Structural deformations are changes in the shape, dimensions or position of structural elements of a building caused by loads, environmental influences and material processes during service. They may be elastic in nature, disappearing when the load is relieved from the structure, or permanent, leading to irreversible changes in the geometry of load-bearing elements. They are a consequence of permanent and variable loads, such as:
- dead weight,
- payloads,
- snow and wind,
- temperature,
- humidity,
- shrinkage and creep of materials.
Their occurrence is a natural phenomenon and anticipated at the stage of the house design (of the building) through appropriate choice of sections, materials and structural solutions. Excessive or uneven structural deformations can cause damage to the finishes. They also result in the formation of cracks and fractures, disruption of the installation and a reduction in the durability and safety of the facility.
