At present, there are many styles of architecture, and this style mainly depends on the design of the structure. The investigation found that the current frame shear structure is a very common one. So, what are the advantages of the frame shear structure? Only a detailed understanding of these, In order to better understand the frame-shear structure, in addition, when designing and constructing the frame-shear structure, the characteristics must be understood so that the operation can be better.
The advantages of frame shear wall structure:
1.Frame shear wall structure is also called frame shear structure.This structure is to arrange a certain number of shear walls in the frame structure.This kind of shear wall is called frame shear wall, and they form a flexible and free use space. To meet the requirements of different building functions, at the same time there are enough shear walls, with considerable rigidity. The main function is to withstand the horizontal load caused by wind load or earthquake action in the house building to prevent the structure from shearing damage. It is divided into plane shear wall and three-dimensional shear wall. It is generally made of reinforced concrete and cast-in-place reinforced concrete. The stress characteristics of frame shear walls are mainly the arrangement of a certain number of shear walls in the frame structure to form a flexible and free space for use. The stress characteristics are composed of two different anti-side force structures of frame and shear wall structures. The form of force, the interaction force between the frame and the shear wall makes the whole frame shear wall structure more stable.
2. Frame structure building layout is more flexible and can form a larger space, but the ability to resist horizontal loads is poor, while the shear wall structure is the opposite. The frame-shear wall structure combines the two to take advantage of the shortcomings. Shear walls are arranged between certain columns of the frame to form a structural system with greater bearing capacity and more flexible building layout. In this structure, the frame and the shear wall work together, the frame mainly bears the vertical load, and the shear wall mainly bears the horizontal load.
Features of frame shear structure design and construction:
1. In today's increasingly tense construction land, the architectural design of high-rise frame and shear structures is widely adopted. High-rise frame and shear structures are generally designed in basements, and the foundation is made of fully cast-in-place concrete structures with raft foundations. In the design of high-rise building groups, generally The basement or overhead layer is used to connect with the main buildings, the main building foundation is connected to the basement, and the post-casting belt is set between the foundations of the connecting parts.The general design requirements of the post-casting belt are to be cast after the main building main body is capped. The height and the number of layers are different. The steel content per square meter is between 55kg and 85kg. The steel used in the design is generally used as the main load-bearing steel bars. The second-level steel and the third-level steel are used. For the second-grade steel and first-grade steel, the concrete design generally adopts three grades of concrete: C50, C40, and C35, and some adopt the grades of C55 and C60.
2. At present, the more popular processes for frame-shear structure construction are: using steel pipe scaffolding on site as a load-bearing and supporting system, using on-site processing wooden templates as forming molds for concrete members, and steel bars using straight thread connection and vertical butt welding; urban city Commodity concrete is used for construction in the district. Large-scale mixing stations can be set up in the suburbs when construction conditions permit. Concrete pouring pumps are used for pouring concrete. Vibration and tamping are carried out by plug-in vibrators. Vertical transportation uses tower cranes and construction elevators.
Through the above introduction, I believe that everyone has certain advantages for the frame-shear structure.The frame-shear structure is not only flexible in layout, but also able to withstand vertical loads. In addition to these, there are many advantages, but whether to adopt it, you still need to understand the actual In addition, in the construction of frame-shear structure, there must be a certain complete specification, so as to better design.
