Introduction to the concept of rigid foundation

The rigid foundation is a foundation structure that transmits the loads of a building or infrastructure to the ground, characterized by its structural rigidity that allows the loads to be distributed uniformly and minimize differential deformations. It is commonly used in projects where the terrain has variable conditions or where the loads are concentrated and require a solid and stable support.

This type of foundation is characterized by generally being composed of a slab or a monolithic reinforced concrete structure that acts as a rigid plate, avoiding relative displacements between its different parts. Its design and construction must guarantee the structural integrity and the load-bearing capacity necessary to withstand the building's loads and external forces, such as earthquakes or settlements.

Structural rigidity and load behavior

The main attribute of the rigid foundation is its high rigidity, which implies that the structure acts as a solid element that distributes loads uniformly over the ground. This feature minimizes settlement differences between different points of the foundation, reducing the possibility of cracks or structural failures in the superstructure.

This rigid behavior is essential in heterogeneous terrain or in buildings with concentrated loads, as it allows the foundation to function as a stable base that absorbs and redistributes stress, avoiding stress concentrations that could compromise stability.

In addition, the rigidity of the rigid foundation contributes to increasing the bearing capacity of the foundation, by distributing the loads over a greater surface area and reducing the point pressure on the ground, which is crucial to avoid excessive settlements or failures due to load capacity.
