Abstract
Description
Technical Field
[0001] This invention relates to the field of building engineering, and in particular to a post-earthquake recoverable steel plate shear wall-wood frame hybrid structure and its construction method. Background Technology
[0002] Timber structures are gaining increasing attention due to their advantages such as being environmentally friendly, easy to assemble, and having good seismic performance. However, traditional timber structures are mostly suitable for low-rise buildings of 2-3 stories, making it difficult to meet the current land utilization needs of my country's high population density. To fully utilize the excellent properties of timber, there is an urgent need to develop multi-story timber structures and timber-concrete structures. However, lateral resistance is a weak point in multi-story timber structures. Current seismic codes in my country use a three-level fortification target and a two-stage design method. Traditional pure timber structures resist earthquakes and dissipate seismic energy through the ductility of building materials and structural deformation, ensuring the safety of the main structure. Although the structure may not collapse after an earthquake, it often results in significant residual deformation of the structure and components, increasing the difficulty and cost of post-earthquake maintenance. Steel-timber hybrid structures fully utilize the advantages of both timber and steel, offering significantly improved seismic performance compared to pure timber structures. This allows steel-timber structures to be developed for multi-story and large-span structures. Furthermore, steel-timber hybrid structures have a high degree of prefabrication, aligning with green building initiatives.
[0003] However, the recoverable functional characteristics of steel-wood hybrid shear walls in seismic design have not been well designed and realized. After an earthquake, the steel frame and timber shear wall exhibit significant residual deformation, making repair difficult. Authorized patent CN105756217B provides a steel-wood hybrid shear wall with post-earthquake self-resetting function, employing friction dampers. Under moderate or severe earthquakes, the shear force on the friction damper exceeds its slip shear force, causing the friction surfaces in the damper to slip and dissipate energy, significantly reducing damage to the timber shear wall. The post-tensioned unbonded prestressing tendons remain in an elastic tension state. After the earthquake, the beam-column joints return to their initial state under the action of the prestressing tendons, with minimal damage to the steel beams and columns, minimal residual structural deformation, and the friction dampers do not fail under seismic action, requiring no replacement after the earthquake. However, friction dampers only dissipate energy and lack self-resetting functionality; the organic friction material within the damper may also be damaged. The shear wall proposed in this patent has a low single horizontal bearing capacity. When applied in a structural system, it may be necessary to arrange many such shear walls, and the wooden shear wall is prone to damage under horizontal cyclic loads. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by providing a post-earthquake recoverable steel plate shear wall-timber frame hybrid structure and its construction method to reduce earthquake damage in multi-story and high-rise timber structures, thereby addressing the problem of insufficient lateral resistance in multi-story and high-rise pure timber structures. This invention fully utilizes the characteristics of both materials: in terms of architecture, the structural system can rationally utilize building space; besides the shear wall distribution in the lateral resistance system, the glued laminated timber frame system allows for flexible building partitioning; in terms of structure, the system can fully leverage the lateral resistance of the steel plate shear wall structure and the load-bearing capacity of the glued laminated timber frame structure. Through rational design, the lateral resistance system and the load-bearing system are functionally separated, each performing its specific function. Furthermore, the dampers between the two systems deform and dissipate seismic input energy under frequent earthquakes; under earthquakes of design intensity and rare earthquakes, the lateral resistance system dissipates energy to resist seismic forces. This fully utilizes the hierarchy and arrangement of different structural components within the structural system, enabling the overall structure to form a two-stage reinforced stress characteristic and a post-earthquake functional recovery mechanism, reducing the cost and difficulty of post-earthquake repair.
[0005] The objective of this invention can be achieved through the following technical solutions:

The timber floor slabs (3) and timber beams (21) are connected by an overlapping method.
[0014] Furthermore, the glued laminated timber frames of adjacent layers are bolted together by the node steel plates.
[0015] Furthermore, the node steel plate is L-shaped, and the node steel plate is provided with node steel plate bolt holes. There are 3 sets of node steel plate bolt holes, which are respectively connected to the bolt holes on the wooden columns at both ends in the vertical direction and the wooden beams in the horizontal direction.
[0016] Furthermore, the post-tensioned unbonded prestressing tendon is selected from any one of prestressed steel strand, prestressed steel wire bundle, prestressed fine-rolled threaded steel, or prestressed FRP tendon.
[0017] Furthermore, the anchorage is selected from any one of the following: support anchorage, cone plug anchorage, wedge anchorage, and gripping anchorage.
[0018] The second aspect of this invention provides a construction method for the post-earthquake recoverable steel plate shear wall-timber frame hybrid structure, comprising the following steps:
[0019] S1: Constructing a steel plate shear wall: The steel web is connected to the steel beams and columns by welding or bolting, with cuts at the four corners of the steel web; shear plates are welded onto the steel columns, with oblong holes for shear plates; the ends of the steel beams are provided with first steel beam bolt holes, and steel beam bolts pass through the oblong holes in the shear plates and the first steel beam bolt holes to connect the shear plates and the steel beams; post-tensioned unbonded prestressing tendons are passed through the steel beams and fixed to the steel columns by anchors, thus obtaining the steel plate shear wall;

[0023] Compared with the prior art, the present invention has the following advantages:
[0024] (1) This invention introduces steel plate shear walls into the timber structure, which greatly improves the lateral resistance of the structure. In the steel plate shear wall-timber frame hybrid structural system, most of the lateral forces are borne by the steel plate shear walls, reducing the damage to the timber structure.
[0025] (2) The present invention has good vibration reduction effect and excellent seismic performance. Under minor earthquakes, the steel plate shear wall has good lateral stiffness and can resist horizontal seismic shear force; under moderate or major earthquakes, the steel plate shear wall can bear most of the lateral force, and the self-resetting shear damper between the steel plate shear wall and the glued laminated timber frame fully exerts the function of energy dissipation and vibration reduction through deformation.
[0026] (3) This invention features a self-resetting function, making the structure easy to repair after an earthquake and significantly reducing repair costs. Under moderate or severe earthquakes, the steel plates in the self-resetting shear damper dissipate energy through mutual friction, effectively controlling the deformation of the steel plate shear wall and significantly reducing its damage. The post-tensioned unbonded prestressing tendons on the edge beams of the steel plate shear wall are always in an elastic tension state. Under the action of the prestressing tendons, the structure returns to its initial state with very little residual deformation. If the self-resetting shear damper remains elastic under earthquake action without irreversible deformation or damage, it can withstand multiple earthquakes.
[0027] (4) The present invention uses a large number of prefabricated components, combined with the ease of construction of the wood structure itself, which greatly improves the construction speed and progress of the structure, conforms to the development trend of building industrialization, and has great prospects in practical engineering applications.
