[0001] The invention belongs to the technical field of seismic treatment of shear walls, in particular to a seismic reinforcement method of shear walls based on the energy dissipation principle. Background Art
[0002] In areas where earthquakes occur frequently, shear walls are important lateral force-resisting components in building structures, and their seismic performance is directly related to the safety of buildings. Traditional shear wall seismic reinforcement methods are mainly achieved by improving the strength and stiffness of the structure itself. Although these methods enhance the seismic resistance of the structure to a certain extent, they often have disadvantages such as high cost, long construction time, and narrow scope of application. Moreover, the structures reinforced by traditional reinforcement methods do not have self-regulation capabilities and are difficult to adapt to the unpredictability of earthquakes and the complexity of structural responses.
[0003] In recent years, seismic design methods based on the principle of energy dissipation have gradually gained attention. This method introduces energy dissipation devices to convert seismic energy into heat or other forms of energy for dissipation, thereby reducing the damage caused by earthquakes to structures. However, in the field of seismic reinforcement of shear walls, how to effectively apply the principle of energy dissipation to achieve an economical and efficient seismic reinforcement effect is still a problem that needs to be solved.
[0004] To this end, those skilled in the art have proposed a shear wall seismic reinforcement method based on the energy dissipation principle to solve the problems raised by the background technology. Summary of the invention

[0022] Figure 1 The present invention is a flow chart of the method for seismic reinforcement of shear walls based on the energy dissipation principle. DETAILED DESCRIPTION
[0023] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0024] Embodiment: The present invention provides a method for seismic reinforcement of shear walls based on the energy dissipation principle, such as Figure 1 As shown, including:
[0025] S1. Installing an energy dissipation device at a predetermined position of the shear wall, the energy dissipation device comprising a damper, a shear wall connector and a fixed structure, the damper being used to convert seismic energy into heat energy or other forms of energy to dissipate seismic energy;
[0026] S2. adjusting the installation position, quantity and parameters of the energy dissipation device to achieve the optimal energy dissipation effect according to the seismic requirements of the shear wall;
[0027] S3. The damper is firmly connected to the shear wall through connectors, and it is ensured that the connectors can withstand the load under earthquake action without affecting the normal use function of the shear wall.
[0028] From the above, it can be seen that by introducing energy dissipation devices such as dampers and cleverly installing them at the predetermined positions of the shear walls, effective conversion and dissipation of earthquake energy is achieved. This method not only enhances the seismic performance of the shear walls and reduces the damage caused by earthquakes to the building structure, but also can achieve the optimal energy dissipation effect according to specific seismic requirements by flexibly adjusting the installation position, number and parameters of the energy dissipation devices. In addition, the additional steel plates and their yield energy dissipation algorithms further enhance the scientificity and accuracy of seismic reinforcement, making this method both economical and efficient and easy to implement, bringing new solutions to the field of shear wall seismic reinforcement.
[0029] Furthermore, the damper is any one or more combinations of a liquid damper, a pendulum damper or a friction damper.
[0030] Furthermore, the damper is used to convert seismic energy into heat energy or other forms of energy to dissipate seismic energy. By introducing a damper to convert seismic energy into heat energy or other forms of energy to dissipate seismic energy, it includes: assuming that the total energy of the seismic input is E s , the energy dissipated by the damper is E h , then the formula for energy dissipation efficiency includes:
[0031] η=E h / E s ;
[0032] Among them, η represents the energy dissipation efficiency, which is a value between 0 and 1.
[0033] From the above, it can be seen that by adopting various types of dampers such as liquid dampers, pendulum dampers or friction dampers, and converting seismic energy into heat energy or other forms of energy for dissipation, the flexibility and adaptability of shear wall seismic reinforcement are greatly improved. This design not only makes the energy dissipation process more efficient, but also can quantitatively evaluate the energy dissipation effect of the damper by introducing the formula of energy dissipation efficiency, providing a scientific basis for seismic reinforcement design and optimization. It not only enhances the seismic performance of shear walls, but also provides new ideas and methods for seismic reinforcement strategies in engineering practice.
[0034] Furthermore, it also includes adding a steel plate at the bottom of the shear wall or a part susceptible to earthquake damage, wherein a plurality of through holes are arranged on the steel plate to further dissipate the earthquake energy through the yielding and deformation of the steel plate under the action of the earthquake. At the same time, in order to quantify the energy dissipation effect of the steel plate, a yielding energy dissipation algorithm of the steel plate is introduced, and the yielding energy dissipation algorithm includes:
[0035] E p =σ m *δ m *A;
[0036] Among them, σ m Indicates the yield strength of the steel plate, δ m represents the yield strength of the steel plate, and A represents the area of the steel plate.
[0037] As can be seen from the above, the present invention adds a steel plate with through holes at the bottom of the shear wall or at a location susceptible to earthquake damage, further dissipating earthquake energy through the yielding and deformation of the steel plate, significantly enhancing the seismic performance of the shear wall. At the same time, in order to scientifically quantify the energy dissipation effect of the steel plate, the present invention introduces a yielding energy dissipation algorithm for the steel plate, which can accurately calculate the energy dissipation capacity of the steel plate, providing a powerful tool for the evaluation and optimization of the seismic reinforcement effect. It not only improves the seismic safety of the shear wall, but also provides important support for the refined design and implementation of seismic reinforcement methods.
[0038] Furthermore, the number, arrangement and size of the through holes of the steel plate are customized according to earthquake resistance requirements to ensure that the steel plate yields and dissipates energy first under the action of an earthquake.
[0039] As can be seen from the above, the number, arrangement and size of the through holes of the steel plate of the present invention are customized according to the seismic requirements. This refined adjustment ensures that the steel plate can yield preferentially and effectively dissipate energy under the action of an earthquake. This customized design not only improves the scientificity and pertinence of the energy dissipation of the steel plate, but also further optimizes the seismic performance of the shear wall, making the entire seismic reinforcement system more efficient and reliable. By precisely controlling the yield sequence and energy dissipation capacity of the steel plate, the present invention provides a more sophisticated and effective solution for the seismic reinforcement of the shear wall.
[0040] Furthermore, the effects of a shear wall seismic reinforcement method based on the energy dissipation principle of the embodiment and the conventional shear wall seismic reinforcement method (comparative example) are compared to obtain the following table:
