The 6 meter span is made of 300H steel beams, and 250H steel is used as columns

I will make two points. 1. In fact, for the steel beam with a relatively large span similar to the lighting roof, the dead load (that is, the steel beam self-weight + weight) only accounts for a small part of the load combination, and the control load is the wind load. And what is the load of the weight?

Concentrated or Uniformly Distributed Loads? It makes sense whether the load is distributed in the middle or close to the support.

Second, if you don't understand structural calculation, you still need to find someone to help you calculate, structural computing is a matter of human life, don't do it easily. I heard about a very impressive thing, a structural engineer, calculated a steel structure, did a good job. Someone moved the thing he counted to another place and used it, and it collapsed before it was finished.

The structurist committed suicide upon hearing the news. Later, I learned that there was no problem with the calculation, but the foundation conditions and wind pressure values were different in the two places. Having said all that, I hope you will consider it carefully.

The thickness of the material is not, to give you a data, see for yourself, the thickness is not equal, and the load bearing: between.

With a span of 6 meters, can the main beam of 300*150* H-beam bear 5 tons? Thank you.

With a span of 6 meters, can it bear 5 tons of weight with 300*150* H-type burning steel as the main beam? Thank you, you are so pro, 300 high H-beam, 6 meters span, carrying 200 kg of uniform load is no problem. I hope my answer is helpful to you, <>

Summary. Generally, the bearing weight of H-beam is related to its specifications, and the bearing capacity of H-beam with an area of 200*200 is at least the minimum ton.

200 200 H-beam as a beam can withstand how many tons of weight one meter.

Generally, the bearing weight of H-beam is related to its specifications, and the bearing capacity of H-beam with an area of 200*200 is at least the minimum ton.

Is a meter middle part theoretically load-bearing?

Good. Assuming that the mass density δ = first calculate the mass mass of the steel beam = δ length * width * thickness = * 1m * = consider the longitudinal compression and transverse bending load of the steel (solid H-beam), use the common Zen sum equation *q=f 4*s =, q represents the force area (cm 2), f represents the force (n), and s represents the cross-sectional area of the steel element (cm 2) first calculate the cross-sectional area ss=200 200mm2 , 1mm2=Therefore, f= *q*4*s q represents the force area, The width of the H-beam is 200 200mm, and the stressed area can be regarded as 200mm 200mm= 40000mm, q=40000 cm 2=400 cm2 Therefore, f= *q*4*s = = 672000n Finally, the bearing capacity of the one-meter beam f=672kn multiplied by the gravitational acceleration can be calculated, and the unit is changed from n to hail attack n672kn=therefore, this h-beam can bear tons of weight.

I've worked hard to calculate it, but I don't know if it's correct, dear.

If the calculations are wrong, this side may not be able to help you, dear <><

The span is 6 meters, and the beam is made of hn200*100*H beam, how much load can it bear (uniform load and concentrated load).

According to the strength calculation, the span of 200 unreed H beam of 4 meters can bear how much positive pressure can be subjected to; If this section of the steel beam as a simply supported beam, the concentrated load force in the beam of the missing midpoint, the bending moment is the largest, the cross-sectional modulus of 20A I-beam is 237cm, if the allowable stress takes 160MPaThe maximum bending moment that this beam can withstand is 3792kgm. By the maximum bending moment w=ql 4.

This beam is subjected to the maximum concentrated load tonnes. (The cross-sectional modulus of 20B I-beam is 250cm, and if the allowable stress is 160MPa.)The maximum bending moment that this beam can withstand is 4000kgm.

The beam is subjected to a maximum concentrated load of 4 tons. )

With a span of 5 meters, how much load can be carried by using 150 150 H-beam as the main beam?

5 meters span, with section steel as the vertical beam load ton, the calculated cross-section flexural modulus is 107cm3, which is the maximum allowable concentration of the arubber core in the case of simple support at both ends.

How many tons of weight can the national standard H-beam 450X350 8 meters long carry? It is mainly used to make girders, and how many tons of weight can be carried by the beam span of 8 meters.

The H-beam is a medium-wing H-beam that can weigh up to 30 tons. There are specifications of 294*200*9*12 in the national standard. According to this specification, the span of 8 meters is a bit large, or the cross-section of the beam is a little small, only strong or equivalent to the roof purlin.

Can't bear too much weight. It is recommended to use H-beam above 600*300*12*18. The following is the calculation method of H-beam load-bearing:

Ra=RB=P 2 mc=mmax=PL 4 FC=Fmax=PL 3 48EI A= B=PL 2 16EI Symbolic meaning and unit p -- concentrated load, n; q - uniform load, n; r - support reaction, the direction of action is positive, n; m - bending moment, so that the upper part of the section is compressed, and the lower part is positive, nm; q - shear force, the moment generated by the adjacent section is positive along the clockwise direction of the cavity hole, n; f - deflection, positive for downward displacement, mm; Corner, the one that rotates in the clockwise direction is positive, °; E – modulus of elasticity, GPA; i – axial moment of inertia of the cross-section, m 4; ξx/l,ζ=x'l, a l, =b l, =c l are considered from two aspects: first, from the shear stress of the beam and second, from the bending normal stress. From the section table, you can find its maximum usable shear strength t tmax=q ib[bh 2 8- 8] where:

tmax is the maximum shear strength. By substituting the available shear strength t, the maximum load of the beam can be calculated. q is the uniform load i is the cross-sectional moment of inertia of the I-beam can be found in the section steel table (cm 4).

b is the maximum width of the I-beam section. b is the minimum width of the I-beam cross-section, and h is the height of the minimum width of the I-beam. h is the height of the maximum circle width section of the I-beam Calculation of normal stress:

ysigma=m w m=maximum bending moment=load times distance w=flexural modulus. Let ysigma= maximum allowable stress to give the maximum value of the load.

The 7-meter span is made of 300h steel beam, 250h steel is used as a transverse beam, and 250h steel is used as a column.

Hello dear, glad to answer for you. The 7-meter span is made of 300h steel with transport beams, 250h steel for transverse beams, and 250h steel for columns. 300H steel, one meter has a load-bearing of 48 to 53 kilograms, that is to say, the cross-cavity beam degree of 7 meters of Lao Zhu 300H steel, can bear 336 to 371 kilograms, that is, to tons.

The results have been queried for you: Based on the information you provided, I can make a preliminary estimate for you. Note, however, that this is only a rough estimate and does not take into account the influence of other factors on the strength and stability of the structure.

Assuming that the H steel of the erection column uses Q345B material (tensile strength is 470MPa), then its cross-sectional area is: a = 300mm * 150mm - 250mm * 100mm = 37500 mm According to the cantilever beam formula, the maximum bearing capacity of the column when bearing the uniform load is: w = max * a) n where n represents the safety factor.

Under normal liquid conditions, n=4 is more common. max represents the maximum allowable stress value for the material, which in this case can be calculated as 470MPa. Substituting the data into the formula yields:

w = 470 mpa * 37500 mm ) 4 * 1000) 4395 kg Therefore, under ideal conditions (i.e., no other factors are considered), the column H steel is capable of bearing a uniform weight of about 4395 kg (about tons) at a meter height and meter span. Hope mine is helpful to you.

Summary. It is calculated that the height of the column H steel of 300*150 is meters. The span bears weight in kilograms per meter.

It is calculated that the height of the column H steel of 300*150 is meters. The span bears weight in kilograms per meter.

H300X150 is a narrow flange hot-rolled profile, the complete expression is that H-beam is a cross-sectional area allocation is more optimized, the strength-to-weight ratio is more harmonious economic section high-efficiency profile, because of its liquid break imitation front and the English letter "H" grandson is the same name.

H-beam is a kind of high-efficiency cross-sectional section with more optimized cross-sectional area and more reasonable strength-to-weight ratio, which is named because its cross-section is the same as the English letter "H". Because all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction of poor history, cost saving and light structural weight in all directions, and has been widely used.
