1. Differences in definition and structure

(1). Flange Beam:

Flange beams, also known as H-beams or wide flange I-beams, have a cross-sectional shape similar to the English letter “H”. This type of steel has a relatively high section modulus and moment of inertia, and is capable of withstanding large bending moments and shear forces. Its flange is relatively wide, which makes the connection and welding more convenient and enhances the overall stability of the structure.

(2). Rectangular Beam:

Rectangular beams are common bending structures in highway traffic engineering, and their cross-sections are rectangular. Under the action of load, the upper edge of the section bears pressure and the lower edge bears tension. Because the cross-sectional shape of the rectangular beam is simple, its construction is also relatively easy.

 

2. Performance advantages

(1). Performance advantages of flange beams:

High strength and stability: Due to its unique “H” shaped section, the flange beam has a high section modulus and moment of inertia, capable of withstanding significant loads while maintaining structural stability.

Convenient connection: The flange is relatively wide, making it easier to operate during the connection and welding process and improving the construction efficiency.

Wide application: Flange beams are widely used in various building structures, Bridges, mechanical vehicles, supports and other occasions that need to bear large loads.

(2). Performance advantages of rectangular beams:

Simple structure: The cross-sectional shape of the rectangular beam is simple, which is easy to manufacture and construct, reducing costs.

Convenient reinforcement: In scenarios where positive and negative bending moments alternate, rectangular beams have application requirements due to their convenient reinforcement.

Wide application: Although the material utilization rate is relatively low in single bending moment scenarios, rectangular beams are still widely used in bridge construction.

 

3. Summary

Flange beams and rectangular beams each have their own advantages in structure and performance. Flange beams play a significant role in various situations where they need to bear large loads due to their high strength, stability and convenient connection. Rectangular beams have occupied a place in highway traffic engineering due to their simple structure, convenient reinforcement and wide application.
