipe, can also suppress the cripling that steel pipe produces in the axial compression process, can be used as the topping of steel pipe simultaneously again, improves the durability of structures energy;
3. steel pipe can be used as the winding mould in the winding process of FRP pipe, has saved the manufacturing cost and the knockout course of mould, has reduced cost of production;
4.FRP-steel pipe has bigger axial rigidity, make structure before concreting, have certain axial carrying capacity, template in the time of can be directly as concrete pouring is used, saved the manufacturing cost of template, shortened the construction period, can also avoid the cripling phenomenon to occur in the concreting process simultaneously.
