What size steel beam to use for load bearing wall?
Twelve-inch-thick steel beams can be used in the basement. They can run 16 feet or longer without steel columns in the middle. While considering the types of beams to use for your load-bearing interior walls, make sure that the columns that will support the beams are standing on solid footing.
How do I calculate beam size?
How do I calculate beam size? The formula for the section modulus is beam width times beam depth squared divided by 6. A two 2-by-6 standard beam has actual dimensions of 1. 5-by-5. 5 inches which would give a section modulus of 1. 5 x 5. 5 / 6 = 7. 6 which is not enough for this example. A 2-by-8 beam would be sufficient.
What is bearing capacity of a beam?
The bearing capacity is calculated by multiplying the loaded area times the standard compressive strength times a factor kc. Both standards refer only to one specific design situation given in Fig. 5 in which two beams overlap. One is the continuously supported bearing beam locally loaded by the top beam.

How do you calculate loading capacity?
To calculate the capacity load ratio you must divide the required hours on a project by the amount of time available to complete it and multiply it by 100. For instance, if a project designer requires 80 hours to complete a project but they only have 60 hours available, they are at 133% — meaning they are overloaded.

In summary, the back-calculation of the beam design process gives the procedure for computing the load-carrying capacity of a reinforced concrete beam.
How to transfer loads from a slab to a beam?
For a one-way slab, half of the total load on the slab goes to a beam from one side, and the other half goes to the other side of the slab. For two way slab, the tributary area can be used to transfer loads to the beams on all sides of the slab.
How much live load should I use for a slab?
Estimate the live load on the slab based on the function of the building. For instance, use 2.4 KN/m 2 (50 psf) for offices, as per Table 4-1 in ASCE standard (ASCE/SEI 10-7).

How to determine the number of steel bars?
However, if the design detail is not available, determine the number of bars using non-destructive tools or break a small portion of the beam to expose steel bars and then count the number of bars.
How do headers and beams work?
The job of headers and beams is a simple one. They transfer loads from above to the foundation below through a network of structural elements. The idea behind sizing headers and beams is straight-forward: Add together all live loads and dead loads that act on the member and then choose a material that will resist the load. The beam must be strong enough so it doesn’t break (Fb value) and stiff enough so that it doesn’t deflect excessively under the load (E value). However, the process for sizing these structural elements can be complicated if you are not an engineer. Here is a simplified approach that will help you specify the appropriate material for many applications.
How much load does a roof carry?
Here, each square foot of roof system delivers 50 pounds of live load and 15 pounds of dead load (65 psf total) to the structural support system . Remember, these loads are distributed uniformly over the entire surface of the roof. The exterior wall (and the headers within) will carry all loads from the mid-point of the house (between the supporting walls) to the outside of the house (including the roof overhang). The distance in this case is 12 ft+ 2 ft = 14 ft. So, each lineal foot of wall must carry the loads imposed by a 1-foot wide strip in that 14 ft region. In technical terms, the wall has a tributary width of 14 ft. From this we can readily see that each lineal foot of wall supports:
What is a distributed load?
Loads are considered to be either distributed or point loads. A layer of sand spread evenly over a surface is an example of a pure distributed load. Each square foot of the surface feels the same load. Live and dead loads listed in the building code for roofs and floors are approximations of distributed loads. Point loads occur when a weight is imposed on one spot in a structure, like a column. The load is not shared equally by the supporting structure. Analysis of point loading is best left to engineers. We will consider only distributed loads. This will enable us to size beams for most common applications.
Why is it important to list live load, dead load and total load separately?
It is important to list live load, dead load and total load separately because live load is used to compute stiffness and total load is used to calculate strength.
How much does an 8 foot tall wall weigh?
Loads are contributed to the lower header by the roof, upper walls and 2nd floor system. The Architectural Graphic Standards lists the weight of an exterior 2×6 wall as 16 pounds per ft 2. So an 8-foot tall wall weighs 8 ft x 16 pounds/ft 2 = 128 pounds per lineal foot. The loads delivered to the header are:
How to calculate maximum bending moment?
Using the formula Working stress = My/I calculate the load. Moment M will be in terms of the (Unknown)Load and cross sectional properties (known). Working stress = Yield strength of the material of the beam divided by factor of safety.

How to find yield strength?
Yield strength times the section modulus divided by 1.67. Will give you your max allowable moment. Then back into your uniform load from there. 8M/L^2=w if it’s a simple beam. You can find the section modulus and yield strength in the AISC construction manual. The 1.67 is your omega (safety factor) using ASD.

When you calculate stress from this equation (knowing force and cross-sectional area) can you compare it with?
When you calculate stress from this equation (knowing force and cross-sectional area) you can compare it with maximum allowable stress (usually yield point) to see how big force can your column/rod handle.
How to find maximum moment of steel?
Well, you know the yield stress for whichever grade of steel you are using, as well as the section properties of the I-beam you are using. The old sigma = M*c/I equation will do the trick here. Simply back solve for the maximum Moment using the yield stress as sigma. Then, find what loading produces that maximum moment. That should be adequate for design purposes.
