What are the different types of expansion joints in structural engineering?

1. Movement Joints: These are used to take care of the movements caused by temperature and humidity variations.

2. Compression Seal Joints: Used to accommodate structural movements due to factors like thermal expansion, wind, and seismic activities.

3. Strip Seal Joints: These are appropriate for mostly bridge decks and parking garages. They prevent debris, water, and dirt from entering the expansion joint.

4. Finger Joints: Mostly used in small structures like concrete pavements, pedestrian walkways, and airport tarmacs.

5. Modular Joints: It allows broad movements and offers protective support to the edges of the expansion joint.

6. Sliding Plate Joints: These are popularly used for large bridges and rail tracks. It allows smooth slide movement and free expansion without any damage.
