H-beam is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter "H". Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.
H-beam is a steel widely used in construction projects. Its weight calculation method is relatively simple and can be calculated according to the following formula: H-beam weight (kg/m) = 0.00785×[h×(b1+b2)/2×t1+(h-t1)×b3×t2]
Where: h is the height of the H-beam, b1 and b2 are the widths of the upper and lower flanges, t1 is the thickness of the upper and lower flanges, b3 is the width of the waist plate, and t2 is the thickness of the waist plate. The steel density is 7.85g/cm3.
Application case:
Suppose there is an H-beam with the specification of 200×200×8×12, where 200 means the height of the H-beam is 200 mm, 8 means the thickness of the upper and lower flanges is 8 mm, and 12 means the thickness of the waist plate is 12 mm. Assuming that the widths of the upper and lower flanges are equal, b1=b2=75 mm, and the width of the waist plate is b3=10 mm, then the weight of the H-beam can be calculated according to the above formula:
H-beam weight (kg/m) = 0.00785×[200×(75+75)/2×8+(200-8)×10×12] =50.1kg/m
Therefore, the weight of the H-beam per meter is 50.1 kg.
If you need to calculate the total weight of the H-beam, you can convert it according to the length. For example, if the length of the H-beam is 6 meters, the total weight is 50.1kg/m×6m=300.6 kg.
H-beam size representation method:
The H-beam size representation method is actually very simple. It is usually to multiply the width of the H-beam by the height and then by the overall thickness, and then by the thickness of the entire steel belly. In general, the size representation method of this steel is H=abc*d, where each letter represents a corresponding size.
For example, the size of an H-beam is 200*100*5*8mm, which means that the height of this H-beam is 200mm, the width is 100mm, the web thickness is 5mm, and the flange thickness is 8mm. Through this representation method, the specific size of the H-beam can be intuitively understood, which is more convenient when purchasing and using.
This clear size representation method is not only easy to remember and communicate, but also provides great convenience for architectural design and construction. When choosing a suitable H-beam, you can accurately find the steel specifications that meet the requirements according to the needs of the architectural design.
The difference between H-beam and I-beam:
Although H-beam and I-beam are both commonly used steels, they have significant differences in structure and use.
First, the cross-sectional shape of H-beam is the same as the English letter H, while the cross-sectional shape of I-beam is like the English letter I. Since the flange of H-beam is wider and the web is thicker, its bending and shearing capacity is stronger than that of I-beam, and it is more suitable for bearing larger loads.
Secondly, the classification of H-beam is more diverse. According to the width of the flange, H-beam can be divided into three types: wide flange, medium flange and narrow flange. I-beam belongs to ordinary I-beam, and the classification is relatively simple.
Finally, H-beam has more advantages in terms of strength-to-weight ratio. Due to its superior cross-sectional performance, H-beam uses less steel under the same load conditions, which can save material costs and improve economic benefits in practical applications.
Matters needing attention when purchasing steel:
When purchasing steel, you need to pay attention to the following aspects:
First, pay attention to the structural part of the steel. There are many types of steel. When purchasing, you should choose steel of appropriate quality according to the actual situation. For example, for structures that need to bear large loads, you should choose steel with high strength and good toughness.
Secondly, for different use environments, you should also make corresponding judgments. For structures working in low temperature environments, you should choose steel with good low temperature resistance to prevent brittle fracture of steel under low temperature conditions. For structures working in high temperature environments, you should choose steel with good high temperature resistance to ensure that the steel does not deform or corrode under high temperature conditions.
In addition, when choosing steel, you should also pay attention to purchasing products from regular manufacturers. Don't buy inferior steel for cheapness, which will not only affect the safety of the building structure, but also may bring serious safety hazards. Therefore, when purchasing steel, you should try to choose a regular manufacturer with good reputation and guaranteed quality.
H-shaped steel is widely used in modern construction projects. Its size representation method is simple and clear. When purchasing, you need to choose the appropriate specifications and types according to specific needs, pay attention to the structural properties and environmental adaptability of the steel, and choose products produced by regular manufacturers to ensure the safety and stability of the building structure.
