How Strong is an H-Beam to Support the Load on a Bridge?

Bridges are one of the structures that must have extraordinary resistance to various loads, ranging from heavy vehicles to environmental pressures such as wind, earthquakes, and temperature changes. One of the main materials used in bridge construction is H-Beam, thanks to its strength and stability. But, how strong is H-Beam in supporting the load on the bridge?

1. Strong and Stable H-Beam Construction
H-Beam has an "H" shaped design with a wider and thicker flange than I-Beam, so it can withstand greater loads with a more even distribution. This characteristic makes it very suitable for use on the main beam of the bridge which must support large amounts of dynamic and static loads.

2. H-Beam Bearing Capacity
The strength of H-Beam in supporting loads is highly dependent on the size and type of steel used. In general:

H-Beam with specifications H200 x 200 x 8 x 12 mm has a bearing capacity of around 20-30 tons per bar depending on its length.

H-Beam with specifications of H400 x 400 x 13 x 21 mm is capable of withstanding loads of more than 100 tons, which is often used in large bridge projects.

3. Flexibility in Withstanding Dynamic Loads
Bridges often face dynamic loads from passing vehicles. H-Beam has a combination of high tensile and compressive strength, making it able to withstand shear forces and prevent excessive deformation. In addition, the elastic properties of steel in H-Beam help bridges remain sturdy even though they experience repeated pressure from heavy vehicles.

4. Resistance to Environmental Factors
Bridges are often exposed to rain, wind, and even earthquakes. Structural steel such as H-Beam can be processed with anti-corrosion and galvanization treatments, making it more resistant to rust and other external factors. This makes the service life of bridges using H-Beam longer than other materials.

5. Use of H-Beam in Bridge Construction
H-Beam is often used in various types of bridges, such as:
✅ Steel beam bridges - Become the main element in the support structure.

✅ Truss bridge – Used as the main component of the steel frame.
✅ Flyover – Used in the lower frame to increase durability and stability.
