Earthquake-resistant, prefabricated steel tube shear wall hybrid structure buildings

Abstract

The invention relates to a shock-proof prefabricated steel tube shear wall mixed structural building which belongs to the field of buildings. The building is provided with a foundation, wherein the foundation is respectively connected with the lower ends of shear walls and steel columns; the upper ends of the shear walls and the steel columns are connected with steel beams; the shear walls and the steel beams are connected with composite floor slabs; single shear walls on a plane are combined and connected together to form a shear wall barrel body; a vertical upper section of shear walls is connected with a vertical lower section of shear walls; stair treads are connected with supporting beams; and self-bearing masoning filler walls and main body structural components are connected together. The integrity and vibration strength of the connected structural components are reliable, so that the building is safe, economic and durable; steel structural components and steel concrete combined components have good connecting performances, so that the working environment of the operating personnel is improved to the maximum extent, the construction period is shortened, and the construction cost is lowered; and moreover, the structural components of the building are made by steel materials with higher strength, so that a large span is realized, and the building is easy to reconstruct and update after a plurality of years and has high durability.

[0002] As we all know, in recent years, the construction of green, energy-saving and healthy buildings has become our basic national policy. The industrialized engineering construction model marked by standardization and industrialization requires factory-based prefabrication of engineering construction and on-site mechanized assembly. The formwork system required for prefabrication is relatively complicated, the cost is high, the operation of the connection between components is inconvenient, and the integrity is poor, which affects the development of prefabricated buildings. Therefore, it is urgent to find a technical measure to solve these problems; in order to achieve the above goals, the current All parts of the country are actively researching building structure technologies that meet this goal, including steel structure component prefabrication technology, reinforced concrete component prefabrication technology, concrete and steel composite component technology, and on-site assembly and connection technology for these building structural components. A hybrid structure building composed of components; but because the design and manufacturing technology of some structural components, as well as the overall assembly and connection structure of on-site mechanization are unreasonable, the research and development is not enough, and there are many problems that need to be improved urgently; in addition, through recent years In the analysis of earthquake disasters, the seismic design has made great progress, from a single seismic design to a combination of shock absorption and seismic design, and then improved to the seismic design to improve the energy dissipation capacity of structures and components. It is recognized that the improvement of prefabricated building structures Integrity and deformation energy consumption are important measures for earthquake resistance, especially steel structure buildings with the best seismic performance, so it is necessary to vigorously develop prefabricated and steel structure buildings; at the same time, the stairs, structural components and masonry infill walls in the building structure The connecting structure often has problems due to improper handling of the structural structure, which aggravates the earthquake disaster
