What is a half frame structure What is a half frame structure? What are its features?

There are three main structural methods in the building: frame structure, brick-concrete structure and frame-shear structure.

Semi-frame structure is a common name for people, there is no such term in the national norms, and it is generally considered that a semi-frame structure is a house that has both a frame and other types of structures.

Most of the buildings seen have a semi-frame structural system. For example, the high-rise residential buildings around you are mostly reinforced concrete frame beam structural systems, and then the staircase barrels and elevator barrels in the middle part are shear wall structural systems. Then it is commonly known as a frame shear wall structure, and it is also commonly known as a semi-frame.

There are also some buildings with a mixture of frame structure and brick-concrete structure, but most of them are relatively small and multi-storey. There are also some small temporary buildings, such as landscape spots and temporary sales offices, which are mostly built with a combination of steel structure and brick-concrete frame structure.

There are problems with the above, most of the frames on the first floor, the bathroom stairwell is cast-in-situ, it is called a half frame? That's called"Frame-shear wall structure"This concept has been around for a long time, but it is not called a framework structure.

Second floor: that is called the mixed structure (this is also the common name), now the half-frame is indeed a common name, so there is no fixed definition, it refers to: the force mode between the frame and the brick-concrete structure of a situation, because the frame is the beam and column stress, the wall only plays the role of enclosure insulation and isolation, pure not load-bearing, and the brick-concrete structure is the wall load-bearing, the beams and columns inside only play the role of earthquake resistance, strengthen the integrity and strengthen the stiffness, so the half-frame is the beam and the wall are stressed, However, the force of collecting is not as large as that of pure frame or pure brick-concrete, so the reinforcement inside the beam is smaller than that of the frame cheek beam, and larger than that in the brick-concrete structural ring beam, and the wall can not directly use non-load-bearing hollow bricks, but should use perforated bricks that can bear load. Got it?

Hello: Semi-frame structure refers to a part of a frame structure and a part of a brick-concrete structure. For example, in the façade house on the side of the street, the frame structure is below, and the brick and concrete structure is above. Good luck!

Blaze Sun - Trial Period Level 1 You're talking about the bottom frame structure.

Semi-frame structure is commonly known as the reinforced concrete frame beam structure system, and then the stair barrel and elevator barrel in the middle part are the shear wall structural system, and then commonly known as the frame shear wall structure, commonly known as the semi-frame. There is no such statement in the national code, and it is generally considered that a semi-frame structure is a house with both a frame and other types of structure.

You can understand it so simply: a half-frame structure is also called a brick-concrete structure! Different from the pure frame structure, it is the main structure that uses prefabricated slabs for floor slabs and door frame lintels, and brick walls as load-bearing walls!!

What is a semi-frame structure? What are its features?

Semi-frame structure is commonly known as the inner frame, which is not used in national norms, and it is generally considered that a semi-frame structure is a house with both a frame and other types of structures. Generally common: it is all around the brick wall (some are shear wall structure, but it is very rare), and the inside is called the inner frame by the columns.

It is to stare at the bottom layer to make a large room, and do not want to make a local frame structure of all the bottom frames, this kind of structure seismic Kai type is very unfavorable, and the current seismic code has prohibited the use of this structural form. The characteristics are: reinforced concrete frame beam structural system, and the stair barrel and elevator barrel in the middle part are shear wall structural systems.
