Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to an integral rotating structure under strong earthquakes and its construction method. Background Technology

[0002] Traditional seismic-resistant systems rely on the inelastic deformation of key structural members to dissipate seismic energy, thus protecting buildings from collapse. While current building codes are generally considered to provide sufficient safety, their requirements focus on lateral strength and ductility, without explicitly controlling the amount of structural and non-structural damage or specifying requirements for continued use after an earthquake. The damage to key structural members (including braces, walls, beams, columns, and connectors) and residual drift caused by earthquakes can make post-earthquake repair uneconomical or impossible. Earthquake engineering for foundation performance highlights the importance of reducing maintenance costs and preventing building failure; higher performance can be achieved by minimizing inelastic deformation and damage to key structural components. Generally, reinforcing traditional seismic-resistant systems to achieve this performance is neither practical nor economical. Instead, new approaches are needed.

[0003] Therefore, designing a structural system that is easy to construct and maintain, cost-effective throughout the building's life cycle, prevents major structural damage during major earthquakes and minimizes residual displacement, and can be used again with minor repairs is of great research value.

[0022] Step seven: Construct the frame beams and connecting beams. This completes the construction of the overall rotating structure for strong earthquakes.

[0023] Compared with the prior art, the present invention has the following features and beneficial effects.

[0024] 1. This invention achieves the swaying and post-earthquake self-resetting functions of the structure by using a rotating energy-dissipating support set at the center of the structure and vertical tensile and compressive elastic supports set around the structure, which can effectively improve the seismic toughness of the structure. Among them, the tensile and compressive elastic supports set around the structure effectively dissipate seismic energy, greatly improve the seismic performance of the structure, prevent major structural damage during a major earthquake, and minimize residual displacement.

[0025] 2. In the overall rotating structure of this invention, the superstructure can be constructed using traditional methods, avoiding the complexities of construction at numerous nodes in the original swaying structure and saving significant construction costs. This invention, by installing tensile and compressive elastic energy-dissipating supports and rotating energy-dissipating supports at the bottom of the side and central columns, enables the entire structure to become a controllable swaying structure during moderate to severe earthquakes. This reduces the overall sway amplitude and allows for wider application of swaying structures in practical engineering projects.

[0026] 3. The superstructure of this invention adopts a frame structure, which avoids the construction complexity of a large number of nodes in the original swaying structure, reduces construction costs, avoids the setting of a large number of prestressed tendons in the structural system, simplifies the construction process, is more conducive to improving construction efficiency, and is more conducive to ensuring the engineering quality of the building structure.

[0027] 4. This invention changes the original swaying pattern along the length of the building into a rotating swaying structure, thereby reducing the swaying amplitude of the overall upper structure.

[0028] 5. This invention uses the central column as the rotation axis and the rotating energy-dissipating support at the bottom of the central column as the rotation point. When an earthquake occurs, the entire superstructure undergoes rigid body rotation and swaying. The tensile and compressive elastic energy-dissipating supports set at the bottom of each side column and the rotating energy-dissipating hinge support set at the bottom of the central column dissipate energy, which can effectively reduce the seismic acceleration and displacement response of the structure, so that the superstructure is in an elastic working state.

[0049] The construction method for this type of integral rotating structure during strong earthquakes includes the following steps.

[0051] Step 2: Install elastic telescopic energy-dissipating components 5 at intervals on the four side walls of the cup base 2 slot.

[0052] Step 3: Precast the central column 1.1, side columns 1.2, connecting beams 1.4 and frame beams 1.3.

[0053] Step 4: Install the first steel sleeve 7 and the first base plate 8 at the bottom of the central column 1.1, and install the rotating energy dissipation support 4 at the bottom of the first base plate 8; at the same time, install the second steel sleeve 10 and the second base plate 11 at the bottom of the side column 1.2, and install the tensile and compressive elastic energy dissipation support 6 at the bottom of the second base plate 11.

[0057] When the structure is subjected to seismic forces, each structural unit rotates around the central column 1.1 as its axis of rotation and the rotating energy-dissipating support 4 at the bottom of the central column 1.1 as its rotation point. The upper structure of each structural unit undergoes rigid body rotation and swaying. Seismic energy is dissipated through the tensile and compressive elastic energy-dissipating supports 6 at the bottom of each side column 1.2 and the rotating energy-dissipating support 4 at the bottom of the central column 1.1. The structural units are connected by energy-dissipating components, which dissipate some of the energy input between the units due to the seismic motion. These components also withstand the tensile and compressive internal forces generated in the energy-dissipating components due to the swaying of the structural units during the seismic event, thus forming an energy-dissipating swaying pattern for the entire structure. During moderate and major earthquakes, the overall structure achieves controllable swaying through the interconnected rotation and swaying of the structural units, thereby altering the original swaying pattern along the length of the building structure. By designing a modular rotating structure for strong earthquakes, the structural sway amplitude is controlled to a certain extent, while also effectively limiting the inter-story deformation requirements and dynamic response of each modular unit, thereby avoiding damage to the superstructure components. Due to the replaceability of the tensile-compressive elastic energy-dissipating supports 6, the rotating energy-dissipating supports 4, and the energy-absorbing components in each modular unit, the structure possesses a certain degree of post-earthquake recoverability.

[0058] The above embodiments are not exhaustive examples of specific implementation methods, and other embodiments are also possible. The purpose of the above embodiments is to illustrate the present invention, rather than to limit the scope of protection of the present invention. All applications derived from simple variations of the present invention fall within the scope of protection of the present invention.
