Concept
According to the principle of superposition
For a linearly elastic structure, the load effects caused by two or more loadings are the sum of the load effects caused by each loading separately.
Note that the principle is limited to:
• Linear material behaviour only;
• Structures undergoing small deformations only (linear geometry).
It is not applicable when:
1. The material does not obey Hooke’s law.
2. The effect of temperature changes are taken into consideration.
3. The structure is being analysed for the effect of support settlement.
