It depends on the steel you choose, and the cross-section of the beam.
The total weight is 25 tons, the span is 6 meters, and it may not be enough to support it with reinforced concrete, and it is necessary to know the connection between the steel bar and the support.
The landlord gives detailed information, the type of steel, and so on.
The huge calculation of the huge length was wrong in the first step of calculating the bending moment, multiplying it by a safety factor of 6 that I used.
Bending moment m 300* is less than 1 3 of that data q (force per unit length) and p (total weight) are 2 different data Thank you.
It is enough to use 5 25 and 2 18 600*300 cross-sections.
The formula for bending moments is shown in the portal.
The domestic bending moment algorithm is impossible to be different from this.

6 meters span 240 600 suspended beam bearing 30 tons how to reinforce.
Kiss, <>
We are glad to answer for you, oh 6 meters span 240 600 suspended beam bearing 30 tons of reinforcement in general rural self-built houses, the span of more than 6 meters of load-bearing beams can be set as pressed: 1. Beam section: 200 * 650mm or 240 * 600mm or 300 * 500 550mm; 2. Main rib:
4 20 at the bottom, 2 16 through length at the upper two corners, plus 1 short steel bar of 16 in the middle of the end (2000 2300mm extending into the beam span); 3. The actual strength of concrete is not less than C26. In addition: the above only considers that the beam bears the weight of the upper one to two floors (such as the beam is on the top of the first floor, the upper position only has a ring beam and no beam, and the total height of the building is only two floors plus the top floor), if the weight borne by the beam increases, the setting of the beam should also be enhanced accordingly.
Extended data reinforcement refers to the operation process of setting up steel old qiao ribs in the clear potato concrete and designing, processing and configuring them in order to enhance the bearing capacity of concrete. Hope mine can help you! <>

How much can a 24*30 span 6m beam bear.
Hello dear! Glad to accompany you with your questions! How much can a 24*30 span 6m beam bear. According to the requirements of the building construction code, the height of the wall carried by the 24x30 cantilever beam is about 3 meters.
According to the requirements of the building construction code, the height of the wall carried by the 24x30 cantilever beam is about 3 meters. C30 according to the design value of the socks, 30x30cm column can carry 128 tons of many buildings, the ground beam must exist, as the name suggests is to highlight the ground beam, its main role is also used to bear the weight of the reed cavity and stabilize the role of the building. Then the 50 cm floor beam is already relatively thick, so it can withstand a house of about 6 floors.
Houses with more than 6 floors may require larger floor beams, but all house construction is carried out according to specific drawings, which are also drawn by countless professionals. In addition, the ground beam is inseparable from the foundation, and the foundation also needs to be laid deeper.

To design the reinforcement of the 10-meter span suspended beam, it is necessary to first understand the design characteristics and mechanical principles of the suspended beam, and then carry out structural calculations according to the specific construction conditions and load requirements. Here are the general design steps:
1.According to the design load and span, the cross-sectional shape and length of the cantilever beam are determined, and the rectangular or T-shaped section is generally adopted.
2.Based on the cross-section shape and length, the stress state is calculated, including internal forces, shear forces, and bending moments.
3.According to the specification of reinforced concrete structure design, the appropriate type of reinforcement and reinforcement method are selected, and the cross-sectional area and position of the reinforcement are calculated to meet the requirements of structural strength and stability.
4.According to the design requirements and local construction standards, formulate specific construction plans and steel processing plans, including the length, diameter, bending radius and spacing of steel bars, etc.
5.In the construction process, it is necessary to strictly follow the design drawings and construction plans for steel processing and installation to ensure the quality and accuracy of steel bars.
It should be noted that the design and construction of cantilever beams must meet the requirements of local building safety standards and codes, otherwise it may pose a threat to personal safety. Therefore, it is essential that the design and construction must be carried out by professionals with the appropriate qualifications and experience to ensure the quality and safety of the project.
In addition, for the design and reinforcement calculation of the 10-meter span suspended beam, the following aspects need to be considered:
1.Self-weight and load requirements of cantilever beams: The self-weight and load requirements of cantilever beams will directly affect the number and arrangement of reinforcement. In general, the greater the load, the greater the number of reinforcements and the greater the cross-sectional area.
2.The protective layer of the steel bar: The protective layer of the steel bar refers to the distance between the concrete and the steel bar, and the thickness of the protective layer should meet the local specifications. In general, the greater the thickness of the protective layer, the longer the service life of the rebar.
3.The cohesion of the steel bar: the cohesion of the steel bar refers to the binding force between the steel bar and the concrete, the stronger the steel bar, the stronger the bearing capacity of the suspension beam. In order to ensure the cohesion between the steel bar and the concrete, it should be processed and installed correctly in accordance with the requirements of the code.
4.Fatigue strength of steel bars: Fatigue failure may occur in the process of long-term use of cantilever beams, so the fatigue strength of steel bars is also a factor to be considered.
Fatigue analysis should be carried out during the design and appropriate measures should be taken to improve the fatigue strength of the reinforcement and the service life of the cantilever beam.
In short, the design and reinforcement calculation of cantilever beams is a tedious and important work, which requires rigorous calculations and correct design and construction plans to ensure the quality and safety of the project.

I have summarized the following points for you:
The 10-meter span suspended beam is a single-end fixed cantilever beam, which needs to withstand large shear forces and bending moments, so it is necessary to design sufficient cross-sectional dimensions and reinforcement reinforcement.
The top of the suspended beam is under tension, so it is necessary to arrange the main reinforcement at the top and extend into the support wall to meet the anchorage length. The bottom is compressed, so a small amount of rebar needs to be arranged at the bottom to resist temperature stress and crack control.
Reasonable node forms and details need to be set between the suspended beam and the supporting wall to ensure the integrity and stability of the structure. Commonly used node forms include embedded, embedded, connector, etc.
The design of the suspended beam also needs to consider the requirements of deflection control, crack control, durability and so on to ensure the safety and performance of the structure.
Based on the above principles, I have generated a possible reinforcement design for you:
Suppose the cross-sectional size of the suspended beam is 300 500 mm (width and height), the concrete strength grade is C25, and the reinforcement strength grade is HRB400.
According to the load analysis, the maximum shear force of the suspended beam is v max = 150 kn, and the maximum bending moment is m max = 750 kn·m.
According to the ultimate strength design method, the required top main reinforcement area is A s1 = cm 2, the required bottom main reinforcement area is A s2 = cm 2, and the required stirrup spacing is not greater than s v = 15 cm.
According to the national standard GB50010-2010 "Code for Design of Concrete Structures", the top main reinforcement can be selected to adopt 4 20 mm steel bars (A S1 = cm 2 > cm 2), the bottom main reinforcement adopts 4 12 mm steel bars (A S2 = cm 2 > cm 2), stirrups use 8 mm steel bars, and the stirrup spacing is set according to the change law of S v 3-S v 6-S V 3 (i.e., 5-10-5 cm).
According to the national standard GB50011-2010 "Code for Seismic Design of Buildings", embedded nodes can be selected as the connection mode between the support wall and the suspended beam, and the details such as infill stirrups, anchorage length, and protective layer thickness in the node area can be set according to the requirements of the code.
Of course, this is just a simple example, and it's not perfect. You can adjust or refine it according to your specific situation and needs.
Hope mine is helpful to you. If you have any further questions, please feel free to ask.
