Understanding the uplift capacity of shallow foundations is a crucial aspect of structural and geotechnical design, particularly for lightweight structures such as steel frameworks and sheds. In these cases, uplift forces induced by lateral loads can become a significant design consideration, often challenging traditional assumptions about soil-structure interaction.
Commonly used approaches, such as relying on the weight of soil above the footing or applying a 30-45° angle method, may yield quick estimates but often oversimplify the underlying mechanics. Uplift capacity is not just about soil weight; it also involves friction, cohesion, and safety factors, all of which play critical roles...
