What is meant by 'lateral support' in foundation systems?

Lateral support in foundation systems refers to the mechanisms that prevent the walls of a foundation from tipping or collapsing sideways. This is essential for maintaining the structural integrity of the building, especially during lateral forces such as wind, earthquakes, or soil pressure from slopes. A robust floor system can provide this type of support by distributing loads evenly across the foundation walls, ensuring that they remain stable and upright. Therefore, the concept of lateral support is crucial in safeguarding the foundation against any horizontal movements or forces that could compromise its stability.
