Comparative Study for Expansion Joint Type Selection on Bridges with High Seismic Movements.
Keywords:
Expansion joint, modular expansion joint, finger expansion joint, deck movement on bridges, bridges in high seismic zonesAbstract
Expansion joints play a critical role in safely allowing movements in bridges due to temperature, shrinkage, creep, dynamic movement from traffic and seismic demands. For bridges in high seismic zones, movement demands can be significantly higher, hence selecting a proper expansion joint type is essential for ensuring the bridge performs as expected and maintain uninterrupted traffic flow. This study evaluates modular and finger expansion joint types based on space requirements and movement demands. A comparative analysis is performed using available supplier data. The findings of this research aim to assist engineers in selecting a proper expansion joint type.
