In the related art, after a strong earthquake occurs, the bottom of a shear wall member of a reinforced concrete frame-shear wall structure is often severely damaged due to the action of a huge overturning bending moment. Because the shear wall components are the main bearing components of the structure and are cast-in-place concrete components, the maintenance and replacement difficulties are great. The earthquake damage of the New Zealand Christian City in 2011 shows that the collapse probability of the frame-shear wall structure is usually very small, but once the bottom of the shear wall member is damaged, the maintenance cost is extremely high, and a large number of frame-shear wall structures in the New Zealand Christian City earthquake in 2011 are dismantled and reconstructed due to the over-high post-earthquake repair cost, so that huge economic loss is caused.
In order to solve the above problems, most of researches at present mainly provide energy dissipation devices at the corner of a concrete wall to reduce the damage of the concrete member. However, the above method weakens the shear load capacity of the component, potentially causing shear failure of the bottom section of the component. The bottom of the outer wall limb still has an irreplaceable concrete member, and the outer wall limb still has a larger possibility of damage under the action of strong vibration, thereby causing difficult maintenance.
Therefore, the invention provides the bottom-sectional assembly type shear wall structure 100 with the function of seismic recovery, which is convenient for rapid maintenance after seismic and is beneficial to reducing the maintenance cost.
A bottom-mounted seismic function recoverable shear wall structure 100 according to an embodiment of the invention is described below with reference to the accompanying drawings.

The adjacent steel columns 21 are detachably connected, so that the replaceable steel column assembly 2 is convenient to install and detach, and quick repair after earthquake is facilitated.
The second connecting profile steel member 3 is provided on top of the exchangeable steel column assembly 2. For example, in the example of fig. 1, the second connection section steel member 3 may be provided at the upper end of the replaceable steel column assembly 2, and the second connection section steel member 3 is connected to the replaceable steel column assembly 2.
The upper reinforced concrete wall body 4 is arranged on the second connecting steel structural member 3, the upper reinforced concrete wall body 4 is manufactured by adopting a cast-in-situ process, and the upper reinforced concrete wall body 4 and the plurality of steel columns 21 work cooperatively through the second connecting steel structural member 3 to resist the side effect of an earthquake.
Wherein, the replaceable steel column component 2 is constructed so that the bending resistance bearing capacity of the section is smaller than that of the section of the upper reinforced concrete wall 4, so as to ensure that the damage after earthquake is concentrated in the replaceable steel column component 2. Specifically, in the process of structurally designing the bottom-section-assembled seismic function-restorable shear wall structure 100, the steel columns 21 can adopt mild steel with proper strength, cross-sectional forms (such as an i shape, a box shape and the like) and cross-sectional dimensions, so that the bending-resistant bearing capacity of the replaceable steel column assembly 2 formed by the steel columns 21 is ensured to be smaller than that of the upper reinforced concrete wall body 4, and therefore damage after earthquake is ensured to be concentrated in the bottom-replaceable steel column assembly 2, and the upper concrete wall body 4 and the connecting profile steel members (including the first connecting profile steel member 1 and the second connecting profile steel member 3, and the following is not damaged). Repair can be completed by replacing the damaged steel column 21 after earthquake, so that the operation is easy, and the maintenance cost is reduced.
In the process of carrying out structural design on the replaceable steel column assembly 2, a sufficient number of bolts 5 are arranged among the plurality of steel columns 21, so that the integral shearing bearing capacity of the replaceable steel column assembly 2 is larger than the integral bending bearing capacity of the replaceable steel column assembly, and the replaceable steel column assembly 2 is ensured not to be subjected to poor-ductility shearing damage.
According to the bottom subsection assembly type seismic function restorable shear wall structure 100 provided by the embodiment of the invention, the bending resistance bearing capacity of the whole section of the replaceable steel column assembly 2 is smaller than that of the section of the upper reinforced concrete wall body 4, so that the damage after the earthquake is concentrated in the replaceable steel column assembly 2, the repair after the earthquake can be completed by replacing the damaged steel column 21, the operation is easy, and the maintenance cost is reduced.
According to some embodiments of the present invention, the replaceable steel column 21 is made of low-strength steel with good ductility, so that the bottom replaceable steel column assembly 2 is guaranteed to have good energy consumption performance, and brittle failure such as steel plate tearing can be avoided.

In other words, the replaceable steel column assembly 2 is connected to the first connecting section steel member 1 by bolts 5 (e.g., high strength bolts, etc.), and the replaceable steel column assembly 2 is connected to the second connecting section steel member 3 by bolts 5. Through adopting bolted connection, both guaranteed the reliability of connection, convenient structure's construction installation again and shake after repair replacement.
Further, screw holes (not shown in the figure) are preset at the interface of the first connection section steel member 1 and the replaceable steel column assembly 2 so as to enable the first connection section steel member 1 to be connected with the replaceable steel column assembly 2 through bolts; screw holes are preset at the interface of the second connecting steel member 3 and the replaceable steel column assembly 2 so as to enable the second connecting steel member 3 to be connected with the replaceable steel column assembly 2 through bolts. Thereby facilitating the mounting and dismounting between the first connecting profile steel member 1, the exchangeable steel column assembly 2 and the second connecting profile steel member 3.
The steel columns 21 are arranged in parallel, and the adjacent steel columns 21 are connected by bolts 5, so that a whole capable of bearing bending moment and shearing force is formed. The replaceable steel column assemblies 2 connected with the steel members and the bottoms are connected by bolts 5, and the replaceable steel column assemblies 2 are designed in a sectional assembly mode, so that the steel columns 21 juxtaposed at the bottoms can be replaced one by one while maintaining the vertical bearing capacity, and the function of the wall body after earthquake can be quickly recovered.
Referring to fig. 1 and 3, according to some embodiments of the present invention, a plurality of steel columns 21 are provided with first stiffeners 211, and the first stiffeners 211 may include a plurality of first stiffeners 211, and the first stiffeners 211 may be configured in a straight or T shape, or the like. The first stiffener 211 ensures that no local buckling of the plurality of steel columns 21 occurs.
Further, in conjunction with fig. 1 and 3, the first stiffener 211 may include: transverse stiffeners 2111 and longitudinal stiffeners 2112. The transverse stiffener 2111 extends in a horizontal direction (e.g., left-right direction as shown in fig. 1); the longitudinal stiffener 2112 is connected to the transverse stiffener 2111, and the longitudinal stiffener 2112 may extend in a vertical direction (e.g., up-down direction as shown in fig. 1). The first stiffening ribs 211 are beneficial to improving the rigidity of the replaceable steel column assembly 2 and ensuring that the plurality of steel columns 21 do not locally buckle.
According to some embodiments of the present invention, the first connection profile member 1 and/or the second connection profile member 3 are provided with a plurality of second stiffeners, each (or each) of which may be configured in a straight line (or T-shape, etc.). Therefore, a plurality of second stiffening ribs are arranged on the first connecting profile steel member 1 and/or the second connecting profile steel member 3, so that the connecting profile steel member is beneficial to ensuring that the connecting profile steel member is not damaged in earthquake such as yielding, local buckling and the like, and has larger rigidity and strength.

Therefore, the connecting profile steel member has larger rigidity and strength, and the damage of yielding, local buckling and the like in an earthquake is avoided.
According to some embodiments of the present invention, the upper reinforced concrete wall 4 is provided therein with longitudinal bars (not shown in the drawings) welded to the second connecting section steel member 3 in advance.

According to the bottom section assembly type earthquake-resistant function-restorable shear wall structure 100, under the action of the side force of an earthquake, the replaceable steel column assembly 2 is damaged and absorbs earthquake energy, so that the damage of the upper reinforced concrete wall body 4 is avoided. In the system, the connecting steel members are connected with the replaceable steel column assembly 2 by bolts 5, so that the integral bending rigidity and bearing capacity of the shear wall are ensured. Meanwhile, the adjacent replaceable steel columns 21 are connected by bolts 5, so that the shear rigidity and bearing capacity of the whole wall body are ensured.
