Structural steel is widely used in bridge construction due to its numerous advantages, which include:

High Strength and Lightweight: Steel offers high strength and is relatively lightweight, which reduces the overall weight of the bridge and enhances its load-bearing capacity.

Good Ductility and Toughness: Steel structures can absorb and dissipate energy effectively, providing excellent resistance to dynamic loads such as earthquakes and strong winds.

Short Construction Period: The prefabrication of steel components allows for rapid assembly on-site, significantly shortening the construction timeline.

Low Maintenance Costs: Steel is durable and requires minimal maintenance compared to other materials, leading to lower long-term operational costs.

Versatility and Creativity: Steel allows for the creation of complex and aesthetically pleasing designs, including long spans and innovative structural forms.

Recyclability: Steel is 100% recyclable, making it an environmentally friendly choice for sustainable construction practices.

These properties make structural steel an ideal material for bridge construction, offering a balance of strength, durability, and cost-effectiveness.
