Question: 1 / 400

What are "expansion joints" used for in construction?

To enhance structural integrity during earthquakes

To accommodate movement due to temperature changes or settling

Expansion joints are essential components in construction designed to accommodate movement due to temperature changes, settling, and other environmental factors. As materials heat up and cool down, they expand and contract. Without the presence of expansion joints, this movement can lead to cracking, buckling, or other structural failures in materials such as concrete, asphalt, and various building elements.

These joints effectively allow for controlled movement, preventing stress from building up and damaging the structure. By incorporating expansion joints, builders can ensure longevity and stability in their structures, especially in areas with extreme temperature fluctuations or where subsurface conditions may change over time.
