What is the main advantage of using disk bearings in bridge construction?

The primary advantage of using disk bearings in bridge construction is their very low profile. This characteristic allows for a more compact design compared to other bearing types, which can be crucial in scenarios where vertical clearance is limited. The low-profile nature of disk bearings helps in maintaining a minimal height, facilitating better site utilization and allowing for more streamlined integration of the bridge structure into its surroundings.

In addition to space-saving advantages, the low profile can also contribute to the overall aesthetic of a bridge by reducing the visual bulk of the supporting elements. This aspect can be especially important in urban or scenic environments where the bridge's appearance plays a significant role in the overall landscape.
