Earthquake-resistant, prefabricated reinforced truss-shear-wall hybrid buildings

Abstract

The invention relates to an earthquake-resistant, prefabricated reinforced truss shear wall mixed structure building, which belongs to the construction field. Prefabricated perimeter reinforced truss concrete shear walls with steel frames, laminated slabs with prestressed concrete slabs, foundation and steel column connection, foundation and shear wall connection, steel column and steel beam connection, steel beam and laminate The connection of the floor, the connection of the steel beam and the shear wall, the connection of the shear wall and the laminated floor, the connection of the upper and lower parts of the shear wall, the connection of the steel column and the shear wall, the combined connection of the steel beam and the shear wall . The integrality and shock resistance of the connection between the structural members of the present invention are reliable, ensuring building safety, economy and durability; steel structural parts and steel-concrete composite members have good connection performance, which improves the working environment of operators to the greatest extent, shortens the construction period, reduces At the same time, the structural components of this building use high-strength steel, which can achieve a large span. After a few years, the building is easy to refit and update, and can reflect 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
