How to draw a shear wall, how to draw a shear wall

Drawing Method: Arranged shear walls.

As long as the column that can be contacted, no matter where it is, the calculated amount of reinforcement is the same, that is to say, it does not affect the calculation of the reinforcement, and the shear wall is full at the position of the dark column, it should be considered according to the local quota rules, such as the dark column is calculated according to the shear wall, then the shear wall is full, and the position of the dark column will not be empty after the graphical calculation is imported.

Shear walls are also known as wind-resistant walls.

Seismic walls or structural walls.

Walls in houses or structures that are mainly subjected to horizontal and vertical loads (gravity) caused by wind loads or ** actions to prevent structural shear (shear) damage.

It is divided into plane shear wall and cylinder shear wall. Flat shear walls are used for reinforced concrete.

In frame structures, rising plate structures, and beamless floor systems. to increase the stiffness of the structure.

Strength and collapse resistance, in some parts can be cast-in-situ or prefabricated reinforced concrete shear walls. The cast-in-situ shear wall is poured at the same time with the surrounding beams and columns, and the integrity is good. Barrel shear walls are used in high-rise buildings.

In the high-rise structure and suspension structure, it is surrounded by the partition wall of the elevator room, the stairwell, the equipment and the auxiliary room, and the cylinder wall is a cast-in-place reinforced concrete wall, and its stiffness and strength are higher than the plane shear wall and can bear a large horizontal load.

In the component definition, first define the shear wall, wall thickness, reinforcement, etc., and then draw it on the drawing interface The shear wall is a reinforced concrete cast-in-situ wall, and its main role is shear resistance.

What is a Shear Wall? Shear Wall Atlas? Many people must be very unfamiliar with this issue. Today, let's popularize science with you and increase a little engineering knowledge.

What is a Shear Wall?

According to the stress characteristics, the wall can be divided into load-bearing wall and shear wall, the former is mainly to bear vertical load, such as masonry wall; The latter is dominated by horizontal loads. In the seismic fortification area, the horizontal load is mainly generated by the horizontal ** action, so the shear wall is sometimes called the seismic wall.

The shear wall structure is a load-bearing system composed of reinforced concrete walls. Vertically it is a reinforced concrete wall panel, and horizontally it is still a reinforced concrete floor slab carrying the wall. Another:

In the frame structure, the rectangular space between the frame beams and columns is sometimes set up as a cast-in-place reinforced concrete wall to strengthen the spatial stiffness and shear resistance of the frame, and such a structure is called a frame-shear wall structure.

In the reinforced concrete structure, part of the shear wall can not land because of the building requirements, directly falls on the lower frame beam, and then the load is transmitted to the frame column by the frame beam, such a beam is called a frame support beam, the column is called a frame pillar, and the upper wall is called a frame support shear wall. If the structure consists of one or more vertical cylinders (thin-walled cylinders surrounded by shear walls or frame cylinders composed of dense column frames), it is called a cylinder structure.

The shear wall structure includes one wall, two columns, and three beams, that is to say, it contains one wall body, two kinds of wall columns, and three kinds of wall beams.

1. A kind of wall.

The wall of the shear wall is a concrete wall, with a common thickness of more than 200mm, and is generally equipped with two rows of reinforcement mesh.

2 Two types of wall columns.

Shear wall columns are divided into two main categories: dark columns and end columns.

The width of the dark pillar is equal to the thickness of the wall, so the dark pillar is hidden inside the wall and cannot be seen. The width of the end posts is larger than the thickness of the wall, and the dark columns and end posts are collectively referred to as edge members in the atlas because these members are set at the edge of the base of the wall limb. Edge members are further divided into two main categories:

Construct edge components and constrain edge components.

3. Three kinds of wall beams.

Connecting beams (LL), dark beams (AL), and frame beams (BKL).

Connecting beams: Connecting beams are actually a special kind of wall, which is the part of the blind window wall between the windows (doors) openings on the upper and lower floors.

Dark Beams: Dark beams have some commonalities with dark columns, as they are both invisible components hidden inside the wall. They are all an integral part of the wall.

In fact, the dark beams of the shear wall and the ring beams of the brick-concrete structure have something in common, they are both sharpened and act as a parallel reinforcement zone for strengthening. It is generally installed under the floor slab.

Frame beam: Frame beam and dark beam have a lot in common, frame beam is also generally set below the floor slab, but the cross-sectional width of the frame beam is wider than that of the dark beam. That is, the cross-sectional width of the frame beam is greater than the thickness of the wall, thus forming a frame that protrudes from the shear wall.

First, the role and location of the concrete cushion block:

1. It is used to ensure the thickness of the concrete protective layer;

2. At the place of contact with the template.

Second, the shear wall structure layout and practice:

1. The shear wall structure is composed of longitudinal and transverse reinforced concrete walls, and the vertical load, wind load and action are borne by these walls.

2. For high-rise shear wall structure, the wall should be arranged in both directions or in multiple directions to form a plane and vertical layout that is favorable to bear vertical loads and has large lateral force stiffness. In the seismic structure, the structural layout with only one-way walls should be avoided, and the lateral stiffness of the shear wall structure should not be too large. The shear wall spacing should not be too dense, and it is advisable to use a large bay layout.

The shear wall should be continuously arranged from bottom to top to avoid sudden change in stiffness.

3. The structure of high-rise buildings should not adopt the shear wall structure of all short limb shear walls. The short limb shear wall refers to the shear wall with the ratio of the height of the wall limb section to the thickness of 5 8, and the general shear wall refers to the shear wall where the ratio of the height of the wall limb section to the thickness is greater than 8.

4. The height-width ratio limit of high-rise shear wall structure is shown in the table and the table. The foundation of a high-rise shear wall structure should have a certain depth of embedding (see Chapter 11 for details). It is advisable to set up a basement.

5. The longer shear wall can be divided into a number of independent wall segments more evenly with a weak connecting beam with a span-height ratio of not less than 5, and each independent wall segment can be an integral wall or a connecting wall, and the ratio of the total height of each independent wall segment and the length of the wall segment should not be less than 2, so as to avoid shear damage and improve the deformation capacity. Each wall segment has a plurality of wall limbs, and the length of each wall limb should not be greater than 8m. When the length of the wall limb exceeds 8m, the structural hole method of leaving a hole in the wall during construction and building the infill wall when it is completed should be adopted, and the long wall limb should be divided into short wall limbs, or only the hole should be opened in the calculation diagram.

It is used to ensure the thickness of the concrete protective layer. at the place of contact with the template.

The shear wall of the frame shear structure is arranged with the 8-character policy, that is, the "periphery, uniform symmetry, intersection" bottom frame structure mountain wall is generally arranged with a shear wall, because it is not suitable to arrange the bottom frame structure of the concrete perseverance wall on both sides of the stairwell of each residential unit.

The relevant tests show that increasing the plane stiffness at both ends of the empty house on the ground floor and controlling the vertical displacement at the end of the bottom frame can effectively increase the safety reserve of the bottom layer frame, but despite this, the layout is not all around, and a lot of shear walls are needed in the middle. Therefore, the bottom frame structure 8-character policy can be summarized as vertical, uniform, symmetrical, and effective", and the pants are vertical, which is to correspond to the upper and lower vertical and uninterrupted wall in the middle when arranging the bottom shear wall, otherwise even if the stiffness of the shear wall leakage of the bottom layout draft is large, if there is no corresponding upper wall vertically, not only the force transmission path is not direct, but the upper and lower rigid centers are far apart, and the upper and lower layers will form a large torque between the upper wall and the bottom shear wall, which is very easy to destroy.

In addition, when arranging the bottom shear wall, it is necessary to avoid the opening of the upper wall, if it is really difficult to avoid the specific implementation, (such as the entrance door of the stairwell, etc.), then strengthening measures such as adding structural columns on both sides of the upper opening should be taken to better transmit the force. For individual shear walls that fail to correspond to the upper brick walls, efforts should be made to increase the in-plane stiffness of the floor slab between the ground floor and the second floor conversion layer, such as thickening the floor slab, increasing the reinforcement ratio, and two-way double-layer reinforcement. The intersection mainly means that the shear wall should be arranged in an L-shaped and T-shaped as much as possible, so that they support each other, increase the out-of-plane stiffness of each single-limb wall, and enhance the torsional resistance.

The length and opening of the shear wall need to be determined by calculation. After the calculated length of the shear wall is determined, the solid wall should be arranged in the middle of the two ends and separated by a hole, so as to avoid the key rotting method of having a shear wall at one end and an independent column at the other end. In short, when the concrete shear wall is specifically arranged, it is advisable to open openings to form a number of wall segments, and ensure that the height-width ratio of each wall section is not less than 2.
