Description

Technical Field

[0002] As vital lifeline structures, bridges that remain functional after an earthquake are crucial for earthquake relief efforts. However, the functional capacity of bridges depends primarily on the extent of damage to their piers. Model testing is a common method for studying complex bridge structures and serves as an important basis for validating numerical and analytical theories. By creating scaled-down pier models and simulating damage to piers caused by underwater vibration, researchers can study the impact of earthquake vibrations on piers, bridge engineering, marine engineering, and other structures involved in water environments.
