The ability of reinforced concrete structure resistance consecutive shock disaster effect high turns into problem demanding prompt solution.
The content of the invention
The technical problem to be solved in the present invention is the drawbacks described above for how overcoming prior art, there is provided one kind improves reinforcing bar and mixes
The method that Xtah Crude Clay structure resists consecutive shock disaster.The method causes that existing reinforced concrete structure is protected under consecutive shock effect
Hold good anti-seismic performance.
In order to solve the above technical problems, the present invention is a kind of to improve the side that reinforced concrete structure resists consecutive shock disaster
Method, comprises the following steps:
A, making SMA " plastic hinge " connector, connect SMA connecting rods, by not between reinforcing bar and SMA connecting rods between two sections of reinforcing bars
Rust steel bushing head and the tail are connected, and stainless steel sleeve is connected with bar connecting one end using taper thread, and stainless steel sleeve connects with SMA connecting rods
One end is connect to be fixedly connected using bolt presses;
B, the areas of plasticity hinge that SMA " plastic hinge " connector is positioned over reinforced concrete structure, areas of plasticity hinge pass through structure
Seismic Calculation determines;
C, fixed SMA " plastic hinge " connector, then casting concrete, is built into the reinforcing bar for being embedded with SMA " plastic hinge " connector
Concrete structure.
Used as optimization, the cross section of the stainless steel sleeve is cylindrical, and one end is provided with carries out taper thread machinery with reinforcing bar
The cone cylinder shape groove of connection, the other end is provided with carries out the cylinder shape groove that bolt presses are fixedly connected with SMA connecting rods, connection
Longitudinally arranged zigzag guide rail in the cylinder shape groove of the stainless steel socket end of SMA connecting rods, connects the stainless steel sleeve of SMA connecting rods
The cylindrical hole slot inwall at cylinder end is provided with the zigzag guide rail groove matched with the zigzag guide rail.
Used as optimization, the zigzag guide rail is evenly arranged three along longitudinal direction, be respectively arranged in cylindrical hole slot inwall by
In the zigzag guide rail groove of 120 grades point processing.
Used as optimization, the reinforced concrete structure is multilayer multiple bay frame structure, unilayer moltispan frame structure or FRP muscle
Concrete structure.
The beneficial effects of the invention are as follows:
The present invention is directed to reinforced concrete structure, places SMA " plastic hinge " connector in its areas of plasticity hinge so that structure can
Generation large deformation is not destroyed, while recovering deformation after geological process terminates, small residual deformation is only existed, so as to improve steel
Anti-seismic performance of the tendon concrete structure under consecutive shock disaster.Reinforced concrete member is overcome to resist consecutive shock disaster ability
Poor defect;In addition, do not change the appearance and size of concrete, and convenient, economically feasible of constructing, it is that one kind effectively improves reinforcing bar
The method that concrete structure resists consecutive shock disaster ability.With preferable actual application value and promotional value.
Brief description of the drawings
Further is made to a kind of this method for improving reinforced concrete structure resistance consecutive shock disaster below in conjunction with the accompanying drawings
Explanation:
Fig. 1 is the structural representation of SMA " plastic hinge " connectors that the present invention is used and reinforcing bar combined method;
Fig. 2 is the structural representation of 1-1 sections in Fig. 1;
Fig. 3 be three layer one of one embodiment of the invention across reinforced concrete frame structure schematic diagram.
In figure:1 is reinforcing bar, 2 is stainless steel sleeve, 3 is bolt, 4 is SMA connecting rods, 5 is zigzag guide rail, A is for SMA " is moulded
Property hinge " connector, B be reinforced concrete structure, C be areas of plasticity hinge.
Specific embodiment
To make the objects, technical solutions and advantages of the present invention become more apparent, develop simultaneously embodiment referring to the drawings, right
The present invention is further described.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of this method for improving reinforced concrete structure resistance consecutive shock disaster, including with
Lower step:
A, quantity and diameter according to reinforced concrete structure B and required reinforcing bar 1, the SMA " plasticity needed for making the present embodiment
Hinge " connector A, connects SMA connecting rods 4 between two sections of reinforcing bars 1, by the head and the tail of stainless steel sleeve 2 between reinforcing bar 1 and SMA connecting rods 4
Connection, stainless steel sleeve 2 is connected one end with reinforcing bar 1 and is connected using taper thread, and stainless steel sleeve 2 is connected one end and adopts with SMA connecting rods 4
Connection is fixed with bolt 3;
B, the plasticity that the combination muscle that SMA " plastic hinge " connector A are connected formation with reinforcing bar 1 is positioned over reinforced concrete structure B
Hinge region C, areas of plasticity hinge C are determined by structural anti-seismic capacity;
C, fixed SMA " plastic hinge " connector A are connected the combination muscle for being formed with reinforcing bar 1, and then casting concrete, is built into and is embedded with
The reinforced concrete structure B of SMA " plastic hinge " connectors A.
Be so designed that, by reinforced concrete structure plastic hinge region set SMA " plastic hinge " connector, formed reinforcing bar-
The combination muscle of SMA- reinforcing bars.SMA connecting rods are introduced in reinforced concrete structure, the anti-seismic performance of structure is not only increased, and
