What is the difference between longitudinal and transverse reinforcement?

Distinction between longitudinal and transverse:

Reinforced concrete structure.

The vertical reinforcement of the middle column is the longitudinal reinforcement, and the horizontal reinforcement (stirrups.

It is the transverse reinforcement;

The longitudinal reinforcement perpendicular to the ground in the wall, and the transverse reinforcement parallel to the ground;

The reinforcement at the bottom and top of the beam along the beam span direction is longitudinal reinforcement, and the stirrups and tension bars of the beam are transverse reinforcement;

The transverse reinforcement is the short direction along the floor slab, and the longitudinal reinforcement along the long direction of the floor slab.

Reinforcement parallel to the longitudinal axis of the concrete member.

The reinforcement configured in the compression zone of the section is called the longitudinal compression reinforcement;

The reinforcement that is placed in the tension zone of the section is called the longitudinal tension reinforcement.

The vertical reinforcement of the column in the reinforced concrete structure is the longitudinal reinforcement, and the horizontal reinforcement (stirrups) is the transverse reinforcement; The longitudinal reinforcement perpendicular to the ground in the wall, and the transverse reinforcement parallel to the ground; The reinforcement at the bottom and top of the beam along the beam span direction is longitudinal reinforcement, and the stirrups and tension bars of the beam are transverse reinforcement; The transverse reinforcement is the short direction along the floor slab, and the longitudinal reinforcement along the long direction of the floor slab.

Longitudinal reinforcement in columns, walls, and beams resists tensile and compressive forces, and transverse reinforcement resists shear forces. For two-way slabs, the longitudinal and transverse reinforcements are the main stress bars; The transverse reinforcement in the unidirectional plate is the stressed bar, and the longitudinal reinforcement is the distributed bar.

The vertical reinforcement of the column in the reinforced concrete structure is the longitudinal reinforcement, and the horizontal reinforcement (stirrups) is the transverse reinforcement; in the wall and in the ground.

The surface is perpendicular to the longitudinal reinforcement, and the parallel to the ground is the transverse reinforcement; The bottom and top of the beam are longitudinal in the direction of the beam span.

To the reinforcement, the stirrups and tension bars of the beam are transverse reinforcement; The transverse reinforcement is the short direction along the floor slab, and the longitudinal reinforcement along the long direction of the floor slab.

Longitudinal and transverse bars are distinguished by the direction of the axis, parallel to the axis direction is the longitudinal bar, perpendicular to the axis direction is the transverse bar.

You can take the drawing as a plane and draw a grid from it, with the x-axis of the reinforcement being the transverse reinforcement and the y-axis being the longitudinal reinforcement.

Distinguished by letters, x for landscape and y for portrait!

The rebar and the transverse rebar should be reinforced by one of his layouts to enhance a division, and the distribution of his stripes can be known, which should be able to better guide her on how to distinguish them.

You're talking about walls, the horizontal reinforcement should be horizontal reinforcement, and the vertical reinforcement should be vertical reinforcement.

Are you talking about plates or other components? The horizontal is horizontal, and the vertical is vertical.

Longitudinal reinforcement generally refers to the main stressed steel bar in the length direction, and the steel bar arranged along the long direction in the concrete component is mostly stressed steel bar, which mainly bears tensile force in the component. : Vertical reinforcement such as columns.

The reinforcement of the beam along the length of the beam. The long direction of the reinforcement of the slab. Vertical reinforcement of piles.

Walls are generally represented by vertical and horizontal reinforcement. Post. Beams are generally not called transverse bars.

It's all called stirrups. Transverse reinforcement is a short-direction reinforcement. Such as the short direction of the plate actually:

The reinforcement in the main direction of force should be called longitudinal bars. Its vertical direction is the transverse bar. To avoid misunderstandings.

Columns are recommended. Beam. Piles, etc. can be referred to as longitudinal bars.

Stirrups. The wall is called vertical and horizontal. The plate is called a short bar and a long stirrup.

Longitudinal stress reinforcement refers to the compression or tension in the length direction of the component (in most cases), and also includes several other forms of tension, compression, bending, shearing and torsion.

For beams, columns, and diagonal brace components (including rungs), longitudinal reinforcement refers to the reinforcement along the length of the member.

For the plate there is no longitudinal reinforcement, the flat standard is the stressed reinforcement along the X or Y direction.

There is no longitudinal reinforcement for the shear wall, only vertical and horizontal distribution reinforcement. The vertical reinforcement of the dark columns, end columns, wing columns, buttresses and so on of the shear wall is the longitudinal reinforcement.

Longitudinal stressed steel bar, referred to as stressed steel bar, refers to the long side direction of the component, through mechanical calculation, the stressed part of the steel bar to meet the bearing capacity to meet the requirements of structural strength and stiffness. The lower or upper part of the common bending beam is the stressed steel bar, and the compression steel bar in the column belongs to the longitudinal stressed steel bar.

What is longitudinal: the direction parallel to the direction of the distributed load, that is, the longitudinal;

According to this concept, and the reinforcement is stressed, structural reinforcement (construction), tie reinforcement (construction), torsion reinforcement, stirrups, and transverse reinforcement can be excluded.

The surface layer of the beam is long ribs, the bottom layer is long ribs, and the vertical ribs of the column, the stirrups are like the bottom distribution ribs of the slab.

Horizontal steel bars and vertical steel bars such as railings and gutters.

Construct the long ribs of columns and ring beams.

All the steel bars in the industrial and civil construction are set up by taking advantage of its strong tensile strength, and macroscopically speaking, the steel bars placed in the concrete are all stressed tendons! (And it's all tensile force), otherwise, wouldn't it be a waste to stuff it in concrete!

However, the "longitudinal stress reinforcement" referred to in the industry only refers to the reinforcement that has been calculated by the structural force and arranged along the long direction of the component. From this point of view, the upper part of the beam is filled with long ribs, negative reinforcement of the support, torsional reinforcement, and bottom reinforcement; Vertical reinforcement of columns; The bottom longitudinal reinforcement and negative reinforcement of the plate are "longitudinal stressed reinforcement". Stirrups, hanging bars, additional stirrups, overhangs and ditch transverse reinforcements, etc. are "transverse stressed reinforcements"; Others, such as distribution bars, erection bars, temperature bars, tie bars, structural columns and ring beams, are all structural reinforcements.

The longitudinal reinforcement and transverse reinforcement generally speak of the reinforcement of the beam column, and the longitudinal reinforcement is the reinforcement in the long direction, that is, the main reinforcement and the stressed reinforcement. The transverse bars are the reinforcing bars in the short direction, which are stirrups.

Generally, the stressed steel bar in the beam or slab is called longitudinal reinforcement, and the transverse reinforcement has almost no such word; When it comes to transverse reinforcement, it is probably relative to longitudinal reinforcement on the drawing, but most of them are called structural reinforcement. I'm sorry to give you such an unprofessional answer as someone who has been doing structural design for five years, but I really didn't understand what a horizontal rib is, if I can see the specific drawings or **I think I can explain it.

Longitudinal bars generally refer to stressed reinforcement, rather than drawing directions and the like.

For example, the bottom steel bars of the slab in the x, x and y directions are all longitudinal rebars.

1.In plate reinforcement, the longitudinal reinforcement refers to the parallel and x-direction of the steel bar that is the direction of the drawing is shorter, and the transverse reinforcement refers to the direction of the parallel to the y-direction of the reinforcement drawing is longer.

2.The longitudinal and transverse reinforcement in the beam reinforcement and plate reinforcement are the same, and there is no difference.

3.In reinforced concrete structures, the vertical reinforcement of the columns is the longitudinal reinforcement, and the horizontal reinforcement or stirrups are the transverse reinforcement.

4.The wall is perpendicular to the ground for longitudinal reinforcement, parallel to the ground for transverse reinforcement, and the bottom and top of the beam along the beam span direction of the steel bi rotten reinforcement are longitudinal reinforcement, the stirrups and tension reinforcement of the beam are transverse reinforcement, the short direction along the floor slab is the transverse reinforcement of digging and leakage, and the long direction along the floor slab is the longitudinal reinforcement.

Summary. Longitudinal reinforcement and transverse reinforcement which is on which which is in the foundation engineering of the lower construction engineering one is raft reinforced concrete foundation, according to the principle of stress of reinforcement longitudinal reinforcement are in the lower part (short length of reinforcement), transverse reinforcement in the upper part, the other is the foundation beam reinforced concrete structure, the foundation beam stressed reinforcement in the lower part, (diameter thick steel bar) non-stressed steel bar in the upper part, (diameter fine steel bar), the drawings have instructions, no matter which one must be strictly in accordance with the drawings description of the construction.

Which is on top and which is on the bottom.

Hello, upon inquiry:

Longitudinal reinforcement and transverse reinforcement which is on which in the foundation engineering of the construction project is a raft reinforced concrete foundation, according to the principle of force of the reinforcement longitudinal reinforcement are in the lower part (short length of the reinforcement), transverse reinforcement in the upper part, the other is the foundation beam reinforced concrete structure, the foundation beam stressed reinforcement in the lower part, (diameter thick steel bar) pure annihilation non-stressed clear reinforcement in the upper part, (diameter fine steel reinforcement), the drawings have to do careful instructions, no matter which one must be strictly in accordance with the drawings description of the construction.

The short span direction is placed below, and the long span direction is placed on the Qi side judgment surface, because the short span is the main stress party Qichun to the high change, the short direction along the floor slab is the transverse reinforcement, and the long direction along the floor slab is the longitudinal reinforcement.
