Assuming that the structure is supposed to work similarly from day to day, if the everyday stresses exceeds the yield stress of the material, the structure will gradually deteriorate from plastic deformations, and finally be destroyed or lose its function. Over time, fatigue will most probably occur as well.
Measures to keep everyday stresses lower than the yield stress of the material may include proper design, inspections, maintenance, load management, field data reports, and material testing.
Proper design and choice of material  can help to ensure that the stresses in the structure are kept well below the yield stress of the material.
Regular inspections can identify any areas of the structure where stresses may be building up beyond safe limits. This allows corrective action to be taken before significant damage occurs.
Regular maintenance can identify and address issues, such as corrosion or wear, that may contribute to stress buildup.
Careful management of the loads that the structure is exposed to can help to keep stresses within safe limits. This may involve limiting the weight of loads, distributing loads evenly across the structure, or using support structures to reduce stress concentrations.
Collection of field data by following up a set of products.
Regular testing of the material can identify any changes in its properties that may affect its ability to withstand stress. This can help to prevent failures due to changes in material properties over time
