What is the minimum bearing for a steel beam?

Steel beam design

The problem is that the steel beam has a much higher resistance capacity than the factory on which it rests, hence it is convenient to make a transition with something, steel plate or whatever. When I say whatever it is, it depends on whether the load-bearing wall is made of concrete or factory, which is much less resistant, and you can’t put the steel plate on a brick wall.

the bearing wall, sorry for not saying it before, is brick, 25 cm, old wall, so of course my concern is that it is quite narrow and I do not like at all the direct delivery of the beam in the wall. what do you recommend, make a zunchito under concrete and under this a 3 cm expanded polystyrene, or what are your solutions?

One of the solutions that they use the most when they do not have a project (yes, here many works are done without project) is the one foot bearing walls with perforated brick and HEB-220 beams as beams. They use the 220 because they can put the joists between the flanges.

Design of structural steel columns

Before knowing how to calculate the weight supported by a beam, it is necessary to know a little more about this material. It is a structural steel cross-section profile, which is characterized by having a structure in the shape of the letter I or H. It is known as a “universal beam” or for thicker sections as a “universal column”.

The weight that the IPR beam is able to support is related to the use it has as a material since it is used to create lighter structures, therefore it will weigh around 400 kg, which is less than a quarter of the weight of a concrete beam that can weigh two tons. Therefore, using steel beams in your construction will allow you to reduce the total weight of the structure and this will be reflected in significant savings in the cost of the foundation.

In order to determine the weight of the IPR beam, you must know that it is a material that is determined according to its volume and density, for example, an iron beam has a higher density than a wooden one; therefore, two beams of the same volume will differ in mass if they are built with different materials. Therefore, it is important to keep in mind that mass and weight are different quantities.mass refers to the amount of matter in an object, while weight is the force required to lift the object. Weight is determined from mass.

Steel beam support on brick wall

Abstract: Columns are those vertical elements that support compression and bending forces, in charge of transmitting all the loads of the structure to the foundation; that is to say, they are one of the most important elements for the support of the structure, so their construction requires special care.

“As the concrete is poured into the column, it must be consolidated with conventional vibrators, in order to remove the air that is trapped during the process and achieve the rearrangement of the aggregates for a uniform distribution”.

Dear Eng. Omar Javier Silva First of all, excellent article on the construction of concrete columns, especially a great idea for the construction work environment, so that thanks to the reinforcement of each column itself will be obtained buildings with better results. Greetings.

Engineer I have a question I have a lot of 6×11 in which has 12 columns of 40 centimeters wide x 10 centimeters each column is composed of 6 rods of average and strips to 7 cm of rod 7 the question is this building how many floors can hold the simientos where each column is 1. 20 deep by 1 meter wide with its respective mesh rod 1/2 filled with stone and concrete thank you very much for your attention and I look forward to your prompt response.

Pre-dimensioning of steel beams

The first two points are solved by the flexural design of the beam. However, the support of a steel beam on a wall requires taking into consideration the problem of load transmission of the beam on the wall and the possible concentration of load on the beam heads, as in the case of load-bearing beams.

Well, we already have some mortar in the support die. The mortar will guarantee that the contact between the profile and the masonry is complete. The support of a steel beam in a wall is usually solved this way, just like that. However, this does not guarantee that the admissible tension is greater than the load of the profile. For this reason, a steel plate is installed. By welding the beam, the load concentrated on the flange is distributed over the entire width of the wall. To fix the plate to the die, welded round bars are used. This ensures that the plate does not slip on the concrete.
