Description

Technical Field

[0001] The present invention relates to the field of architecture engineering, and particularly to a hybrid structure of a steel plate shear wall - wood frame that can be recovered after an earthquake and a construction method thereof.

Background Art

[0002] Wood structures have advantages such as being environmentally friendly, easy to assemble, and having high seismic resistance performance, so they are attracting more and more attention. However, conventional wood structures are often applied to low-rise buildings of 2 to 3 floors. At the current stage of high population density in China, it is difficult to meet the demand for land utilization rate. In order to make full use of the excellent performance of wood, it is necessary to urgently develop multi-high-rise wood structures and wood-concrete structure systems. However, in multi-high-rise wood structures, the lateral resistance performance is weak. According to the current seismic design code in China, the seismic countermeasure goals and design methods are respectively three-level countermeasures and two-stage design methods. Conventional pure wood structure systems resist seismic actions through the ductility of building materials and structural deformation, consume seismic energy, and ensure the safety of the main structure. Although the structure did not collapse after the earthquake, large residual deformations often occurred in the structure and components, increasing the difficulty and cost of repairing the structure after the earthquake. The steel-wood hybrid structure gives full play to the respective advantages of wood and steel, and its seismic resistance performance is greatly improved compared with pure wood structures. The steel-wood structure can develop into multi-high-rise and large-span structures. Furthermore, the degree of prefabrication of the steel-wood hybrid structure is high, which is in line with the concept of green buildings.

[0003] However, the recoverable functional characteristics in the seismic design of steel-wood hybrid seismic walls have not been well designed and realized. After an earthquake, large residual deformations occur in the steel frame and wood shear walls, making repair difficult. Patent CN105756217B provides a steel-wood hybrid seismic wall with self-recovery function after an earthquake. Using a friction damper, under a moderate or large earthquake, the shear force applied to the friction damper is greater than the slip shear force. The friction surface of the damper starts to slip and dissipates energy, which can significantly reduce the damage of the wood shear wall. The post-tensioning unbonded prestressed tendon is always in an elastic tension state. After an earthquake, the beam-column node returns to its initial state under the action of the prestressed tendon. The steel beam and steel column are basically not damaged, and the residual deformation of the structure is very small. The friction damper is not damaged by the earthquake action and does not need to be replaced after an earthquake. However, the friction damper only has an energy dissipation effect and does not have a self-recovery function, and the organic friction material in the friction damper may be damaged. The single horizontal bearing capacity of the seismic wall proposed in this patent is not high. When applied to a structural system, it may be necessary to arrange many such shear walls. The wood shear wall is prone to damage under the action of horizontal cyclic loading (Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present invention is to provide a hybrid structure of a steel plate shear wall - wood frame that can reduce the earthquake damage of a multi - high - rise wooden structure and can be recovered after an earthquake, and its construction method, in order to overcome the defects existing in the above - mentioned prior art and solve the problem that the lateral resistance performance of a multi - high - rise pure wooden structure is insufficient. The present invention can fully exert the characteristics of two types of materials. In terms of architecture, the structural system can rationally utilize the building space. In addition to the distribution of shear walls in the lateral resistance system, the building separation of the laminated timber frame system is flexible. In terms of structure, the structural system can fully exert the advantages of the lateral resistance capacity of the steel plate shear wall structure and the load - bearing capacity of the laminated timber frame structure. Through reasonable design, the functions of both the lateral resistance system and the load - bearing system are separated, and each plays its role. Furthermore, the dampers between the two systems deform when many earthquakes occur and consume the earthquake input energy. Under the action of the design seismic intensity earthquake and rare earthquakes, the lateral resistance system consumes energy to resist the earthquake action. In this way, by fully utilizing the hierarchy and arrangement form of different structural members in the structural system, a two - stage strengthened force - bearing characteristic and a mechanism that can recover the function after an earthquake are formed for the whole structure, and the cost and difficulty of repairing the structure after an earthquake can be reduced.

Advantages of the Invention

[0020] Compared with the prior art, the present invention has the following advantages. (1) The present invention introduces a steel plate shear wall into the wooden structure, greatly improving the lateral resistance performance of the structure. In the hybrid structure system of the steel plate shear wall - wooden frame, most of the lateral forces are borne by the steel plate shear wall, reducing the destruction of the wooden structure part. (2) The present invention has a high shock absorption effect and excellent seismic performance. Under small earthquakes, the steel plate shear wall has good lateral resistance rigidity and can resist horizontal seismic shear forces. Under medium or large earthquakes, the steel plate shear wall can bear most of the lateral forces. At the same time, the self - returning shear dampers between the steel plate shear wall and the glued laminated timber frame deform to fully play the role of energy consumption and shock absorption. (3) The present invention has a self - restoring function, with a structure that is easy to repair after an earthquake, significantly reducing the repair cost. Under a moderate earthquake or a major earthquake, the steel plates of the self - restoring shear damper consume energy through mutual friction, effectively controlling the deformation of the steel plate shear wall and significantly reducing the damage of the steel plate shear wall. The post - tensioned unbonded prestressed tendons on the edge beams of the steel plate shear wall are always in an elastic tension state. Under the action of the prestressed tendons, the structure returns to its initial state, and the residual deformation of the structure is very small. When the self - restoring shear damper maintains its elasticity under earthquake action without irreversible deformation or damage, it can withstand multiple earthquake actions. (4) The present invention adopts a large number of prefabricated members. Coupled with the ease of construction of the wooden structure itself, it greatly improves the construction speed and progress of the structure, conforms to the development trend of building industrialization, and has great prospects in actual engineering applications.
