Description
Technical Field
The invention relates to a frame structure system for earthquake resistance and energy consumption of a common multi-layer house, in particular to a frame structure with energy consumption diagonal braces, wherein split column frame nodes are formed by dry connection of steel sleeves, and the frame structure system relates to the field of earthquake resistance of constructional engineering and structures.
Background
China is a country with frequent earthquakes, and in the past earthquake, structural damage, casualties and property loss caused by insufficient earthquake resistance of the reinforced concrete column account for a considerable proportion of structural earthquake disasters. Therefore, research on improving the seismic performance of reinforced concrete columns has been an important focus of structural engineers.
Reinforced concrete split column technology was proposed in the past decade of our country, and many students have developed it for structural anti-seismic middle (Hao Yong et al, 1998, 1999; li Zhongxian et al, 2001, 2002, 2003, 2007; ding Baofen et al, 2012; li Yaping, 2012; li Bingyi et al, 2008; xu Zhenji et al, 2013; wang Songshan et al, 2016; liu Fangcheng et al, 2021). The results show that: the split column has better ductility and deformation energy consumption capability, and can play an effective anti-seismic role in engineering.
With the development of modern society, most of the traditional industries are coming to be revolutionized. In the same way, the defects of the cast-in-situ reinforced concrete structure are gradually revealed, such as the casting compactness of a node core area, environmental pollution, too long construction period and the like. What is decisive for the safety and reliability of the fabricated building is the connection of the beam-column joint core area. Expert scholars at home and abroad aim to solve the problem, and a great deal of experiments and researches are carried out aiming at the connection form and anti-seismic characteristics of the beam column node core area of the assembled frame structure (E. Irtem et al 2001;Hossein Parastesh et al, 2014; dongzhi Guan et al 2016; jose F. Rave-Arango et al 2018;Qiushi Yan et al, 2018; J.D. Nzabonima et al, 2018; yang et al 2019;Huang Wei et al, 2021). The assembled frame structure has great development prospect, and the steel sleeve has the characteristic of high rigidity, so that the node of the assembled frame structure has higher stability. Research on the energy consumption support at home and abroad is also mature gradually, and the problem that the horizontal displacement of the split column frame structure is large when the energy consumption support is arranged in the frame structure and can resist the attack of an earthquake is solved.
In the anti-seismic research of the existing split column technology, researchers have proposed a steel concrete combined split column (Liu Chaodeng, 2022), a rubber separated split column (Liu Xuemin and the like, 2022), a self-resetting friction ductility split column (Ma Qianying and the like, 2022) and the like, most of the research is directed at the assembly form of the split column, the invention provides a split column frame structure assembly form, and the split column frame structure assembly form uses energy-consuming supports to promote the split column to consume seismic energy to the greatest extent through interlayer displacement, so that the split column and the energy-consuming supports supplement each other, thereby being more in line with the development strategy of the national assembly type building and being suitable for being widely applied to practical construction.
Therefore, the assembled split column frame structure with the energy consumption diagonal braces is innovative and has effective anti-seismic significance.
Disclosure of Invention
The invention aims to solve the problems in the background art, and designs an assembled split column frame structure with an energy-consumption diagonal brace, the basic form of which is shown in figure 1.
The technical scheme of the invention is that the assembled split column frame structure with the energy consumption diagonal bracing comprises a reinforced concrete split column (1), a steel sleeve node connecting piece (2) and a buckling restrained energy consumption support (3).
The steel sleeve node connection (2) is divided into two types: one is a node steel sleeve connecting piece in a split column, and the other is a node steel sleeve connecting piece at the end of the split column.
The node steel sleeve connecting piece in the split column is used for column-column connection of a split column frame structure, and the geometric characteristic parameters are as follows: height H of steel sleeve 1 The thickness h of the steel sleeve steel plate and the length and width L of the steel sleeve are shown in figure 2.

Each small column in the split column (1) is overlapped in batches, and the split columns (1) are bound through the steel sleeve joint connecting piece (2) to be connected in a staggered mode, as shown in fig. 4.
The shock insulation mechanism of the assembled split column frame structure with the energy consumption diagonal bracing is as follows: when the earthquake causes the building structure to vibrate, the reinforced concrete split column (1) is better in ductility, the acceleration response of the earthquake is slowed down, the steel sleeve joint connector (2) firmly constrains the column-column and the beam-column together, the small columns of the split column (1) are lapped in batches at the end nodes and the middle nodes, the rigidity of the frame structure nodes is improved, the buckling constraint energy consumption support (3) can apply reverse tension in the deformation process of the reinforced concrete split column (1), and the reinforced concrete split column (1) can consume earthquake energy by utilizing larger interlayer displacement relative to the conventional frame structure, so that the reinforced concrete split column (1) is prevented from breaking and damaging.
The beneficial effects are that:
the invention provides an assembled split column frame structure with energy consumption diagonal braces, which has the beneficial effects that the ductility of a reinforced concrete column is improved from the structural aspect of the frame structure column, the reinforced concrete split column replaces an integral column, the split columns are connected in a constraint manner through steel sleeves, a frame structure beam is connected with the steel sleeves on the split column in a binding manner through bolts, and buckling energy consumption supports are arranged between the columns. The split column has strong deformation capability when an earthquake occurs, so that the split column has an effective buffering effect on the kinetic energy of the earthquake; the steel sleeve node connecting piece can play a role in restraining and protecting the frame structure nodes; the interlayer displacement of the split column frame is effectively controlled by the arrangement of the energy dissipation support, and meanwhile, the earthquake energy is consumed by utilizing the larger interlayer displacement of the split column frame relative to a conventional frame structure. The structure of the invention has effective shock resistance, and can play a role in buffering and dissipating energy of earthquake energy, thereby achieving the safety and stability of the structure, and having convenient construction and strong practicability.
