What size columns and beams should be used to be safe and reasonable?

A 50cm square column is an exaggeration, so it's best to find a structural design for you to calculate.

In addition, the upstairs talk is too crazy, the experience of construction is the first, don't think that it is great to learn a little, these workers have seen a lot of people from south to north, although they can't say the reason, but according to experience, what they say also has a certain truth.

It is best to ask professional unit personnel to design, which is economical and safe.

In addition, I don't know if the other floors of the house you will build in the future are still frames, if they are still frames, you should also consider the column head reinforcing and its rust prevention problems, and try not to consider planting reinforcement in the future.

Supplement: For the problem of ground endurance, it is more convenient and accurate to inquire about the local geological department or design and construction unit than here.

According to what you said, it looks like an independent foundation, there is no wall inside, and there are only 18 walls on three sides outside, the dead load of the house is not too large, if the live load in the future is only 200-250kg m2, the geometric size of the column 500*500mm and 450*450mm is still OK, but the foundation is a little unsatisfactory, it is recommended that you make a plate and strip beam foundation, increase the foundation beam, and the key is the reinforcement and seismic grade requirements.

Finally, it is recommended that you find a professional architectural designer to make a design according to your use requirements, which is reasonable and safe.

The opinions of the construction workers are honed in practice, so judging by what you said above, what they say makes sense! But if you have the money, you can do it your own way!

en It's better to calculate the safety point, and it is recommended to find someone to calculate it.

The construction workers know something.

They're not designing.

Trust in your abilities and the process of calculation.

First of all, the columns are vertical structures, while the beams are transverse structures.

Secondly, the columns are longitudinally loaded, while the beams are transversely loaded.

Finally, the column is carried at both ends. The beams are fully loaded.

A column is the vertical main structural element of a building, supporting the weight of the object above it.

In Chinese architecture, beams and columns are responsible for supporting the weight of the beam structure and other parts, such as the eaves, and there is often a column base between the main column and the foundation. In addition, there are other smaller columns, which are not placed on the foundation, but on the beam frame to support the weight of the objects above, and then transfer the weight to the main column through the beam frame structure. For example, the ridge melon column or Shu column is the weight of the eaves that supports part of the beam frame.

The components that are supported by the support, the external force borne by the transverse force and the shear force, and the bending as the main deformation is called the beam.

Obviously, the column refers to the longitudinal load, that is, the standing force acts at both ends! And the beam is transversely loaded, and there is a load on the entire beam!

Follow-up question: But some pillars are made very wide, like walls, so how do you distinguish them?

You're probably talking about shear walls.

First of all, the column is a vertical structure, the beam is a transverse structure, and when the column is connected with the beam again, it is mainly a column, supplemented by a beam, and when calculating the engineering quantity, the beam is only counted to the side of the column.

The pillars are vertical and the beams are horizontal.

Summary. Hello, I have seen your question and am sorting out the answer, please wait a while Oh how to calculate how big the column is used for the steel structure and how big is the beam used.

Hello, I have seen your question, and I am sorting out the answer, please wait for a while You are too general, this should be determined according to the load (how much weight to bear on the top) and span (how far away to have a column), as well as your local ** intensity, etc., the calculation process is complex, and the complex space structure will be difficult! Most of the calculation methods are now calculated by some design software, such as 3D3S PKPM, etc., which is efficient and accurate!

Can you tell me how big the column and the main beam and the secondary beam need to be.

Changhao Que Kai uses calculation software PKPM, 3D3S, SAP2000, etc., the beam and column section is preliminarily determined according to the empirical value (you need to meet the length stress ratio), and the stable stress ratio, strength stress ratio, displacement, and deflection are checked after the initial determination.

How big it needs to be. No.

First of all, the columns are vertical structures, while the beams are transverse structures.

Secondly, the columns are longitudinally loaded, while the beams are transversely loaded.

Finally, the column is carried at both ends. The beams are fully loaded.

The column is the vertical main structural member of the building, supporting the weight of the orange group of objects above it.

Architecture in China.

In the middle, the beam is a straight column, and the column array is responsible for supporting the weight of the beam frame structure and other parts, such as the eaves, and there is often a column base between the main column and the foundation. In addition, there are other smaller columns, which are not placed on the foundation, but on the beam frame to support the weight of the objects above and then pass through the beam.

frame structure to transfer the weight to the main column. For example, the ridge melon column or Shu column is the weight of the eaves that supports part of the beam frame.

Supported by a support, the external forces are subjected to transverse and shear forces.

The main component with bending as the main deformation is called a beam.
