Modular Expansion Joint

Design Principle

The design principle of IEC modular expansion joints focuses on accommodating large, multi-directional movements in bridge structures while ensuring durability and load-carrying capacity. The joint consists of multiple gap segments supported by centerbeams, edge beams, and support bars, allowing for smooth and controlled expansion and contraction. Elastomeric components, such as seals and bearings, absorb vibrations and shear forces, ensuring watertightness and stability under dynamic traffic loads. The modular design enables flexibility, facilitating adjustments for longitudinal, transverse, and rotational movements. This robust configuration ensures reliable performance in demanding conditions, including seismic zones and heavy traffic environments.
