How do you calculate the compressive strength of a structural steel beam w150 x 30?

I think you mean beam W30x150; where 30 is the nominal depth in inches, and 150 is the weight in pounds per linear foot. To answer the question about the compression strength, it is all relative to the type of steel, the length of the structural member, and how it is fixed at either end. Is it A-36 or A-50 steel; is it 10 ft. long, or 20 ft. long; is it pinned (bolted) or fixed (welded)? These unknown variables must be addressed before this theoretical value can be calculated.

What is the formula to calculate the yield moment for a column?
My= As*Fy*Jd As= Area of steel reinforcement (tensile steel only) Fy= yield strength of steel Jd= moment arm
What does A992Fy50 steel mean?
From wikiASTM A992 steel is a structural steel alloy often used in the USA for steel wide-flange beams (previously known as I-beams). Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m3. ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M. Tensile yield strength, 345 MPa (50 ksi); tensile ultimate strength, 450 MPa (65 ksi); strain to rupture (sometimes called elongation) in a 200-mm-long test specimen, 18 %; strain to rupture in a 50-mm-long test specimen, 21 %.ASTM A992 is the industry standard for all structural wide-flange beams.From the American Institute of Steel Construction: "ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) is the preferred material specification for wide-flange shapes, having replaced ASTM A36 and A572 grade 50. There are a couple of noteworthy enhancements with ASTM A992. Material ductility is well defined since a maximum yield-to-tensile strength ratio of 0.85 is specified. Additionally, weldability is improved since a maximum carbon equivalent value of 0.45 (0.47 for Group 4 and 5 shapes) is required. ASTM A992 is written to cover all hot-rolled shapes.
What is the difference between carbon steel and copper?
Carbon Steel is much stronger metal.
Whose 65Mn is called in other countries?
65Mn is equivalent to grade 1065 according to SAE J403. As Pressed mentioned, it is often cold-rolled and heat treated to high strength (called spring temper). ASTM A 29 is a standard for bar steel, so it is not appropriate for cold rolled strip. Grade 1065 is one of the grades covered by ASTM A 682 Standard Specification for Steel, Strip, High-Carbon, Cold-Rolled, Spring Quality, General Requirements for.
What is stronger than concrete?
steel
What is the ultimate compressive strength of steel?

What temperature does steel lose strength?
At about 550° C (1,000° F) Steel is at 50% Strength and at about 800° C (1472° F) structural steel loses 90% of its strength
Are a36 and tool steel the same?
No, A36 is a mild structural steel and tool steel is a high strength alloy steel
Is their any material that's stronger than steel and used in constuction?
Yes; most forms of concrete have a higher compressive strength than steel, though steel has the highest tensile strength of any commonly used construction material.
Why should one use steel in concrete?
Concrete has high compressive strength needed to sustain the weight of a structure but it has low shear strength (it can be deflected laterally ) and for this reason steel is used which prevents it from getting deflected laterally or buckle .
Compressive strength of 440C - Rc60?
440C Steel can be hardened upto 58RC unlike D2 (SKD11) which is upto RC 60 Hardness.
Why is tensile strength stronger than compressive strength?
Neither tensile strength nor compressive strength is inherently "stronger." Some materials are stronger in tension; other materials are stronger in compression. For example, rope is much stronger in tension than in compression, but concrete is much stronger in compression than in tension.
Different between cube and cylinder in concrete compressive test?
The difference in compressive strength is due to the difference between the modulus of elasticity of concrete and that of the steel which is used to apply the compressive force on the concrete. The pressure applies a lateral confinement pressure which is equal to d/3 meaning that for the cylinder, 2d/3 is confined leaving d/3 unconfined whereas for the cylinder 2d/3 is confined means all of the cube is confined. This leads to the cube having a higher compressive strength that the cylinder. For more information, try to read about the triaxial test and the effect of confinement on the compressive strength of soil samples.
What is the strength of steel reinforced concrete?
The reinforcment will have little or no effect on compressive strength. It will however impact tensile strength. It depends on the concrete mix design and amount of reinforcment, what the tensile strength impacts will be. The question needs to be a lot more detailed to provide a specific answer.
What is pns steel?

How long strength of concrete can rise and when will start to reduce?
The strength of concrete will continue to rise logarithmically forever. The rated strength is normally the 28-day strength, because at this point it will be at about 95% of its eventual strength, but it will continue to rise.Structural concrete is normally reinforced with steel. The concrete provides the compressive strength while the steel provides the tensile strength. It is a composite material, with the steel and concrete working together, but the steel can start to deteriorate compromising the strength of the composite structure - perhaps this is what you meant? When the steel corrodes the entire structure is weakened, since it relies on the tensile strength from the steel.As for when the will corrode, that is completely dependant on how it was constructed. The concrete cover over the reinforcing steel, the structural strength of the concrete, how the concrete was finished and cured, what elements the concrete is exposed to, the orientation of the concrete, the climate where the structure is built, whether there are any protective coatings on the concrete or not, the condition of the steel at the time of construction, whether or not the steel has any protective coatings or not, and many other factors all relate to the condition of the structure. If well designed, well build, and well maintained, a reinforced concrete structure can last 50 years or more with little to no signs of deterioration; however, with poor design, construction, workmanship, and maintenance, the structural integrity can me compromised in only months.If you're thinking about a future construction, make sure that it is well designed and built, and if you're talking about an existing structure and you have concerns, get it checked by a structural engineer.
